摘要：
A machining method based on four-axis computer numerical control machine tool and multi-line envelope grinding face gear with grinding disk was proposed to manufacture the hardened face gear with high precision, increase the versatility of tools and simplify the structure of machine tools. The grinding disk with a circular arc on the top edge was designed to profile the tooth surface of the shaper. The mathematical model of face gear grinded by the grinding disk was established and the tool path of the grinding disk was planned. The influences of cutting edge arc radius and torque angle on tooth envelope residual were investigated by numerical simulation. Combining with the selected structure of four-axis computer numerical control machine tool, the computer numerical control motion rule of the grinding disk manufacturing face gear was derived and the machining simulation was performed in VERICUT. The simulation model was compared with the theoretical tooth surface, the maximum value of tooth surface deviation was -4.3-4.7μm, and the result can confirm the correctness of the proposed machining method and prove that the appropriate cutter parameters adopted according to the influence law of tooth envelope residual can ensure the accuracy of tooth surface and improve the machining efficiency. © 2021, Editorial Department of Journal of Aerospace Power.
