The digital models of Cycloid Bevel Gears and hypoid gears used in general NC machining are obtained by establishing analytical formulas and accurately solving the discrete points of the tooth surface based on the principle of spirac gear cutting and real tooth surface forming. Based on this model, the gear pair obtained by general NC machining has the same contact strength, tooth surface shape, feeding characteristics, etc. as the gear pair obtained by special machine tool, which ensures the feasibility of this machining technology, and reduces the complex calculation and repeated adjustment of the transformation from special machine tool to general machine tool.
