Abstract
A process of forming the longitudinally curved teeth of bevel and hypoid gears is disclosed. A dish-shaped tool is oscillated relative to a work gear with the oscillating causing the dish-shaped tool to swing through an arc corresponding to the longitudinally curved teeth of the work gear. The inventive process comprises additional motions included in a timed relationship with the oscillating motion of the dish-shaped tool. The included motions are functions of the phase angle of the oscillating dish-shaped tool 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 cutting or grinding processes utilizing, respectively, dish-shaped cutting tools or dish-shaped grinding wheels.
