ABSTRACT:
A shaving cutter having a circular array of teeth of the same number and approximate size as that of a gear to be shaved, and having cutting edges at one end of the teeth of identical profile as that to be formed on the gear teeth, the teeth of the cutter being backed off to provide cutting clearance and dimensioned to be received simultaneously in all of the tooth spaces of the gear with circumferential clearance. Relative reciprocation is provided with timed relative circumferential depth feed to shave first one side and then the other of the gear teeth. The teeth are provided with cutting edges occupying different planes to avoid having all teeth initiate cutting action at the same time.
