Milling is the process of creating machined surfaces by removing material with the use of a milling machine equipped with a rotating tool called a milling cutter (or simply "cutter").  

In milling, removal of material (in the form of chips) is the result of two motions: rotation of the cutting tool and advancing (or feeding) of the workpiece.   

Milling machines are particularly useful for machining prismatic parts.

Main milling operations

  • Peripheral milling (or slab milling)
  • Face milling (the most common type)
  • Straddle milling (peripheral and face combined)

Milling methods:

  • Conventional milling: the workpiece is fed in the direction opposite the rotation of the milling cutter.
  • In-cut milling (or climb milling): the workpiece is fed in the same direction as the rotation of the milling cutter.

Today’s milling machines are often automated (i.e. numerically controlled milling machines and machining centers). This means they are controlled electronically via a computer interface. In industry, qualified milling machine operators often carry out a variety of related tasks.
