摘要
在分析重型车床定位精度的激光测量原理和方法的基础上,采用激光干涉仪对X轴的定位精度和重复定位精度进行了测量,做出X轴的平均偏差特性曲线,获得其线性位移误差数学模型,利用最小二乘法得到X轴定位精度误差补偿模型,并进行了有效补偿。实例结果表明,本文方法有效且可行。
Based on the detailed analysis of the principle and way of laser measurement for position accuracy of CNC heavy-duty horizontal lathe,the laser interferometer is used to carry out the measurement of position accuracy and re-position accuracy in the X-axis direction so as to work out the average deviation characteristic curves in the X-axis and to obtain the mathematical model of its linear displacement errors.Also,the least square method is used to obtain the X-axis position accuracy error compensation model;and the effective compensation is made.The results from the real examples indicate that this method is effective and feasible.
