利用雷尼绍XL-30激光干涉仪对MVC850B型数控铣床的定位精度进行精密检测,通过分析测量结果,计算该数控铣床的反向间隙和螺距误差,并给出相应的误差补偿值。然后对反向间隙和螺距误差进行误差补偿,利用Matlab软件对相关实验数据进行分析。实验表明,通过该方法进行误差补偿将大大提高数控铣床的定位精度。最后对补偿前后的数控铣床进行工件加工验证实验,结果表明,文中提出的误差补偿方法,将有效提高零件的加工精度。

The positioning accuracy of MVC850B NC milling machine is accurately detected by Renishaw XL-30 laser interferometer.By analyzing the measurement results,the backlash and pitch error of the NC milling machine are calculated,and the corresponding error compensation value is obtained.Then the error of backlash and pitch error is compensated,and the relevant experimental data is analyzed by Matlab software.Experiments show that the error compensation by this method will greatly improve the positioning accuracy of the NC milling machine.Finally,the workpiece machining verification experiment is ca...
