摘　　要：基于保持加工过程中刀具与工件之间的相对运动和相对位置不变的原则,论述用Free—form型数控磨齿机等效替代刀倾型摇台磨齿机展成螺旋锥齿轮的方法。通过分析加工参考点处刀具与轮坯相对运动的高阶加速度,推导了显式表达的两类机床加工参数的转换公式。通过对一个实例的计算及两类机床所展成齿面的接触分析结果的比较,证明所提出的计算公式精确高效,能满足数控机床实时控制的要求。Based on keeping the relative position between the cutter and work piece unchanged, the problem how to substitute Free-form CNC grinding machine for cutter-tilt cradle machine tools to generate bevel and hypoid gears was studied. The transformation formulas of the machining setting parameters from grinding machines to Free-form grinding machine in explicit form were derived by means of analyzing the higher order spatial acceleration at the reference point, An example was given to verify the algorithm, and from the TCA results it is proved that the transformation based on the reference point is accurate and efficient enough to meet the requirements of real-time interpolation of the CNC system.
