ABSTRACT:
A method for machining a clutch gear for the transmission of an automobile which comprises forming a generally round annular bar made of malleable material in a cold forging or hot forging, urging the generally round annular bar against a die to form a final predetermined dimensional cross section and a chamfer projection simultaneously, fine blanking the chamfer projection into a tooth form and pushing the tooth form into a die from an end surface opposite the chamfer projection to form an inverted taper on the tooth form which prevents disengagement of the clutch.
