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.
The lathe is a machine tool, which removes the metal from a piece of work to give the required shape and size.This is accomplished by holding the work securely and rigidly on the machine and then turning it against cutting tool, which will remove metal from the work in the form of chips. To cut the material properly, the tool should be harder than the material of the work piece.
