摘　　要：通过改进重构凸轮X-C轴联动加工模型,建立X-C轴联动加工通用补偿模型;采用最小二乘拟合还原数据曲线并得到规则化输出,结合延迟补偿模式,实现凸轮加工的在线检测补偿功能。由此可解决直线和转角反馈无法补偿X-C轴联动同步误差的问题,有效降低X-C轴联动加工过程中同步误差带来的影响,提高了凸轮的加工精度和质量,为凸轮加工在线检测补偿提供可行方案。Through the improvement and reconstruction of cam X-C axis linkage machining model,the general compensation mod⁃el of X-C axis linkage machining was established;by using the least square fitting to restore the data curve and get the regular output,and combined with the delay compensation mode,the online detection and compensation function of cam machining was realized.Therefore,it can solve the problem that the linear displacement and angular feedback cannot compensate synchronous error of the X-C axis linkage,so the influence of the X-C axis linkage synchronous error can be effectively reduced,the machining precision and quality of cam can be effectively improved,which provides a feasible scheme for the online detection compensation of cam machining.
