The process of CNC turning

As is the case with other forms of CNC machining, the process starts with designing the card model. Afterward, the machines have to be prepared and the instructions fed through G-code. From there, the CNC turning process can begin.

The turning process is generally carried out in a delicate turning workshop. The lathes applied in the process can either be horizontal or vertical. This depends on the weight and tolerance range of the machined workpiece.

In CNC turning, the material (workpiece) is placed on a chuck. The chuck rotates at a specific RPM. Simultaneously, the tool is fed into the workpiece to remove materials continuously until the desired shape is accomplished.

A component is known as the turret with accessory tools usually is programmed to move the stock bar. As this happens, the material is removed, and the programmed result is achieved.

CNC turning is quite similar to CNC milling because they are both subtractive methods of manufacturing. However, the primary differentiating factor between the two is that the workpiece stays stationary in CNC milling as the cutting tools move. In CNC turning, the cutting tools remain in position as the workpiece rotates.

Forms of CNC turning

Below are some of the most popular forms of CNC turning:

a. Tapered turning

This process is where a conical surface is created by incremental reduction. The desired product shape or design can also be achieved by increasing the diameter of the workpiece from one part to the next. This form of CNC turning is mainly applied in external or internal machine constructions.

b. Hard turning

This is a CNC turning process where a workpiece is harder than 45 HRC. This form of CNC turning is mainly performed after the piece is treated through heat. The method is also used for grinding operations.

c. Face turning

This process involves removing materials from a workpiece by bringing the cutting tool to an appropriate rotating angle. It is an ideal method for creating flat surfaces. However, a 4-jaw chuck can be applied in face turning to make different shapes, like non-cylindrical shapes.

d. Spherical turning

This is where a spherical or ball-shaped surface is made on a workpiece. It is done through the gradual reduction of material from the workpiece. Note, spherical turning is primarily applied for making equipment like gears, hydraulic components, and injections.

e. Boring

This is the process of widening a drilled hope in a workpiece by subtracting material through a single-point cutting bit. It is primarily used for cutting holes with accurate dimensions and tapered holes on materials like pipes.

Conclusion

Other forms of CNC turning are; knurling, drilling, grooving, and parting. They are all quite different, but they apply the essential elements of CNC turning.
