In order to improve processing surface quality and efficiency of the conical cycloidal gear,the techniques of face milling conical cycloidal gears were presented.The mathematical model of the effective cutting ellipse of the face mill was established.The front inclination angle and tilt angle were employed to solve the problems of local interference and global interference respectively.The geometrical model and five-axis numerical control(NC)simulation model of face-milling conical cycloid gear were then established accordingly,and the optimal tool path was obtained.NC simulation shows that the parameters are set reasonably,the machining track is even and smooth,and there is no interference.Finally,the face milling cutter was used to realize the machining of the precision conical cycloidal gear on the five axis computer numerical control(CNC)milling machine tool,which has verified the feasibility and effectiveness of the machining method of milling conical cycloidal gear with face mill.
