    Process. Milling is a cutting process that uses a milling cutter to remove material from the surface of a workpiece. The milling cutter is a rotary cutting tool often with multiple cutting points.As opposed to drilling where the tool is advanced along its rotation axis the cutter in milling is usually moved perpendicular to its axis so that cutting occurs on the circumference of the cutter.
