Shaper and planer are very old machine tools. They are used to produce a plane surface, inclined surface, and slots. But due to consumption of excess time, they are replaced by milling machines in large production. In shaper, cutting tool is provided reciprocation motion and job is provided only feed motion. Normally, forward stroke is cutting stroke and backward or reverse stroke is idle stroke. During the backward stroke, job is given feed motion. In planer, table, i.e., job is given reciprocating motion and tool is given feed motion. Planer is most suitable for the larger job which cannot be accommodated on shaper.
