首先分析了目前常用的机床几何误差测试方法的缺点。在此基础上,研究了一种几何误差测试及误差分离方法。建立了铣削加工中心的测试空间,给出了9项定位误差测试的方法。建立了机床误差元素的分离模型,各轴的角度误差通过该轴的两项定位误差数据得到,直线度误差通过颠摆和偏摆误差计算得到。在某铣削加工中心上进行了定位误差测试,通过误差元素的分离模型得到了15项误差元素。该误差测试及分离方法实现了机床几何误差的快速测试。
First of all, it analyzes the shortcomings of the commonly used method of machine tool geometric error testing. On this basis, we study a geometric error test and error separation method. The test space of the milling center is established, and nine methods of positioning error test are given. The separation model of the machine error element is established. The angular error of each axis is obtained by two positioning error data of the axis. The straightness error is calculated by the error of the top and the yaw. In a milling machining center positioning error test carried out by the error element separation model obtained 15 error elements. This error test and separation method enables rapid testing of machine geometry errors.
