Abstract
This paper presents the computerized generation and surface deviation correction of face gears generated by skiving. Firstly, the mounting relation among the skiving cutter, the virtual shaper, and the being-generated face gear is defined and the velocity relation analyzed. Secondly, the equations for the rake face angle and back flanks of the skiving cutter are defined, and the profile of the cutting blade obtained. Based on the kinematics of the generation movement of the skiving cutter, the surfaces of the face gear teeth are derived. The influence of the parameters of the cutter profile on the face gear surface topology is studied. Thirdly, the correction of the face gear tooth surface deviation has been achieved to some extent by adjusting the cutting depth, the rotation angle of the face gear, and the cutter offset distance during the process of machining. Finally, the simulation of the proposed machining process has been verified with VERICUT. The results show that the deviation of the face gear tooth surface is consistent with that obtained by the computerized generation as proposed in this paper.
