Machining, also referred to as subtractive manufacturing, is the process of shaping or modifying a raw piece of metal material by controlled removal of material until it is in the desired shape requested by the customer.

Most modern-day machining is carried out by computer numerical control (CNC), in which a machine equipped with computers is used to control the movement and operation of mills, lathes or other cutting tools to perform the shaping. This automation increases efficiency, cuts down on human labor costs, while also increasing productivity.

CNC Machining

Primary Types of Machining:

There are three principal machining processes: turning, drilling and milling. Other operations falling into miscellaneous categories include shaping, planing, boring, broaching and sawing.

  • Turning is the machining process where the cutting tool is stationary, and the workpiece is rotated against the cutting tool to generate a desired cylindrical shape. Lathes are the principal machine tool used in turning operations.
  • Milling is the machining process where the workpiece is stationary the cutting tool is rotated against the workpiece to refine the piece and generate a plane or straight surface. Milling machines are the principal machine tool used in milling operations.
  • Drilling is the machining process used to create a round hole. The cutting tool typically has two or four helical cutting edges that rotate into the workpiece to produce or refine holes. Drilling operations are primarily performed in drill presses but occasionally on lathes or mills.
