[CNC Turning] What are the types of turning operations

In this article, we will talk about the types of operations of turning. Turning is the most basic machining process, as described in the previous article - [CNC Turning] Fundamental introduction on CNC turning theory. That is, the part is rotated while a single point cutting tool is moved parallel to the axis of rotation. Turning can be processed on the external surface of the part as well as internally, which is also called boring. The material used for this production is generally a work piece generated by other processes, such as casting, forging, extrusion or drawing.

The turning processes are typically carried out on a lathe, considered to be the oldest machine tools, and can be of four different types such as straight turning, taper turning, profiling or external grooving. Those types of turning processes can produce various shapes of materials such as straight, conical, curved, or grooved workpiece. In general, turning uses simple single-point cutting tools. Each group of workpiece materials has an optimum set of tools angles which have been developed through the years.
