The CNC machining industry has made great progress. In the design and use of CNC machine tools, different machine tool manufacturers use various user interfaces, but most of these systems are based on the same principle because CNC machine tools are programmed to perform functions similar to the products to be manufactured.

CNC machine tools are complex metal processing tools, which can produce complex parts required by modern technology. With the development of computer technology, numerical control has developed rapidly. It can be used in production equipment such as lathes, milling machines, drilling machines, laser cutting machines, abrasive jet cutting machines, punches, and so on.

The function of the CNC lathe

Although CNC lathes are mainly limited to cylindrical and conical shapes, they do have several machining processes that can be applied. CNC lathes can perform some special customized processing:

1. Knurling: the process of stamping diamond or straight-line patterns onto the surface of metal components. This impression is accomplished by coating the surface with a specially shaped and hardened metal wheel. The result is a better grip surface on the finished part.

2. Drilling: it will produce holes in the workpiece. A CNC milling machine or CNC drill bit can be used. However, if this is the only other operation required to complete a part formed on a lathe, it will be more cost-effective to drill in place and then use one of the following steps; drill, ream, or tap to complete the project.

3. Boring: a hole is enlarged and trimmed by removing material from the inner surface using a single-point cutting tool. Drilling is usually not an accurate method for placing holes, so it is necessary to drill a smaller hole during boring, and then enlarge and trim it.

4. Dumpling hole: it is an operation used only when it is necessary to finish the surface of the drilled area. If the diameter of the drilled hole is within 0.004 to 0.012 inches of its finished size, it may be necessary to use the final hole-making step to bring the part to specification.

5. Tapping is an operation used to add threads to pre-existing holes. Like initial drilling, this can also be done on a CNC milling machine, but it may be more cost-effective if this is the only additional physical feature to be added.

6. Eccentric turning: refers to the hole with multiple offset axes in the part. The crankshaft and camshaft are examples of this technique.

7. Chamfering will produce sloping edges on the workpiece. The inclined plane can soften the side of the part produced by the face and can facilitate the assembly of the mating parts.

The function of the CNC milling machine

Generally, the configuration of the milling machine is 3-axis to 6-axis. On the CNC milling machine, parts will be processed with the help of multi-point milling cutters. CNC milling machine is used for punching, punching, and slotting on the workpiece, and its application can also be found in spur gear manufacturing.

CNC milling machines are considered to be more accurate and versatile than CNC lathes and can perform many different operations. If the hole created by the required workpiece is greater than 1.5mm and the depth is less than four times its diameter, it can be drilled on the milling machine.

1. Slot cutting: generally, side and end cutters are used to cut grooves so that the material can be opened or closed in any length, width, and depth allowed. We can also use notch cutting to create a cavity or non-circular cut on the material surface.

2. Tool retraction: a groove or gap will be cut at the edge of the part to attract visual effects.

3. Sculpture: it is the art of carving design onto the surface. A CNC milling machine capable of engraving from a serial number to elaborate art decor.
