摘　　要：在机测量可在加工过程中实时测量,有效提高面齿轮的加工质量及测量效率。考虑面齿轮在机测量预行程误差对齿面精度的影响和齿面匹配精度低的问题,制定了基于蜗杆砂轮磨齿机的在机测量策略,将多种误差影响因素作为输入,测头综合预行程误差作为输出,构建基于PSO-CNN神经网络的综合预行程误差预测模型完成误差补偿。提出齿面精匹配方法,构建六参数优化模型使测量齿面与理论齿面进行匹配得到齿面误差。最后,测量实验结果显示,左齿面精度提高61.33%,右齿面精度提高71.15%,在机测量与克林贝格测量仪测量结果基本一致,满足面齿轮在机测量精度要求。On-machine measurement can be used for real-time measurement during machining,which can effectively improve the machining quality and measurement efficiency of face gear.Considering the influence of the pre-travel error of face gear on-machine measurement on the tooth surface accuracy and the low tooth surface matching accuracy,an on-machine measurement strategy based on worm grinding wheel gear grinding machine,which takes various error influencing factors as input and the comprehensive pre-travel error of probe as output.A comprehensive pre-travel error prediction model based on PSO-CNN neural network is formulated to complete error compensation.A precise tooth surface matching method is proposed,and a six-parameter optimization model is established to match the measured tooth surface with the theoretical tooth surface to obtain the tooth surface error.Finally,the experimental results show that the accuracy of the left tooth surface is improved by 61.33%,and the accuracy of the right tooth surface is improved by 71.15%.The results of on-machine measurement are basically consistent with those of Klingeln Berg measuring instrument,which meet the requirements of on-machine measurement accuracy of face gear.
