A predesigned symmetrical parabolic function of transmission errors with given amplitude was obtained by optimization of modification parameters for the grinding wheel tooth profile, and a desired modification mode in longitudinal direction was obtained by controlling computer numerical control (CNC) multi-axis motions. The results show that this method enables designers to design the tooth surface of the face gear according to performance requirements, and to finish processing of face gears on a CNC grinding machine. The function-oriented design method can make the transmission errors and tooth contact paths satisfy
