Description
Gear shaper is the machine tool for cutting the teeth of internal
or external gears. The name shaper relates to the fact that the
cutter engages the part on the forward stroke and pulls away from
the part on the return stroke, just like the clapper box on a
planer shaper.
The cutting tool is also gear shaped having the same pitch as the
gear to be cut. However number of cutting teeth must be less than
that of the gear to be cut for internal gears. For external gears
the number of teeth on the cutter is limited only by the size of
the shaping machine. For larger gears the blank is sometimes gashed
to the rough shape to make shaping easier.
