Gear shaping is a multipoint machining process for generating teeth by a reciprocating cutter. Gear shaping is one of the most versatile of all gear cutting operations. This cutting process uses a gear-shaped cutter that is reciprocated and rotated, in relationship to a blank, to produce the gear teeth. Cutters rotate in timed relationship with the workpiece. Finally Gear Shaping produces internal gears, external gears, and integral gear-pinion arrangements.
