中文摘要：

基于螺旋锥齿轮HFF加工方法，建立了螺旋锥齿轮的仿真加工模型，通过编制仿真加工程序，获取了螺旋锥齿轮齿面离散点，在此基础上实现了螺旋锥齿轮齿面的NURBS表示，并通过实例验证了该方法的可行性。

英文摘要：

Based on the HFT machining technique of spiral bevel gear, a simulation model was established and a series of discrete points were obtained through compiling emulator. According to the method, a mathematical model of the tooth surface was established by non -uniform rational B -spline （NURBS）, which was validated by an example.
