Optimizing Machining Processes with High

Milling is a crucial manufacturing process used to create components with complex geometries. It is essential to optimize the geometry of the inserted piece for improved chip evacuation, in order to achieve a higher quality and more efficient milling process. In this article, we will discuss the importance of optimizing insert geometry for improved chip evacuation in milling, and how the CNC Carbide Inserts process can be implemented.

Chip evacuation is a critical component of the milling process. When a piece of material is inserted into a milling machine, a cutting tool or insert is used to create the desired shape and size. The chips created by the cutting process need to be efficiently removed from the milling area in order to prevent damage to the cutting tool and the workpiece. Improper chip evacuation can result in poor surface finish, reduced tool life, and other problems.

Optimizing the geometry of the insert can significantly improve chip evacuation. Different inserts have different shapes and sizes that allow for more efficient removal of chips. For example, a pointed insert will create a larger chip that can be easily removed from the milling area. Additionally, the shape of the insert can be tailored to the material being machined to ensure that chips are efficiently removed. Optimizing the insert geometry will result in better chip evacuation and smoother surface finish.

To optimize the insert VCMT Insert geometry for improved chip evacuation, manufacturers must first identify the material and the type of insert being used. It is important to select an insert that is designed for the material being machined, in order to ensure the best possible performance. Additionally, manufacturers must consider the insert size, shape, and geometry to optimize chip evacuation. Smaller inserts generate smaller chips, which can be easily removed from the milling area. Additionally, inserts with a pointed end or other specialized shapes can be used to create larger chips and improve chip evacuation.

In conclusion, optimizing insert geometry is essential for improved chip evacuation in milling. By selecting the right insert and considering size, shape, and geometry, manufacturers can ensure that chips are efficiently removed from the milling area. This will result in higher quality parts and a more efficient manufacturing process.

Users of carbide inserts often fall into two distinct camps. On one side, there are those shops that are looking for a "universal" insert grade that will effectively handle a wide variety of applications, even if it means tolerating less than maximum metal removal rates in certain cases. The advantages are reduced tooling inventory, standardized programming routines, simplified setup procedures, among other sought-after benefits. Unfortunately, this universal insert grade is an elusive goal for cutting tool manufacturers, although considerable R&D efforts are still being devoted to this quest.

On the other side, there are those shops that strive to find the perfect match between the insert and the application, a match-up that will give them the highest possible metal removal rates, best surface finish, longest tool life, and so on. Maximum productivity and optimal results are what they're after. However, identifying that "perfect" insert hasn't always been easy or certain—the proliferation of insert grades and styles can be bewildering. And even if a shop can find the ideal solution, it has to maintain the machining conditions that allow the near-perfect insert to deliver its full potential, but shops haven't always had reliable information on what those conditions are.

As a matter of fact, most shops are caught somewhere in the middle of these two camps, being pulled in both directions at once.

But if you look at recent developments emerging from cutting tool manufacturers, the trend is decidedly toward the optimized insert. With today's understanding of the sophisticated factors and forces at work in a successful application, it is apparent that certain vendors are able to deliver an extremely productive solution for a very specific set of machining conditions. And they should be able to provide highly reliable information about using these tools to get the intended results.

Knowing something about the complex interactions of the critical components that unite to produce an optimized cutting system will help you understand why this systematized approach can be so effective. It will also help explain how vendors can guide you to the best insert with more confidence and certainty than ever before. Let's review some of the systems elements that an insert manufacturer has to work with and then look at how these elements can be engineered in combination to suit an application. In light of this discussion, you might find yourself reconsidering your approach to insert selection.

The Elements

Every successful cutting tool application represents a combination of:

a substrate,one or more coatings in most, but not all, cases,a chipbreaker, or "top form" geometry,a specific edge preparation,a specific style and nose radius,a toolholder, anda cutting fluid.

See Figure 1 (at right). A quick glance at any manufacturer's catalog will clearly demonstrate that the potential combinations of these elements run into the thousands, if not the millions.
Finding a way to make sense out of such a variety of choices is the major challenge facing both cutting tool producers and cutting tool consumers in the coming years. Material-based color codes and selection procedures built on them are a step in the right direction, but only a first step.

As insert systems become more and more application specific, new selection paradigms must be created to guide consumer choices. Regardless of the shape these may take, they must necessarily be grounded in a thorough understanding of the individual role of each of the seven elements, and of their interactions while in the cut.

The Substrate

In a coated insert, the substrate is the "foundation" for the cutting system, but it never actually comes into contact with the workpiece. This fact permits cutting tool manufacturers to tailor substrate properties over a much broader range than was possible when the uncoated substrate was the cutting tool.

Nearly all substrates are made from tungsten carbide (WC), which is still the only material available with the combination of hardness and toughness required to handle a broad range of cutting applications. Other materials such as ceramics and cermets provide a useful complement to WC at the high speed end of the application range, but these are rarely used with coatings.

The first substrates were simply traditional, straight WC grades that were coated to improve their performance. Some of these combinations proved so useful that they are still in production today.

Improved processing capabilities have led to the production of "enriched" substrates in which the cobalt content of a layer near the surface is significantly enhanced while the formation of cubic carbides is prevented. This provides substantially more edge strength than a straight grade substrate and is widely applied in inserts intended for roughing and interrupted cutting applications, as well as on some hard-to-machine materials.

A more recent development is the family of "fine grain" substrates in which the size of individual WC grains is controlled. These are primarily used in insert systems designed for machining very tough materials such as aerospace and high temperature alloys.

Finally, substrate performance can be "enhanced" by selectively adding other types of carbide to the straight WC mixture. The most common "alloys" consist of WC plus titanium carbide (TiC), tantalum carbide (TaC), vanadium carbide (VC), and niobium carbide (NbC), or some mixture of them. Each of these additional carbide materials produces specific properties that are useful in a range of common applications.

Substrate requirements vary from one workpiece material to another. Take steel as an example. Because of the continuous chip formation and the heat generated at the cutting tip, an insert requires a lot more deformation resistance as well as wear and crater resistance than a substrate required for, say, gray cast iron. That's because the cast iron does not generate as much heat, and the chips are more naturally broken anyway. Some of the cubic carbides, such as the TiC, TaC, NbC and VC, would be critical additions to a substrate designed for steel, but not as critical for gray cast iron.

For a gummy material like stainless steel, wear or crater resistance isn't as critical as toughness because of the build-up and chipping that is encountered. Consequently, a substrate resistant to chipping—one that contains less cubic carbide and is high in cobalt and has a finer grain—is better for stainless steels and high temperature alloys.

Coatings

There are two factors to be considered in evaluating insert coatings: the material or materials used, and the process by which they are applied. Both impact insert system performance.

The coating itself acts as the interface between the workpiece and the cutting tool. Depending on the application, coatings can provide wear resistance, abrasive and crater resistance, build-up edge resistance, chemical resistance, or a simple reduction in friction that lowers cutting temperatures. Figure 2 (at right) shows an example of coatings engineered for a specific application.

The most commonly used coating materials and the properties they provide are:

TiC: abrasive, flank and nose wear resistance,TiCN (titanium carbonitride): abrasive and some crater wear resistance,TiN (titanium nitride): some crater resistance, friction reduction, gold color, and a diffusion barrier,Al203 (aluminum oxide): crater and wear resistance, plus abrasive wear resistance at high cutting temperatures, andAl2O3/ZrO2 (aluminum oxide/zirconium oxide): best crater resistance, but softer than Al203.

There are four major coating technologies used in the cutting tool industry today. These are differentiated primarily by the temperature at which they operate. This is important because the coating temperature directly impacts substrate properties performance.

The most common coating technology is chemical vapor deposition, or CVD, which operates at a temperature of roughly 1,000°C. Nearly as common is physical vapor deposition, or PVD, which operates at the other end of the temperature spectrum in the 400°C range.

Between these two extremes are two other emerging coating processes that promise to enhance insert system performance. Plasma assisted chemical vapor deposition, or PCVD, is well accepted in Europe and is being explored in North America. PCVD operates in the 600°C range. Finally, medium temperature chemical vapor deposition, or MTCVD, is an emerging and promising technology that operates in the 800°C range.

The key factor to bear in mind is that the properties of both the coating and the substrate are changed by the application process. The same coating applied to the same substrate by different processes may in fact provide very different performance in the cut.

Different coatings are required for different materials. For example, it is critical to have a smooth coating—one that is more than simply wear- or crater-resistant—for hard-to-machine stainless steels and high temperature alloys. A smooth, thick coating is required when running steel and cast iron, too, because of the heat and wear. The PVD coating process produces a very smooth surface, while CVD coatings can be polished to achieve a smoother surface finish.

Coating thickness is critical for steel and cast iron because of the higher speeds at which they run. For high speeds, an oxide coating in combination with TiCN and proper thickness make an ideal combination. On the other hand, coating thickness is not as critical as smoothness for stainless steel and high temperature alloys.

Chipbreakers Or Top Form Geometries

With today's sophisticated insert shapes, the term "chipbreaker" no longer describes the contribution of this element to the insert systems. "Top form geometry" is a more precise term for the very complex shape seen on the cutting surface of a modern insert.

While chip control is still a major function, the top form geometry also serves to reduce cutting forces. Lower forces mean less heat, deformation and friction which enhance tool life and often improve workpiece size control and finish. Perhaps the best example of this is the use of "chipbreakers" on milling inserts. Generally speaking, milling chips tend to break themselves, but the other benefits of a well-engineered top form geometry are easily seen in reduced horsepower requirements and better parts. Many of today's high speed milling applications on relatively low horsepower machines would not be possible without effective top form geometries on the inserts.

Matching the chipbreaker to the application is very important. Valenite, a case in point, has 28 different chipbreakers for turning, some for roughing, some for general machining and some for finishing. Specialty geometries exist for certain metals, such as high temperature alloys and stainless steels. The Valenite SR chipbreaker is an example of this type of geometry. They are a positive-negative geometry, one with a small nose radius, perhaps only 0.004 inch. A very fine geometry is necessary to take very light cuts and control the chips in these types of materials.

Many shops think they don't need a chipbreaker for certain materials, such as gray cast iron and nodular cast iron, because the chips break on their own. These shops typically use flat top geometry for these materials because they have a lot of edge strength. However, we often recommend using a top form geometry for cast iron and nodular iron to reduce the cutting forces and minimize edge build-up.

Edge Preparation

In the past, most manufacturers offered only one or two standard edge preparations, or "hones," for any particular insert size and geometry. Today, however, it is recognized that the "hone" is really determined by the application for which the insert system is intended. An insert system intended for high speed finishing of steel has very different edge preparation requirements than one to be used for roughing, even though both may share the same basic geometry.

Ceramic and cermet materials also require edge preparation in the form of a "T-Land" geometry. Testing shows that very subtle variations in the width and angle of the "T-Land" can have substantial impact on tool life.

As a general rule, a heavier hone is necessary for continuous turning and milling of most steels and irons. Stainless steels and high temperature alloys, on the other hand, require a small hone or an up-sharp insert because of the build-up generated. Similarly, aluminum requires an up-sharp insert, also because of build-up. For cases involving a severe interrupted cut such as occurs in milling, a heavier hone or a "T-Land" is necessary.

Style And Nose Radius

Here, at least, conventional wisdom still prevails. Selecting a style with the greatest included angle will provide the strongest possible insert for the application. In general, a large nose radius provides better surface finish. These geometric factors, in conjunction with the toolholder, determine the effective lead angle, which impacts cutting force, and the resultant heat and wear that shorten tool life.

Not Just The Insert

Needless to say, it takes more than just the right insert to get optimum performance. The toolholder and the cutting fluid should also be considered part of the insert "system," even though these elements cannot be built in by the insert manufacturer.

In turning, the toolholder is the primary determinant of lead and rake angle, both of which can influence chip thickness, horsepower requirements, cutting forces and tool life. In milling the critical toolholder-related factors are radial and axial rake, which have the same effects found in turning applications.

Choice of cutting fluids is one of the most overlooked factors in the performance of any metalcutting application. See Figure 3 (at left). Recent testing has shown that the choice of cutting fluid can have a substantial influence on both insert life and cutting system performance, especially on hard-to-machine materials like stainless steels and high temperature alloys.

It is extremely important, therefore, to follow the insert manufacturer's advice and instructions regarding toolholder selection and cutting fluids. Because the systems approach relies on a synergy between all of the elements, all of them are essential to enjoying the full benefits of an optimized insert.

Direction Of The Future

Laboratory testing and field experience have clearly demonstrated that the very subtle interaction of the seven elements of an insert cutting system can have an extremely large impact on application performance. Clearly, the direction for the future is in matching insert cutting systems more and more specifically to workpiece materials and cutting operations. MMS

Simplifying Insert Selection

Today, we believe that 80 percent of all carbide used in machine shops across the United States is misapplied, whether using the correct insert but the wrong application, or vice versa. Cutting tool manufacturers have been working to solve this problem by developing various selection systems to guide users to the right insert for an application. A good selection system brings order and logic to insert use, and makes the growing range of insert choices a powerful resource for manufacturers.

The SpectraTurn Color System, from Valenite, shows how one selection system makes this happen for turning applications. The SpectraTurn Color System is incorporated into the company's SpectraTurn Application Guide.

This system breaks workpiece materials into three general color categories: the blue category contains carbon and alloy steels; the yellow category includes stainless steels, titanium, and high temperature alloys; and gray and ductile irons, aluminum, and non-ferrous materials are listed in the red category. The system then breaks down each general category into more specific groups of similar materials.

For a new application, the user needs to do the following steps to develop a successful application. In this illustration, let's assume that the user wants to perform a finishing operation on M1 tool steel.

Step 1: First, the user goes to the page where M1 tool steel is listed under the Tool Steels & Die Steels category of the blue section of the chart. From there, the user goes to the Blue Tungsten Steel Inserts (Steel) section on the following and looks at the Grade Selection Graph.

Here, the user goes down from the finishing area near the middle of the chart and sees that the center of the SV310 bar is closest to finishing. This is the recommended grade.

Step 2: The user goes to the nearby Blue Insert Application Guide and locates SV310 in the chart.

Step 3: Next, the user goes down the column under "F" for finishing, and comes to the recommended depth of cut (DOC), which is 0.020 to 0.070 inch. Next down the list is the recommended feed rate of 0.005 inch per revolution. Continuing down to the Tool Steels & Die Steels category (M1 tool steel falls into this category), we find the recommended chipbreaker—GF. Here, we also find the recommended speed of 600 sfm. So, we now have a complete recommendation for finishing M1 tool steel: use grade SV310 with an GF chipbreaker, Coated Inserts at a DOC from 0.020 to 0.070 inch, at a feed rate of 0.005 ipr and a speed of 600 SFM.

Whatever selection system you may work with, be sure to understand its underlying principles and follow the instructions carefully. As with any tool, wise use pays dividends.

Each of these additional carbide materials produces specific properties that are useful in a range of common applications.

Substrate requirements vary from one workpiece material to another. Take steel as an example. Because of the continuous chip formation and the heat generated at the cutting tip, an insert requires a lot more deformation resistance as well as wear and crater resistance than a substrate required for, say, gray cast iron. That's because the cast iron does not generate as much heat, and the chips are more naturally broken anyway. Some of the cubic carbides, such as the TiC, TaC, NbC and VC, would be critical additions to a substrate designed for steel, but not as critical for gray cast iron.

For a gummy material like stainless steel, wear or crater resistance isn't as critical as toughness because of the build-up and chipping that is encountered. Consequently, a substrate resistant to chipping—one that contains less cubic carbide and is high in cobalt and has a finer grain—is better for stainless steels and high temperature alloys.

Coatings

There are two factors to be considered in evaluating insert coatings: the material or materials used, and the process by which they are applied. Both impact insert system performance.

The coating itself acts as the interface between the workpiece and the cutting tool. Depending on the application, coatings can provide wear resistance, abrasive and crater resistance, build-up edge resistance, chemical resistance, or a simple reduction in friction that lowers cutting temperatures. Figure 2 (at right) shows an example of coatings engineered for a specific application.

The most commonly used coating materials and the properties they provide are:

TiC: abrasive, flank and nose wear resistance,TiCN (titanium carbonitride): abrasive and some crater wear resistance,TiN (titanium nitride): some crater resistance, friction reduction, gold color, and a diffusion barrier,Al203 (aluminum oxide): crater and wear resistance, plus abrasive wear resistance at high cutting temperatures, andAl2O3/ZrO2 (aluminum oxide/zirconium oxide): best crater resistance, but softer than Al203.

There are four major coating technologies used in the cutting tool industry today. These are differentiated primarily by the temperature at which they operate. This is important because the coating temperature directly impacts substrate properties performance.

The most common coating technology is chemical vapor deposition, or CVD, which operates at a temperature of roughly 1,000°C. Nearly as common is physical vapor deposition, or PVD, which operates at the other end of the temperature spectrum in the 400°C range.

Between these two extremes are two other emerging coating processes that promise to enhance insert system performance. Plasma assisted chemical vapor deposition, or PCVD, is well accepted in Europe and is being explored in North America. PCVD operates in the 600°C range. Finally, medium temperature chemical vapor deposition, or MTCVD, is an emerging and promising technology that operates in the 800°C range.

The key factor to bear in mind is that the properties of both the coating and the substrate are changed by the application process. The same coating applied to the same substrate by different processes may in fact provide very different performance in the cut.

Different coatings are required for different materials. For example, it is critical to have a smooth coating—one that is more than simply wear- or crater-resistant—for hard-to-machine stainless steels and high temperature alloys. A smooth, thick coating is required when running steel and cast iron, too, because of the heat and wear. The PVD coating process produces a very smooth surface, while CVD coatings can be polished to achieve a smoother surface finish.

Coating thickness is critical for steel and cast iron because of the higher speeds at which they run. For high speeds, an oxide coating in combination with TiCN and proper thickness make an ideal combination. On the other hand, coating thickness is not as critical as smoothness for stainless steel and high temperature alloys.

Chipbreakers Or Top Form Geometries

With today's sophisticated insert shapes, the term "chipbreaker" no longer describes the contribution of this element to the insert systems. "Top form geometry" is a more precise term for the very complex shape seen on the cutting surface of a modern insert.

While chip control is still a major function, the top form geometry also serves to reduce cutting forces. Lower forces mean less heat, deformation and friction which enhance tool life and often improve workpiece size control and finish. Perhaps the best example of this is the use of "chipbreakers" on milling inserts. Generally speaking, milling chips tend to break themselves, but the other benefits of a well-engineered top form geometry are easily seen in reduced horsepower requirements and better parts. Many of today's high speed milling applications on relatively low horsepower machines would not be possible without effective top form geometries on the inserts.

Matching the chipbreaker to the application is very important. Valenite, a case in point, has 28 different chipbreakers for turning, some for roughing, some for general machining and some for finishing. Specialty geometries exist for certain metals, such as high temperature alloys and stainless steels. The Valenite SR chipbreaker is an example of this type of geometry. They are a positive-negative geometry, one with a small nose radius, perhaps only 0.004 inch. A very fine geometry is necessary to take very light cuts and control the chips in these types of materials.

Many shops think they don't need a chipbreaker for certain materials, such as gray cast iron and nodular cast iron, because the chips break on their own. These shops typically use flat top geometry for these materials because they have a lot of edge strength. However, we often recommend using a top form geometry for cast iron and nodular iron to reduce the cutting forces and minimize edge build-up.

Edge Preparation

In the past, most manufacturers offered only one or two standard edge preparations, or "hones," for any particular insert size and geometry. Today, however, it is recognized that the "hone" is really determined by the application for which the insert system is intended. An insert system intended for high speed finishing of steel has very different edge preparation requirements than one to be used for roughing, even though both may share the same basic geometry.

Ceramic and cermet materials also require edge preparation in the form of a "T-Land" geometry. Testing shows that very subtle variations in the width and angle of the "T-Land" can have substantial impact on tool life.

As a general rule, a heavier hone is necessary for continuous turning and milling of most steels and irons. Stainless steels and high temperature alloys, on the other hand, require a small hone or an up-sharp insert because of the build-up generated. Similarly, aluminum requires an up-sharp insert, also because of build-up. For cases involving a severe interrupted cut such as occurs in milling, a heavier hone or a "T-Land" is necessary.

Style And Nose Radius

Here, at least, conventional wisdom still prevails. Selecting a style with the greatest included angle will provide the strongest possible insert for the application. In general, a large nose radius provides better surface finish. These geometric factors, in conjunction with the toolholder, determine the effective lead angle, which impacts cutting force, and the resultant heat and wear that shorten tool life.

Not Just The Insert

Needless to say, it takes more than just the right insert to get optimum performance. The toolholder and the cutting fluid should also be considered part of the insert "system," even though these elements cannot be built in by the insert manufacturer.

In turning, the toolholder is the primary determinant of lead and rake angle, both of which can influence chip thickness, horsepower requirements, cutting forces and tool life. In milling the critical toolholder-related factors are radial and axial rake, which have the same effects found in turning applications.

Choice of cutting fluids is one of the most overlooked factors in the performance of any metalcutting application. See Figure 3 (at left). Recent testing has shown that the choice of cutting fluid can have a substantial influence on both insert life and cutting system performance, especially on hard-to-machine materials like stainless steels and high temperature alloys.

It is extremely important, therefore, to follow the insert manufacturer's advice and instructions regarding toolholder selection and cutting fluids. Because the systems approach relies on a synergy between all of the elements, all of them are essential to enjoying the full benefits of an optimized insert.

Direction Of The Future

Laboratory testing and field experience have clearly demonstrated that the very subtle interaction of the seven elements of an insert cutting system can have an extremely large impact on application performance. Clearly, the direction for the future is in matching insert cutting systems more and more specifically to workpiece materials and cutting operations. MMS

Simplifying Insert Selection

Today, we believe that 80 percent of all carbide used in machine shops across the United States is misapplied, whether using the correct insert but the wrong application, or vice versa. Cutting tool manufacturers have been working to solve this problem by developing various selection systems to guide users to the right insert for an application. A good selection system brings order and logic to insert use, and makes the growing range of insert choices a powerful resource for manufacturers.

The SpectraTurn Color System, from Valenite, shows how one selection system makes this happen for turning applications. The SpectraTurn Color System is incorporated into the company's SpectraTurn Application Guide.

This system breaks workpiece materials into three general color categories: the blue category contains carbon and alloy steels; the yellow category includes stainless steels, titanium, and high temperature alloys; and gray and ductile irons, aluminum, and non-ferrous materials are listed in the red category. The system then breaks down each general category into more specific groups of similar materials.

For a new application, the user needs to do the following steps to develop a successful application. In this illustration, let's assume that the user wants to perform a finishing operation on M1 tool steel.

Step 1: First, the user goes to the page where M1 tool steel is listed under the Tool Steels & Die Steels category of the blue section of the chart. From there, the user goes to the Blue Tungsten Steel Inserts (Steel) section on the following and looks at the Grade Selection Graph.

Here, the user goes down from the finishing area near the middle of the chart and sees that the center of the SV310 bar is closest to finishing. This is the recommended grade.

Step 2: The user goes to the nearby Blue Insert Application Guide and locates SV310 in the chart.

Step 3: Next, the user goes down the column under "F" for finishing, and comes to the recommended depth of cut (DOC), which is 0.020 to 0.070 inch. Next down the list is the recommended feed rate of 0.005 inch per revolution. Continuing down to the Tool Steels & Die Steels category (M1 tool steel falls into this category), we find the recommended chipbreaker—GF. Here, we also find the recommended speed of 600 sfm. So, we now have a complete recommendation for finishing M1 tool steel: use grade SV310 with an GF chipbreaker, Coated Inserts at a DOC from 0.020 to 0.070 inch, at a feed rate of 0.005 ipr and a speed of 600 SFM.

Whatever selection system you may work with, be sure to understand its underlying principles and follow the instructions carefully. As with any tool, wise use pays dividends.

PreviousNext

Users of carbide inserts often fall into two distinct camps. On one side, there are those shops that are looking for a "universal" insert grade that will effectively handle a wide variety of applications, even if it means tolerating less than maximum metal removal rates in certain cases. The advantages are reduced tooling inventory, standardized programming routines, simplified setup procedures, among other sought-after benefits. Unfortunately, this universal insert grade is an elusive goal for cutting tool manufacturers, although considerable R&D efforts are still being devoted to this quest.

On the other side, there are those shops that strive to find the perfect match between the insert and the application, a match-up that will give them the highest possible metal removal rates, best surface finish, longest tool life, and so on. Maximum productivity and optimal results are what they're after. However, identifying that "perfect" insert hasn't always been easy or certain—the proliferation of insert grades and styles can be bewildering. And even if a shop can find the ideal solution, it has to maintain the machining conditions that allow the near-perfect insert to deliver its full potential, but shops haven't always had reliable information on what those conditions are.

As a matter of fact, most shops are caught somewhere in the middle of these two camps, being pulled in both directions at once.

But if you look at recent developments emerging from cutting tool manufacturers, the trend is decidedly toward the optimized insert. With today's understanding of the sophisticated factors and forces at work in a successful application, it is apparent that certain vendors are able to deliver an extremely productive solution for a very specific set of machining conditions. And they should be able to provide highly reliable information about using these tools to get the intended results.

Knowing something about the complex interactions of the critical components that unite to produce an optimized cutting system will help you understand why this systematized approach can be so effective. It will also help explain how vendors can guide you to the best insert with more confidence and certainty than ever before. Let's review some of the systems elements that an insert manufacturer has to work with and then look at how these elements can be engineered in combination to suit an application. In light of this discussion, you might find yourself reconsidering your approach to insert selection.

The Elements

Every successful cutting tool application represents a combination of:

a substrate,one or more coatings in most, but not all, cases,a chipbreaker, or "top form" geometry,a specific edge preparation,a specific style and nose radius,a toolholder, anda cutting fluid.

See Figure 1 (at right). A quick glance at any manufacturer's catalog will clearly demonstrate that the potential combinations of these elements run into the thousands, if not the millions.
Finding a way to make sense out of such a variety of choices is the major challenge facing both cutting tool producers and cutting tool consumers in the coming years. Material-based color codes and selection procedures built on them are a step in the right direction, but only a first step.

As insert systems become more and more application specific, new selection paradigms must be created to guide consumer choices. Regardless of the shape these may take, they must necessarily be grounded in a thorough understanding of the individual role of each of the seven elements, and of their interactions while in the cut.

The Substrate

In a coated insert, the substrate is the "foundation" for the cutting system, but it never actually comes into contact with the workpiece. This fact permits cutting tool manufacturers to tailor substrate properties over a much broader range than was possible when the uncoated substrate was the cutting tool.

Nearly all substrates are made from tungsten carbide (WC), which is still the only material available with the combination of hardness and toughness required to handle a broad range of cutting applications. Other materials such as ceramics and cermets provide a useful complement to WC at the high speed end of the application range, but these are rarely used with coatings.

The first substrates were simply traditional, straight WC grades that were coated to improve their performance. Some of these combinations proved so useful that they are still in production today.

Improved processing capabilities have led to the production of "enriched" substrates in which the cobalt content of a layer near the surface is significantly enhanced while the formation of cubic carbides is prevented. This provides substantially more edge strength than a straight grade substrate and is widely applied in inserts intended for roughing and interrupted cutting applications, as well as on some hard-to-machine materials.

A more recent development is the family of "fine grain" substrates in which the size of individual WC grains is controlled. These are primarily used in insert systems designed for machining very tough materials such as aerospace and high temperature alloys.

Finally, substrate performance can be "enhanced" by selectively adding other types of carbide to the straight WC mixture. The most common "alloys" consist of WC plus titanium carbide (TiC), tantalum carbide (TaC), vanadium carbide (VC), and niobium carbide (NbC), or some mixture of them. Each of these additional carbide materials produces specific properties that are useful in a range of common applications.

Substrate requirements vary from one workpiece material to another. Take steel as an example. Because of the continuous chip formation and the heat generated at the cutting tip, an insert requires a lot more deformation resistance as well as wear and crater resistance than a substrate required for, say, gray cast iron. That's because the cast iron does not generate as much heat, and the chips are more naturally broken anyway. Some of the cubic carbides, such as the TiC, TaC, NbC and VC, would be critical additions to a substrate designed for steel, but not as critical for gray cast iron.

For a gummy material like stainless steel, wear or crater resistance isn't as critical as toughness because of the build-up and chipping that is encountered. Consequently, a substrate resistant to chipping—one that contains less cubic carbide and is high in cobalt and has a finer grain—is better for stainless steels and high temperature alloys.

Coatings

There are two factors to be considered in evaluating insert coatings: the material or materials used, and the process by which they are applied. Both impact insert system performance.

The coating itself acts as the interface between the workpiece and the cutting tool. Depending on the application, coatings can provide wear resistance, abrasive and crater resistance, build-up edge resistance, chemical resistance, or a simple reduction in friction that lowers cutting temperatures. Figure 2 (at right) shows an example of coatings engineered for a specific application.

The most commonly used coating materials and the properties they provide are:

TiC: abrasive, flank and nose wear resistance,TiCN (titanium carbonitride): abrasive and some crater wear resistance,TiN (titanium nitride): some crater resistance, friction reduction, gold color, and a diffusion barrier,Al203 (aluminum oxide): crater and wear resistance, plus abrasive wear resistance at high cutting temperatures, andAl2O3/ZrO2 (aluminum oxide/zirconium oxide): best crater resistance, but softer than Al203.

There are four major coating technologies used in the cutting tool industry today. These are differentiated primarily by the temperature at which they operate. This is important because the coating temperature directly impacts substrate properties performance.

The most common coating technology is chemical vapor deposition, or CVD, which operates at a temperature of roughly 1,000°C. Nearly as common is physical vapor deposition, or PVD, which operates at the other end of the temperature spectrum in the 400°C range.

Finally, medium temperature chemical vapor deposition, or MTCVD, is an emerging and promising technology that operates in the 800°C range.

The key factor to bear in mind is that the properties of both the coating and the substrate are changed by the application process. The same coating applied to the same substrate by different processes may in fact provide very different performance in the cut.

Different coatings are required for different materials. For example, it is critical to have a smooth coating—one that is more than simply wear- or crater-resistant—for hard-to-machine stainless steels and high temperature alloys. A smooth, thick coating is required when running steel and cast iron, too, because of the heat and wear. The PVD coating process produces a very smooth surface, while CVD coatings can be polished to achieve a smoother surface finish.

Coating thickness is critical for steel and cast iron because of the higher speeds at which they run. For high speeds, an oxide coating in combination with TiCN and proper thickness make an ideal combination. On the other hand, coating thickness is not as critical as smoothness for stainless steel and high temperature alloys.

They are a positive-negative geometry, one with a small nose radius, perhaps only 0.004 inch.

Carbide Inserts： The Future of Sustainable and Eco_3

Computer Numerical Control, or CNC in brief, has revolutionized manufacturing. The technology has been developing for over 70 years, becoming the pillar for modern-day production and finding applications in producing end-use parts in every manufacturing sector.

CNC prototype machining is one area in which this technology has proven to be a boon. CNC machining prototype solutions are indispensable in every industry. Therefore, manufacturers often wonder about the best method to create prototypes of machined parts.

This article will explore what CNC prototype machining is and how it has impacted the business of manufacturing. It will also cover the pros and cons of CNC prototype machining and mention several tips to optimize the processes to create prototypes.

What is Prototype Machining?

Prototype machining or a prototyping process is where a manufacturer creates a small batch of the final part, with the intention of a production run later.

The purpose of the prototyping stage is to convey visual information about the final parts, find out how a digital design turns out physically, and determine the properties of the end product created.

Functional prototypes of new parts also enable the manufacturer to identify defects in the design and eliminate them before manufacturing large quantities of the final product. Eliminating any defects in the prototyping stage makes the production run more cost-effective.

Why Is CNC Machining Good For Prototyping Processes?

To say that CNC machining is good for the prototyping stage would be an understatement. It is the go-to technology whenever prototype machining processes are needed.

CNC technology uses computerized controls to monitor the movement of the cutting head and workpiece. This movement can be controlled in the slightest intervals, something impossible if you choose alternative prototyping processes.

CNC prototype machining starts by creating a 3D CAM model of the final product. Once the model is completed, it is converted into a CAD file. Unlike a Computer-Aided Manufacturing (CAM) file, a CAD file is understood directly by the CNC machines since it contains instructions for the machine on how to operate.

CAD files are converted to CAM files which contain the G Code and M code. The G code controls movement, and the M code relates to the general operation of the CNC machine, like coolant control.

What are the Advantages of CNC Prototype Machining?

When wondering whether to choose alternative prototyping processes or CNC machining centers for prototypes, consider these advantages of CNC machining:

Repeatability and Consistency

Unlike alternative prototype processes, a CNC prototype has a high degree of repeatability. This means that any finished product manufactured by CNC machining will be the exact replica of any other finished product that uses the same process.

Consistently producing identical products makes CNC suitable for prototype machining centers. Prototypes are supposed to be identical copies of the original design. This precise imitation is only possible with the low tolerances that CNC machining offers.

High Precision

Due to the high control over the movement of the cutting tools, CNC machining offers tight tolerances and high accuracy. These are essential in prototypes to make them fit for the original purpose. Additionally, since the machining process is accurate, manufacturers know that any flaws in the manufactured prototype result from the design, not the actual CNC prototyping stage.

Time-Saving Process

CNC prototype machining does not need any mold or time-consuming prerequisites. Therefore, it is a high-speed process. The ability to modify CAM/CAD files allows machining centers to make changes to the prototype, take it through CNC machining again, and have it back in no time.

Cost Effective

CNC prototype machining saves the manufacturer money in the long run. This is because any defects and errors can be rectified in a small prototype batch instead of troubleshooting defects in the large quantities of final parts produced in the production stage.

Additionally, future changes only need minor modifications to the CAD files instead of creating a new design from scratch.

Material Versatility

Unlike other manufacturing processes like 3D printing, CNC prototype machining can work with various highly machinable material options. These material options range from the strongest metals and alloys to materials like wood and plastics. Therefore, the prototyping process can be done using the same material as the Carbide Milling Inserts final part, which is a great advantage.

For example, there are not many methods capable of sheet-metal forming. This makes CNC machining an excellent choice for metal prototypes that need greater mechanical stability and don’t exhibit weakness.

Some of the material options that work well with CNC prototype machining services are:

• Aluminum
• Steel
• Stainless Steel
• ABS
• Magnesium
• Titanium
• Zinc
• Brass
• Bronze
• Copper
• Teflon
• Polycarbonates (PC)
• Polypropylene (PP)
• Polymethyl Methacrylate (PMMA)
• Polystyrene (PS)
• Polyoxymethylene (POM)
• PAGF
• PCGF
• Low-Density Polyethylene (LDPE)
• High-Density Polyethylene (HDPE)

Limitations Threading Inserts of Prototyping Processes With CNC Machined Parts

When it comes to prototyping, using the CNC method is the best way in most cases. However, despite its many advantages, other CNC characteristics might be considered cons. These cons include:

Subtractive Process

Prototype CNC machining is a subtractive process, so it creates the final part by removing material from the initial workpiece. This can lead to increased material usage compared to additive processes that work by adding material to a workpiece to create the final part. The machining centers incur higher material costs due to increased material usage.

Some Geometrical Restrictions

Since CNC prototype machining works from the outside in, some geometries cannot be manufactured using this process. This is especially true for the internal components of a prototype. Other manufacturing processes, like additive production, work from the inside out, so they are preferable for manufacturing internal geometries.

Technical Expertise

CNC prototype machining requires specific technical knowledge. The essential skill set includes making CAD files and operating the CNC machine.

More Expensive Than 3D Printing

Since manufacturers incur higher material costs, CNC prototype machining is more expensive than 3D printing. However, it is important to note that the added expense of CNC prototyping comes with greater accuracy and the ability to work on a wider range of materials.

In the case of other processes like 3D production, prototyping is limited to plastics like PLA. While PLA is considerably cheaper than metal blocks, its other characteristics don’t always fit the prototyping requirements.

Applications of CNC Machined Prototypes in the Industrial Manufacturing Process

CNC prototype machining is used in Research and Development in every sector. Some of the industries that rely on it heavily are:

Automotive Industry

CNC prototype machining is the go-to process for designing parts and models in the automotive industry. The automotive industry requires gears and parts with ultra-tight tolerances. CNC machining prototypes can fulfill this requirement, unlike many other methods.

Aerospace Industry

The aerospace industry constantly goes through CNC machining prototypes to test the performance of new innovations in parts and materials. These parts go in aircraft and monitoring equipment, so extreme care is needed to ensure they function optimally.

Architecture and Construction Industry

CNC machining is extensively used in architecture and construction for making interior and exterior elements. In the early days, the process was accomplished using injection molds which led to increased time and costs. However, CNC machining prototypes have made it faster and cheaper.

Medical Industry

The medical industry is evolving rapidly, with new medical equipment and prosthetics providing new possibilities for treatments. Medical equipment applications require microscopic precision and hard materials. The CNC machining process provides the highest quality for manufacturing functional prototypes for such equipment since other methods don’t have the required accuracy.

Military Industry

The military industry consumes a significant portion of the budget of any economy, and a big part goes toward Research & Development. Military R&D involves making new weapons, warfare vehicles, aircraft, and their constituent parts. Since most of these use metals or even harder materials, rapid prototyping is essential. CNC machining prototypes are used in every step of military R&D.

Oil & Energy Industry

The oil industry requires parts with high physical strength that can mine exceptional depths in the earth’s surface and extract the resources. These parts are crafted using CNC milling prototyping or other custom CNC machining methods. In energy industries, CNC prototypes are used to explore green energy resources that reduce environmental impact.

CNC Prototype Machining vs 3D Printing

Professionals often debate about the best prototyping method between two technologies – CNC machining and 3D printing. Here is an overview of the differences between the two technologies compared based on the factors that matter:

Working Principle

CNC machining is a subtractive manufacturing method. It takes a workpiece, removes unwanted material with a cutting tool, and shapes it into the final part. On the other hand, 3D printing is one of the additive processes. It works by starting from nothing and adding material a little at a time by melting and forming it into the final part.

Supported Materials

CNC machining supports various materials, from metals to wood and plastics. However, 3D printing is severely limited when it comes to materials supported. Its functionality is limited to making thermoplastic prototypes because this method works by reheating and shaping the material.

Possible Geometry

3D-printed parts can have complex internal geometries because these parts are made from the inside out. However, since CNC parts are produced by using a cutting tool on the outside. It cannot make functional prototypes with complex internal geometry.

Wastage

As a subtractive manufacturing method, CNC machining leads to much material wastage. However, the waste material costs can be recovered by selling recyclable waste material. In contrast, 3D prototyping has good material utilization because it’s an additive manufacturing technology.

Manufacturing Time

While 3D printing is called rapid prototyping, CNC machining is significantly faster. 3D-printed parts take many hours to manufacture a single piece. However, CNC machining can create a part in minutes or tens of parts in the same time frame as 3D.

Rapid Tooling: Injection Molded Prototypes via CNC Machining

Rapid tooling is a manufacturing technique that allows the quick production of machined tooling, such as dies and molds. This machined tooling is manufactured using CNC machining technology. The tooling is then used to form a prototype through an injection mold.

Rapid tooling differs from rapid prototyping, so the two should not be confused. Rapid tooling uses the advantages of CNC machining and injection molding while eliminating the disadvantages of each process. By creating machined tooling with CNC and the final part with an additive method like injection molding, manufacturers can save costs while retaining excellent precision.

Using a CNC machining service for prototyping leads to greater material costs. But using injection molding for prototypes takes longer, and it is challenging to replicate the exact part from the original design. Therefore rapid tools provide a midway between CNC prototyping and rapid manufacturing.

Tips For Preparing Quality CAD Models For Prototype CNC Machining Process

The final part quality of CNC machined prototyping can vary depending on the CAD file used. These designs convey visual information and provide critical dimensions for the components. Therefore, prototypes that require excellent part quality depend on a high-quality model. Here are some tips to prepare CAD models and drawings:

Optimizing Design Elements

Optimizing design elements such as cavities and holes is important when using CNC machines. For instance, in the case of end milling, the maximum depth obtained is three times the diameter of the tool. Therefore, specify and limit the dimensions of such cavities.

Ideal Wall Thickness

When creating drawings, be careful of the minimum wall thickness. Walls that are too thin can lead to the reduced mechanical stability of CNC custom parts and exhibit weakness. As a rule of thumb, the thickness of metal walls should always be greater than 0.8 mm. For plastic walls, the thickness should be greater than 1.5 mm.

Choosing the Right CAD Software

It’s understandable that the vast application of CAD in manufacturing has led to the emergence of many different CAD software for custom prototypes in various industries. While some are good, others can be unnecessarily complicated or too limited for some applications.

Therefore, choose the correct CAD applications for your particular sector. CAD software which is suitable for mechanical engineers and sheet metal forming might not be as good for architecture, and vice versa. Find the CAD software that fits your particular prototype needs.

Creating a Checklist

An initial checklist of the designs and features you want in prototypes is critical. Adding features while designing the CAD file is easier than trying to modify the file later.

Simplify Drawings

There are multiple ways to create a CAD design for the same prototype. Keep drawings simple to reduce unnecessary machining steps. For complicated parts, it is a good idea to split the drawing into two different parts that can be joined later.

Final Thoughts

Prototypes are an integral part of the manufacturing process because they save costs and avoid long-term issues. CNC machined prototypes are a great way to go ahead with the prototypes stage, providing fast and precise models.

Following the information provided in this article, it is possible to create high-quality prototypes. An important step is to use the tips provided for making perfect CAD design for rapid manufacturing, simple CNC machines, advanced CNC technology, or any other computer-aided manufacturing process.

Frequently Asked Questions

Here are the answers to some common questions that people have regarding CNC prototyping:

1. Is CNC prototyping machining the best option for prototyping?

CNC prototyping is the best option for prototypes when fast production, low tolerances, or material versatility are priorities. For low-budget and cost-effective prototyping using thermoplastic materials, 3D printing can be a viable option.

2. Which is cheaper: CNC machined prototypes or injection molded prototypes?

The molds used in injection molding make it more expensive than CNC machining. In large-scale production, the mold cost is divided over a large volume. But prototypes are small-volume production runs, making injection molding the costlier option. In contrast, the cost of CNC prototypes can be lowered by selling recyclable waste material. Doing so also reduces its environmental impact.

3. How much does CNC prototyping cost?

The cost of a CNC prototype can vary widely based on the particular requirements of the prototype. Generally, the cost starts at about $35 per hour for 3-axis CNC machines and can go up to $120 per hour for a prototype that requires a CNC machine with more cutting axes. The axes required will depend on the complexity of the prototype.

Computer Numerical Control, or CNC in brief, has revolutionized manufacturing. The technology has been developing for over 70 years, becoming the pillar for modern-day production and finding applications in producing end-use parts in every manufacturing sector.

CNC prototype machining is one area in which this technology has proven to be a boon. CNC machining prototype solutions are indispensable in every industry. Therefore, manufacturers often wonder about the best method to create prototypes of machined parts.

This article will explore what CNC prototype machining is and how it has impacted the business of manufacturing. It will also cover the pros and cons of CNC prototype machining and mention several tips to optimize the processes to create prototypes.

What is Prototype Machining?

Prototype machining or a prototyping process is where a manufacturer creates a small batch of the final part, with the intention of a production run later.

The purpose of the prototyping stage is to convey visual information about the final parts, find out how a digital design turns out physically, and determine the properties of the end product created.

Functional prototypes of new parts also enable the manufacturer to identify defects in the design and eliminate them before manufacturing large quantities of the final product. Eliminating any defects in the prototyping stage makes the production run more cost-effective.

Why Is CNC Machining Good For Prototyping Processes?

To say that CNC machining is good for the prototyping stage would be an understatement. It is the go-to technology whenever prototype machining processes are needed.

CNC technology uses computerized controls to monitor the movement of the cutting head and workpiece. This movement can be controlled in the slightest intervals, something impossible if you choose alternative prototyping processes.

CNC prototype machining starts by creating a 3D CAM model of the final product. Once the model is completed, it is converted into a CAD file. Unlike a Computer-Aided Manufacturing (CAM) file, a CAD file is understood directly by the CNC machines since it contains instructions for the machine on how to operate.

CAD files are converted to CAM files which contain the G Code and M code. The G code controls movement, and the M code relates to the general operation of the CNC machine, like coolant control.

What are the Advantages of CNC Prototype Machining?

When wondering whether to choose alternative prototyping processes or CNC machining centers for prototypes, consider these advantages of CNC machining:

Repeatability and Consistency

Unlike alternative prototype processes, a CNC prototype has a high degree of repeatability. This means that any finished product manufactured by CNC machining will be the exact replica of any other finished product that uses the same process.

Consistently producing identical products makes CNC suitable for prototype machining centers. Prototypes are supposed to be identical copies of the original design. This precise imitation is only possible with the low tolerances that CNC machining offers.

High Precision

Due to the high control over the movement of the cutting tools, CNC machining offers tight tolerances and high accuracy. These are essential in prototypes to make them fit for the original purpose. Additionally, since the machining process is accurate, manufacturers know that any flaws in the manufactured prototype result from the design, not the actual CNC prototyping stage.

Time-Saving Process

CNC prototype machining does not need any mold or time-consuming prerequisites. Therefore, it is a high-speed process. The ability to modify CAM/CAD files allows machining centers to make changes to the prototype, take it through CNC machining again, and have it back in no time.

Cost Effective

CNC prototype machining saves the manufacturer money in the long run. This is because any defects and errors can be rectified in a small prototype batch instead of troubleshooting defects in the large quantities of final parts produced in the production stage.

Additionally, future changes only need minor modifications to the CAD files instead of creating a new design from scratch.

Material Versatility

Unlike other manufacturing processes like 3D printing, CNC prototype machining can work with various highly machinable material options. These material options range from the strongest metals and alloys to materials like wood and plastics. Therefore, the prototyping process can be done using the same material as the Carbide Milling Inserts final part, which is a great advantage.

For example, there are not many methods capable of sheet-metal forming. This makes CNC machining an excellent choice for metal prototypes that need greater mechanical stability and don’t exhibit weakness.

Some of the material options that work well with CNC prototype machining services are:

• Aluminum
• Steel
• Stainless Steel
• ABS
• Magnesium
• Titanium
• Zinc
• Brass
• Bronze
• Copper
• Teflon
• Polycarbonates (PC)
• Polypropylene (PP)
• Polymethyl Methacrylate (PMMA)
• Polystyrene (PS)
• Polyoxymethylene (POM)
• PAGF
• PCGF
• Low-Density Polyethylene (LDPE)
• High-Density Polyethylene (HDPE)

Limitations Threading Inserts of Prototyping Processes With CNC Machined Parts

When it comes to prototyping, using the CNC method is the best way in most cases. However, despite its many advantages, other CNC characteristics might be considered cons. These cons include:

Subtractive Process

Prototype CNC machining is a subtractive process, so it creates the final part by removing material from the initial workpiece. This can lead to increased material usage compared to additive processes that work by adding material to a workpiece to create the final part. The machining centers incur higher material costs due to increased material usage.

Some Geometrical Restrictions

Since CNC prototype machining works from the outside in, some geometries cannot be manufactured using this process. This is especially true for the internal components of a prototype. Other manufacturing processes, like additive production, work from the inside out, so they are preferable for manufacturing internal geometries.

Technical Expertise

CNC prototype machining requires specific technical knowledge. The essential skill set includes making CAD files and operating the CNC machine.

More Expensive Than 3D Printing

Since manufacturers incur higher material costs, CNC prototype machining is more expensive than 3D printing. However, it is important to note that the added expense of CNC prototyping comes with greater accuracy and the ability to work on a wider range of materials.

In the case of other processes like 3D production, prototyping is limited to plastics like PLA. While PLA is considerably cheaper than metal blocks, its other characteristics don’t always fit the prototyping requirements.

Applications of CNC Machined Prototypes in the Industrial Manufacturing Process

CNC prototype machining is used in Research and Development in every sector. Some of the industries that rely on it heavily are:

Tracability is Paramount – Look for the License

All gaging equipment must be calibrated periodically to ensure that it is capable of measuring parts accurately. This is true for every hand tool or gage used in a manufacturing environment that verifies the quality of parts produced. This has always been necessary for maintaining quality, but there are also additional, external reasons to establish and maintain a regular program of gage calibration, mainly customer requirements. It is now common that companies request suppliers to document their quality efforts from start to finish.

Some large companies with thousands of hand measuring tools, dial/digital indicators and comparators can justify the cost of hiring or training specialists in gage calibration methods and supply them with equipment to perform in-house calibration. However, dial and digital indicator or comparator calibration can be a very time-consuming and operator-intensive process.

Example of points required for checking an indicator.

Most dial indicators are relatively short-range but need to be checked at multiple points throughout their range to verify performance accuracy. They then need to be checked again in the reverse direction to verify hysteresis requirements. Historically, most dial indicator calibrators have been built around a high-precision mechanical micrometer, in effect, turning the micrometer to a known point and then observing any deviation on the dial indicator. Even for a short-range indicator, the process will involve moving a mechanical dial calibrator by hand to 20 or more points along the indicator’s travel. This is not too difficult for a short-range indicator, but with a longer-range indicator, say 12.5, 25, 50 or even 100 mm of range, there are a lot of positions to go to and points to observe and record.

This can also take a significant amount of time and concentration by the user. Doing this for many indicators throughout the day is stressful for the operator not only in hand-positioning the micrometer head to hundreds if not thousands of points, but also the resulting eye strain from reading the micrometer head and the indicator. The reading is also problematic since people will naturally (unintentionally) reverse numbers or just misread. Alternatively, in the case of a dial indicator, not reading the indicator straight on causes a parallax effect and a misreading of the result.

In order to reduce operator stress and increase productivity, automated calibrators are available that, based on the indicator, will drive a precision spindle to the desired location. The operator can then read and record the deviations.  These machines will significantly reduce the hand/arm strain caused by the constant rotational driving of the micrometer head. This is a significant improvement. However, there are better options.

The real improvement would be to eliminate the operator by installing the indicator into a calibration tool, setting the parameters within the gage for the indicator, and then letting the gage measure and certify the indicator without operator involvement. This allows the Coated Inserts gage technician to be productive preparing the next indictor to be checked, signing the indicator certifications, or even starting another calibration process while the automated calibrator is working.

Systems can “read” the indicator to capture its values.

With today’s? modern vision systems, it is possible to “read” the dial/digital indicator or comparator. By read, I mean the vision system can actually know what the indicator and the dial should be and process an image to read the pointer relative to the graduations and interpolate this as a measurement. In the case of digital indicators, the digital dial is scanned by the system's camera, the digits are analyzed/“read” by the controller and the actual deviation between measurements is made.

Because of this WCMT Insert automation with image processing, what once was a labor-intensive process with a high risk of error is now faster. Also, it reduces uncertainties while preventing potential stress and injuries to the operator. With the auto-recognition of the vision system, more test items with more data points will be recorded faster than conventional, manual methods. This frees the operator to be productive during the automated measuring process.

All gaging equipment must be calibrated periodically to ensure that it is capable of measuring parts accurately. This is true for every hand tool or gage used in a manufacturing environment that verifies the quality of parts produced. This has always been necessary for maintaining quality, but there are also additional, external reasons to establish and maintain a regular program of gage calibration, mainly customer requirements. It is now common that companies request suppliers to document their quality efforts from start to finish.

Some large companies with thousands of hand measuring tools, dial/digital indicators and comparators can justify the cost of hiring or training specialists in gage calibration methods and supply them with equipment to perform in-house calibration. However, dial and digital indicator or comparator calibration can be a very time-consuming and operator-intensive process.

Example of points required for checking an indicator.

Most dial indicators are relatively short-range but need to be checked at multiple points throughout their range to verify performance accuracy. They then need to be checked again in the reverse direction to verify hysteresis requirements. Historically, most dial indicator calibrators have been built around a high-precision mechanical micrometer, in effect, turning the micrometer to a known point and then observing any deviation on the dial indicator. Even for a short-range indicator, the process will involve moving a mechanical dial calibrator by hand to 20 or more points along the indicator’s travel. This is not too difficult for a short-range indicator, but with a longer-range indicator, say 12.5, 25, 50 or even 100 mm of range, there are a lot of positions to go to and points to observe and record.

This can also take a significant amount of time and concentration by the user.

What is the APT programming language ？ Where is it used in CNC programming ？

Springs are mechanical components used in many products such as watches, automobiles, and cellphones. There are many types of springs, each with unique features making choosing difficult.

Therefore, there is a need to know about them. This article discusses the common spring types, their applications, materials and what causes a mechanical spring failure so that you can select the right one.

Hooke's Law: Understanding the Principle of Spring

Spring is a mechanical component that, when compressed by a load, stores the energy, and releases it when the load is removed. This is the normal way all springs function irrespective of their types, as expressed by Hooke’s law.

Hooke’s law relates the force exerted by a load on a spring and its elasticity. According to the law, the force exerted by a load needed to compress or extend a spring is directly proportional to the displacement, as expressed by the mathematical expression below: F=-kX
Where;
F=force exerted by the load on the spring
X=spring displacement (it is a negative value indicating the force to restore the spring is opposite the direction)
k=spring constant, which shows the spring stiffness and depends on the spring type

Types of springs and Their Uses

There are several types of springs used in different capacities. Generally, there are three main categories, and each category has its subcategories. Below are the properties of the different spring types and their applications.

Category One: Helical Springs

Helical springs have a general helix shape (hence the name) but different cross-sections. They are the most common types of springs in rapid prototyping and are widely applicable in product manufacturing. Below are the different types of helical springs.

Compression Springs

Compression springs are open coiled springs with a constant diameter and space between each coil. The springs are compressible only one way as they resist axial compression. These spring types are widely applicable in product manufacturing, such as valves and suspension.

Extension Springs

Extension springs are closed compression springs. They function by elongating during tension and storing energy. When on tension removal, the mechanical spring returns to its original shape dissipating the energy. Extension springs are an important part of garage doors, pull levers, jaw pliers, and weighing machines.

Torsion Springs

A torsion spring is attached to two components horizontally or vertically using their two ends. They function by storing and releasing rotational energy. The tighter the winding, the more energy the spring stores and releases on load removal. They are applicable in garage doors, watches, etc.

Spiral Springs

Spiral springs are rectangular metal strips made into a flat spiral that can store and release a reasonable amount of energy at a constant rate. Due to the constant release of energy, they Cermet Inserts are applicable in making mechanical watches, seat recliners, toys, etc.

Category Two: Leaf Springs

These spring types are from rectangular metal plates or leave bolted, clamped, and applicable in shock absorption in heavy vehicles. Below are the different leaf springs types.

Elliptical Leaf Spring

Elliptical leaf spring comprises two stacked, bolted, and clamped leaves with semi-elliptical shapes connected in opposite directions. Although they have opposite directions, there is no need for spring shackles due to the leaf’s subjection to the same amount of elongation on compression. These springs were important in old cars where car manufacturers attached them to the axle and frame. However, they are not much important nowadays.

Semi Elliptical Leaf Spring

Semi elliptical Tungsten Carbide Inserts leaf spring comes from steel leaves having the same width and thickness but different lengths. The longest/uppermost leave is the master leaf. They are the most popular leaf spring in automobiles as they require less maintenance and have a long life.

Semi elliptical leaf springs have an end fixed rigidly to the automobile frame and the other to the shackles. Therefore, the length varies when driving in rough terrains, aiding in shock absorption.

Quarter Elliptical Leaf Spring

Like the elliptical leaf spring, the quarter elliptical leaf spring is olden. Also known as the cantilever type of leaf spring, it has one end fixed on the frame side member using a U-clamp or I-bolt and the other freely connected to the axle. Therefore, when the front axle beams experience shocks, the leaves can easily straighten and absorb the shock.

Three-Quarter Elliptical Leaf Spring

This leaf spring is a combination of the quarter elliptical spring and semi-elliptical spring. On the one hand, the semi-elliptical ends are attached to the vehicle frame and the quarter elliptical spring. On the other hand, the free end of the quarter elliptical spring is then attached to the vehicle frame using an I-bolt.

Transverse Leaf Spring

These are semi-elliptical leaf springs mounted transversely along a vehicle width. In this arrangement, the longest leaf is at the bottom while the mid-portion is fixed to the frame using a U-bolt. Transverse leaf springs lead to rolling. Therefore, they have limited use in the automobile industry.

Category Three: Disk Springs

Disk springs are springs with conical shapes and flexible effects. Consequently, they are applicable in limited space. Below are the types of disk springs.

Belleville Disk Spring

Belleville disk spring or coned-shaped disk spring has a cupped construction. Therefore, they don’t lie flat. They can compress and handle heavy loads. Therefore, they are applicable to products used in high-stress conditions.

Curved Disk Spring

Curved disk springs or crescent washers function by applying light pressure to the mating pair. Therefore, they can resist loosening due to vibration. They are applicable in products that use threaded bolts, fasteners, screws, and nuts in machines which high and constant vibration.

Slotted Disk Spring

Slotted disk springs have slots on the outer and inner diameter. Therefore, they reduce spring load and increase deflection. They are widely applicable in automatic transmissions, clutches, and overload couplings.

Wave Disk Springs

Wave disk springs look like architectural projects with their multiple waves per turn. Consequently, they are applicable in predictable loading as they can act as a cushion by absorbing stress when compressed axially.

Functions of Springs

Springs are an important part of many industrial products. Below are a few functions of springs and subsequent applications.

Shock Absorbing Properties

Springs can compress and extend due to applied load/force. Therefore, they have good shock absorbing capability. This use of springs is very important in the automobile industry as when a vehicle experiences a shock, the spring compresses to absorb the shock. It then releases the energy constantly.

Storage and Output Energy

Springs can store mechanical energy and release it constantly. Therefore, they can serve as an alternative to batteries in some devices. An important example is a mechanical watch and gun bolt.

Control the Movement of the Mechanism

Springs can control the movement of some components. Consequently, they are widely applicable in garages, doors, weighing machines, internal combustion engine valve springs, and control springs in clutches.

Vibration Damping

Springs also help in buffering or damping vibration. Therefore, they are important in making stable products in vibrating environments. Application of mechanical springs for vibration damping include cars and train cars.

Types of Materials Used in Making Springs

Springs comes from different material made using innovative processes. Below are a few examples of materials used and their importance.

Springs comes from different material made using innovative processes. Below are a few examples of materials used and their importance.

1. Low-Alloy Steel

Low-alloy steels contain nickel or molybdenum, making them superior to carbon steel. Springs made from these materials have the following properties:

• High heat resistance properties make them suitable for working in a machine that uses or generates high heat.
• High compressive strength, allowing them to last longer under axial stress.
• The addition of chromium, molybdenum, and nickel increases the spring’s creep strength and corrosion resistance.

2. Cold Drawn Wire

The cold drawn wire comes from work hardening, which improves the basic crystalline structure of the material. Therefore, springs made from cold-drawn wire have greater tensile strength, stress tolerance, and temperature tolerance.

3. Oil Tempered Spring Wire

Oil tempered wires have high resistance to fatigue, heat, and permanent set-in fatigue. Therefore, oil tempered springs wire is common in the automotive industry. They are also applicable in making products that use suspensions.

4. Bainite Hardened Strip

Bainite hardened strip comes from heat treating steel. Therefore, springs made from bainite hardened steel have great strength and fatigue resistance.

5. Stainless Spring Steel

Stainless steel contains chromium, nickel, magnesium, and even carbon. Springs made from stainless steel have great yield strength, corrosion resistance, and heat resistance. Therefore, they are applicable in washers, lock picks, and antennae.

6. Copper and Titanium

Copper or titanium alloy are anti-corrosive, heat resistant, strong, and durable. Therefore, copper and titanium springs are majorly torsion springs used in day-to-day door hinges, retractable seas, and some medical equipment.

Common Manufacturing Process of Types of Springs

Springs are made using a process of winding, heat treating, grinding, coating, and finishing option. The process is straightforward, although there are few variations depending on the types of springs.

1. Winding

The operator feeds the spring wire into a CNC machining or mechanical spring machine, straightening it. It then coils, forms, or bends the straightened wire to the desired shape. These processes can also be individual or in combination.

-Coiling involves using a spring coiler or CNC spring coiler machine to coil the straightened wire according to the desired coil. Coiling is applicable in making compression, extension, and torsion springs.
-Forming involves using a spring coiler or CNC spring former, which uses several bends, hoops, and radii to create several spring shapes. Forming is applicable in making extension springs, torsion springs, and wire forms

Springs are mechanical components used in many products such as watches, automobiles, and cellphones. There are many types of springs, each with unique features making choosing difficult.

Therefore, there is a need to know about them. This article discusses the common spring types, their applications, materials and what causes a mechanical spring failure so that you can select the right one.

Hooke's Law: Understanding the Principle of Spring

Spring is a mechanical component that, when compressed by a load, stores the energy, and releases it when the load is removed. This is the normal way all springs function irrespective of their types, as expressed by Hooke’s law.

Hooke’s law relates the force exerted by a load on a spring and its elasticity. According to the law, the force exerted by a load needed to compress or extend a spring is directly proportional to the displacement, as expressed by the mathematical expression below: F=-kX
Where;
F=force exerted by the load on the spring
X=spring displacement (it is a negative value indicating the force to restore the spring is opposite the direction)
k=spring constant, which shows the spring stiffness and depends on the spring type

Types of springs and Their Uses

There are several types of springs used in different capacities. Generally, there are three main categories, and each category has its subcategories. Below are the properties of the different spring types and their applications.
