Understand various forming processes of metal materials (III): Machining

3、 Machining

Machining: it refers to the machining process in which the thickness of excess metal layer is directly cut off on the blank with a tool in the production process of parts, so as to meet the technical requirements of dimensional accuracy, mutual accuracy of shape and position, surface quality and so on.

Common machining methods: Turning, milling, planing, drilling, boring, grinding, gear machining, NC machining.
