摘　　要：为了提高成形磨齿机对中精度和合理分配齿面对中余量,提出了一种优化的成形磨齿机自动对中及余量分配计算方法。建立自动对中测量及余量计算模型,包括基于广义极坐标法的测头在线测量模型和渐开线齿形的余量计算模型,在此基础上,提出一种基于拓扑采点的自动对中策略,通过多次寻优求解得到最优的对中值和磨削余量。实验结果表明,采用该方法计算得到的对中值和余量满足成形磨齿加工要求,齿面磨削余量分配更加合理,提高了磨齿加工效率,消除了齿面磨削烧伤的风险。In order to improve the tools centering accuracy of computer numerical control（ CNC） gear grinding machine and make the distribution of tooth flank allowance more reasonable,an optimized method was proposed to calculate the tools automatic centering and allowance distribution of CNC gear grinding machine.The model of tools automatic centering and allowance distribution was established based on the generalized polar coordinate. Then,based on point set topology an automatic centering strategy was proposed to obtain the optimal centering parameters and tooth flank allowance. Experimental results showed that the proposed method met the processing requirement of CNC gear grinding and the distribution of tooth flank allowance was more reasonable. The method could improve CNC gear grinding productivity and reduce the risk of tooth flank grinding burn.
