摘　　要：为提高压机运行精度与稳定性,设计一种适用于倍福PLC的螺距误差补偿方法。依据激光干涉仪测量设备进给轴运行范围内不同点位的误差值,计算出对应位置的补偿值,通过相应算法实现对设备轴的定位进行补偿,从而提高进给控制精度。结果表明:该方法对设备轴螺距误差有显著改善,明显提升设备轴控制精度。In order to improve the running accuracy and stability of the compressor, a pitch error compensation method suitable for Beckhoff PLC is designed. The compensation value of the corresponding position is calculated according to the error value of different points in the operation range of the feed shaft of the laser interferometer measurement equipment,and the positioning compensation of the equipment shaft is realized through the corresponding algorithm, so that the feed control accuracy is improved. The results show that the method can significantly improve the pitch error of the equipment axis, and significantly enhance the control accuracy of the equipment axis.
