In order to manufacture the Klingelnberg cyclo-palloid bevel gear on domestic CNC spiral bevel gear cutting machine,the processing method with monolithic cutter disc is researched. Based on the cutting principle of cyclo-palloid bevel gear,the processing method which the gear is machined by spread blade method and the pinion is machined by single side method is proposed. According to the structure parameters of two-part cutters,the method for designing cutter-head and cutter blade of monolithic cutter disc is proposed.According to the curvature relationship between the meshed tooth flanks,a method for determining the amount of modification of cutter radius is established by iteration algorithm. According to the cutting principle and gear meshing theory,the formula for calculating the machine setting parameters and cutter parameters are derived.The processing experiment is completed on domestic CNC spiral bevel gear cutting machine with monolithic cutter disc. The correctness and feasibility of the cutting principle is verified by the rolling test of the experimental work piece.
