The work is supported by various methods on the work table and may be fed to the cutter, longitudinally, transversely or vertically.1.

A milling machine is a machine tool in which metal is removed by means of a revolving cutter with many teeth, each tooth having a cutting edge which removes metal from a workpiece.The motion of the cutting tool is based on the Whitworth Quick return mechanism.In the shaper mechanism, tool feed is given by Ratchet and Pawl mechanism. It is common to obtain unidirectional cyclic rotation by means of a Ratchet mechanism.In the shaper, the cutting tool has a reciprocating motion and it cuts only during the forward stroke only. The work is held in a vice bolted to the work table.A shaper is used to generate flat (plane) surfaces by means of a single-point cutting tool similar to a lathe tool.Shaper is a reciprocating type of machine tool in which the ram moves the cutting tool backward and forwards in a straight line.A lathe is used for many operations such as turning, threading, facing, grooving, Knurling, Chamfering, centre drilling etc.
