Study the face gear machining method by using the plunge milling processing, according to the face gear slotting processing principle and gear engagement principle, a plunging processing method with multi group envelops processing is proposed. Based on the concept of virtual copying of plunge milling cutter to the gear shaper tool, the rotation relation between the gear shaper cutter tooth surface equation, contour surface e- quation and cutting tool and the face gear moving coordinate system are deduced, and the spur face - gear is processed through multi group envelops. The mathematical formula of the plug mill copying the of the profile of gear shaper cutter and the based on gear shaper cutter and the machine tool structure are given. According to numerical control manufacturing techniques, the NC code based on face gear machined equation is obtained. It is imported into VERICUT to simulate and process. Through the contrasting between simulation and theoretical tooth surface, the feasibility of the proposed method is proved. The proposed method is a new rough machining method for face gear numerical control plunge milling processing, it has great reference value for face gear manufacturing.
