The gear hobbing is process uses a conical cutter. During manufacturing both the cutter and the workpiece rotates with the cutter revolving around the gear blank. This process is suitable to make spur gears, worm gears, sprockets, and pinions.

Hobbing is more accurate the machined gears but less accurate than grinding. It is suited for high volume lower mix production
The gear shaping is a process that uses a cutter made to the geometric profile of the gear. The reciprocating motion of the cutter and the rotation of workpiece creates the desired gear shape. Helical gears, internal gears, and spur gears can all be manufacturing using gear shaping.
