Abstract:Traditionally, the manufacturing of face gear is depended on the simulation of the meshing between the face gear and the pinion, which leads to the cutter is not universal and the processing is complicated, aiming at this problem, by means of computer numerical control (CNC) technique, a method of application of planecutter in generating the face gear was proposed. Firstly, the design of the planecutter and the theory of the planecutter generating the face gear were elaborated, and combining with the technique in Gleason works, the required movements of machine tools were configured. Secondly, the mathematical model of the face gear tooth surface generated by the planecutter was derived, and the theory processing method was translated into CNC method by numerical deduction. Finally, the simulations of the theory and CNC method of the face gear generated by the plane cutter were performed. The result demonstrates that the face gear generated by the planecutter is highly precise as in theory, and the error of the tooth surface generated by CNC method is no more than 256 μm.
