Gear shaping

This method of gear cutting is based on the principle that any two gears will mesh if they are of the same pitch, proper helix angle, and proper tooth depth and thickness.

The process of gear shaping uses a toothed disk cutter which reciprocates in axial rotations.

The workpiece (or blank gear) rotates on a second shaft (spindle).

If a two-step process is used, all tooth spaces are partially cut before finishing.

The machine used for gear shaping generally consists of a base, column spindle, and an arbor.
