摘　　要：A/C轴双摆角铣头的定位精度与重复定位精度是影响数控铣床加工精度的重要因素。对铣头的定位误差进行了详细分析;介绍了利用激光干涉仪对其定位误差与重复定位误差进行测量的方法,设计了其主要部件A轴与C轴的定位误差与重复定位误差的检测方案。通过测量得到有关实验数据,对实验数据进行整理分析,得出实际定位误差与重复定位误差,与预先的精度设计指标相比较,满足实际加工精度要求和设计要求。The positioning accuracy and repeated positioning accuracy of A/C axes bi-Rotary milling head effect di-rectly its working accuracy. The positioning error is analyzed in details. The method to measure the positioning error and the repeat positioning error is introduced with the laser interferometer, which designs the testing steps of the main compo-nents of A and C axes. Through measuring the relevant experimental data are got, interpreted and analyzed to get the actual position error and repeated positioning error. Comparing with the advance design indicators, it can meet the working accu-racy and design indicator.
