A Comprehensive Guide to 5 Cutting Technologies in CNC Machining

Cutting Technologies in CNC Machining allows machinists to produce products with excellent precision and well-defined, combined with support from computer numerical control software.

However, CNC is not just one single method. It’s an umbrella term that encompasses a variety of cutting techniques.

Let’s find out the way all of these technologies work, their pros and cons, and more with TDB Tech!


5 Cutting Techniques in CNC Machining and Their Advantages

Though computer numerical coding is typically used to operate tools in CNC machining, its applicability will vary depending on the types involved.

Matching with cutting implements and tools, CNC techniques allow systems to limit common mistakes that are easily identified, diagnosed, and generally excusable by humans in their designs.

Furthermore, CNC can create a highly sophisticated process that achieves the greatest outcome.

However, for those who have never taken a look at CNC technology before, choosing the right cutting technology is a matter of understanding the risk, benefits, and details of the various options. Since some of them work best for complex projects while others show their superior qualities in putting the final touches. 

Here are the five most common CNC machining techniques in use today.

1. Milling 

One of the two most popular kinds of metal machining tools is a mill (beside turn). The workpiece is typically moved slowly while the tool rotates quickly in mills. 

This process differs from lathes, which move the tool slowly while the workpiece rotates quickly in place, making them ideal for creating cylindrical shapes such as driveshafts. 

In this method, materials are cut and shaped using rotating tools with multiple points. In this case, the milling tool feeds the workpiece rather than the other way around.

Pros: Milling can remove a large amount of material at once and offers excellent control over material cutting.

Cons: Requiring fully trained operators to supervise since CNC programming in milling machines is very complicated.

2. Turning – TDB Tech

CNC turning, or lathing is a common technique for producing components having the form of a cylinder. A lathe is a machine that holds a workpiece and rotates it while a stationary tool trims away excess material.

Nowadays, contemporary multi-axis CNC turning centers, which are fitted with CNC milling tools, can fabricate perfectly non-cylindrical parts as well.

Pros: Ideally for high-volume manufacturing when mass products are required.

Cons: Shapes are typically limited to three-dimensional shapes with curved surfaces, such as spheres and cones.

3. Electrical discharge machining (EDM) 

Electrical discharge machining, or EDM, can melt and shape metal with only electric sparks without the need to cut a piece. EDM is the newest metal processing technique, compared to rotating cutters and shearing.

Here are some of the significant characteristics of using rapidly pulsed high-voltage electrical discharges for machining:

High accuracy: The sparks can be focused on a very small area, which allows for high-precision machining.

Low cost: The process does not require the use of cutting fluids or coolants, which can save money.

Environmentally friendly: The process does not produce any harmful emissions, which makes it environmentally friendly.

Overall, rapidly pulsed high-voltage electrical discharges are a versatile and efficient machining process that can be used to cut and machine a wide variety of materials

Pros: EDM is perfectly suitable for fragile material, which can not bear heavy cutting.

Cons: This is a lengthy process that is mainly designed for finishing touches, not complete projects.

4. Grinding 

Grinding is a cutting technology, which includes a versatile machining process that can be used to shape, finish, and sharpen a wide variety of materials. It is often used to remove burrs, deburr, and sharpen edges. Grinding can also be used to create complex shapes and profiles.

Pros: This process can create the finest surface, making it ideal as a finishing tool.

Cons: This process is abrasing, which means it removes material by grinding. This makes it a slow process.

5. Drilling – Cutting Technologies in CNC Machining

CNC drilling is a process that uses a drill to create precise holes in a workpiece. The drill removes material by rotating and cutting, leaving behind a smooth, round hole.

Pros: Drilling is a relatively inexpensive and straightforward CNC machining process.

Cons: The ability to change drill bits as needed is essential for many applications. Without a tool turret, the application may be limited.

In addition to the five categories of Cutting Technologies CNC machining listed above, each category may have its own subcategories of tools that are useful for various parts of new product development.

As a result, operators must work with partners who are experienced in all the various applications of Cutting Technologies CNC machining in order to get the best possible results.
