A method of logarithmic spiral bevel gear NC automatic programming based on Pro/E NC module was introduced. An accurate 3D model was created in Pro/E. In the CAM module of Pro/E NC, by setting the manufacturing parameters, processing data and program, tool path was generated, simulation processing was made. Then NC program was generated by using the Pro/E NC post processing function. The finished product was processed by using the Dejima five axis CNC machining center.It provides reference for design and manufacture of complex gear or curved surface.
