摘　　要：针对自主研发的切线法数控成形非球面机床，提出一种基于改进型PID控制算法结合开发型UMAC软件定位误差补偿方法，给出了具体实现步骤。通过建立改进型PID控制模型和开发型UMAC误差修正表对切线法数控成形非球面机床进行定位误差补偿，实际应用和实验验证表明，该方法可以有效地解决数控机床的定位误差问题。Based on feed-forward PID algorithm and UMAC software, a compensate location error methed is proposed for the aspheric CNC by tangent method which was developed by ourselves, and specific steps to implement this method is given. The experimental results of location error compensation showed this method can improve the location accuracy of CNC effectively by the established feed-forward PID model and an UMAC error correct table.
