CNC (Computer Numerical Control) lathes are automated machine tools that rotate a workpiece against a cutting tool to remove material and produce a desired shape. The process is controlled by a computer, allowing for high precision and repeatability in manufacturing.

Processes Involved in CNC Lathing

1. Turning: The primary operation where the workpiece is rotated, and the cutting tool moves along its length, removing material to achieve the desired diameter and shape.
2. Facing: A process for creating a flat surface on the end of the workpiece. The cutting tool moves perpendicular to the axis of rotation.
3. Drilling: CNC lathes can also incorporate drilling operations where hole features are created in the workpiece.
4. Boring: Enlarging an existing hole with a rotating cutting tool.
5. Threading: Creating screw threads on the surface of the workpiece, either internal or external.
6. Grooving: Cutting narrow grooves or channels into the workpiece.
7. Contour Turning: Producing complex shapes or profiles along the length of the workpiece.
8. Parting Off: Cutting the finished part from the remaining material at the end of the operation.
