Mechanical Milling Introduction Mechanical Milling Introduction Oct 21 2009 · Introduction Milling is the cutting operation that removes metal by feeding the work against a rotating cutter having single or multiple cutting edges Flat or curved surfaces of many shapes can be machined by milling with good finish and accuracy.

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
