CNC Turning is a fundamental subtractive manufacturing process in which excess material is removed through the combination of two primary motions: the rotational motion of the workpiece (primary cutting motion) and the translational motion of the cutting tool (feed motion). The workpiece is clamped in a spindle chuck and rotates at a specified angular speed, while a single-point cutting tool (typically featuring an indexable carbide insert) translates parallel, perpendicular, or inclined relative to the rotational axis.
The cutting process relies on localized plastic deformation of the material at the tool-workpiece interface. This process is divided into three distinct physical zones:
