A method of face gear grinding by involute disc wheel was proposed for precision machining.Tooth surface equation of face gear with disc wheel grinding was derived in accordance with the surface forming process and grinding principles.A special CNC（computerized numerical controlled）machine was developed for face gear grinding,and the method was given for face gear grinding based on the structure of the machine,the tool path generation of meshing points was also calculated.Grinding process of face gear was simulated by VERICUT.Finally,the processing experiments of grinding were conducted,and the coordinate values of tooth surface points were detected,by which the maximum deviation of-10.1-12.1μm was obtained.The results verify that the processing method of face gear grinding with involute disc wheel is correct.
