Abstract
A method is disclosed wherein standard generating motions for the production of bevel and hypoid gears are modified by the substantially simultaneous inclusion of additional controlled motions which enable a desired tooth surface geometry to be produced on the gears. The additional motions comprise varying the position of intersection of the theoretical generating gear axis and the pitch plane and/or varying the orientation of the tooth surfaces of the theoretical generating gear with respect to the body of the theoretical generating gear. A CNC machine is preferably utilized for carrying out the inventive process. The inventive process is applicable to generating processes of both the face milling and face hobbing type.
