Abstract
To accelerate face-gear engineering application, a precision grinding method for complex surface of aero face-gear is provided in this paper. Based on the principle of face-gear drive, the principle of face-gear grinding by disc wheel is analyzed, and the tooth surface equation of the face-gear is calculated with coordinate transformations. Taking the grinding needs into account, a special machine tool is developed, and movements control method of face-gear grinding by the disc wheel on the machine tool is proposed. To ensure the correct tooth profile of the disc wheel, the method of wheel dressing is provided and the optimum design methods of CNC cutter sites and step sizes selection are provided. To verify the feasibility of the grinding method for face-gear, the simulation of face-gear grinding by disc wheel is performed based on VERICUT software according to the grinding method. The experiments of face-gear grinding and the wheel dressing are carried out finally, and the results show that it is feasible for face-gear grinding using the involute disc wheel and the special machine tool.
