The common conjugate surface includes tooth surface of gear, working surface of solid CAM, helicoidal surfaces existing in spiral burr, worm, chip flute of cutters, and so on.
A mathematical model of spiral bevel geartooth surface was built by analyzing manufacture method and meshing theory.
通过分析锥齿轮的加工方法和齿轮啮合理论，建立了螺旋锥齿轮齿面数学模型。
