A process of forming the longitudinally curved teeth of bevel and hypoid gears is disclosed. A dish-shaped tool (2) is oscil- lated relative to a work gear (12) with the oscillating causing the dish-shaped tool (2) to swing through an arc (7) corresponding to the longitudinally curved teeth of the work gear (12). The inventive process comprises additional motions included in a timed re- lationship with the oscillating motion of the dish-shaped tool (2). The included motions are functions of the phase angle of the oscillating dish-shaped tool (2) and the timed relationships are defined by a power series. The process enables improved control of contact patterns of mating gear teeth. The process may be computer numerically controlled. The process is applicable to cut- ting or grinding processes utilizing, respectively, dish-shaped cutting tools or dish-shaped grinding wheels.
