Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.

It is important to note that the piece has to be worked in a single machine cycle for it to be classified under this category of milling methods. String milling is quite similar to single piece milling but the only difference being that instead of a single piece there are several parts which is simultaneously fixed and are worked upon.
