Patent ID: 8282322

Claim:
A method of finishing race grooves and lobe outer surfaces of a constant-velocity race gear centered on a gear axis, the method comprising, the steps of sequentially: a) engaging a first groove of the race gear with a rotating groove-machining tool and relatively moving the race gear and rotating groove-machining tool arcuately to finish the first groove while holding the race gear against rotation about its gear axis; b) disengaging the first groove of the race gear from the rotating groove-machining tool while holding the race gear against rotation about its gear axis; c) rotating the race gear about its gear axis to align a second groove with the rotating groove-machining tool while engaging a first lobe outer surface with a rotating surface-machining tool to finish same; and d) repeating steps a) through c) to finish the second groove and a second lobe outer surface and so on until all the grooves and lobe outer surfaces of the race gear are finished.
