Planer Shaping Machine

In a shaper machine work is held stationary and the cutting tool on the ram is moved back and forth across the work. In a planar machine, the tool is stationary and work piece travels back and forth under the tool. Shaper can be used for shaping much smaller jobs. ... Shaper uses one cutting tool at a time.

A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece. A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves.
