Milling is the procedure of machining making use of rotary cutters in order to remove material[1] by improving a cutter in to a workpiece. This may possibly be done various direction[2] on one or even several axes, cutter machine head speed, in addition to pressure.[3] Milling covers numerous different procedures in addition to machines, on weighing scales from small person parts to big, heavy-duty gang milling operations. It is usually the most commonly utilized processes for engineering custom parts in order to precise tolerances.

Milling can be completed with a wide variety of device tools. The authentic class of device tools for milling was the milling machine (often identified as mill). Right after the creation of personal computer numerical control (CNC) in the sixties, milling machines progressed into machining facilities: milling machines increased by automated application changers, tool mags or carousels, COMPUTER NUMERICAL CONTROL capability, coolant techniques, and enclosures. Milling centers are typically classified as up and down machining centers (VMCs) or horizontal engineering centers (HMCs).

The particular integration of milling into turning conditions, and vice versa, started with survive tooling for lathes as well as the occasional utilization of mills for switching operations. This directed to a brand new course of machine equipment, multitasking machines (MTMs), which are purpose-built to facilitate milling and turning inside the same work package.
