Abstract

See full text

For machining a concave-convex gear in which concave teeth of the concave-convex gear and convex teeth of a mating gear are formed in a circumferential direction, to allow torque transmission to or from the mating gear, in a trajectory extracting step a relative movement trajectory of each convex tooth of the mating gear with respect to the concave-convex gear at the time when torque is transmitted is first extracted as a machining target. Then, in a machining step, the concave teeth of the concave-convex gear are machined on a disc-shaped workpiece by moving at least one of the disc-shaped workpiece and a working tool such that a relative movement trajectory of the working tool with respect to the disc-shaped workpiece coincides with the relative movement trajectory of each convex tooth of the mating gear with respect to the concave-convex gear extracted in the trajectory extracting step.
