Gear Skiving of Involute Internal Spur Gear : (Part 1. On the Tooth Profile)
Bulletin of JSME, 1974 Internal gears have disadvantages that fewer machine tools can produce them. The most commonly used techinique to produce internal gears is a gear shaping with pinion-type cutter which generates gear flanks with rotating motion and removes chips by reciprocating action. Hobbing and rack shaping are impractical on internal gears.
