摘要
本文研究了三轴直角坐标系设备的垂直度误差补偿方法。针对移动平台提出了多轴垂直度误差的数学模型,并通过关节臂坐标测量机获取六自由度误差运动参数。根据这些参数,分析了多轴垂直度误差的补偿策略,并构建了整机误差运动模型。实验结果表明,该补偿方法有效提高了数控雕刻机的定位精度和多轴垂直度精度,垂直度误差从89.984°降低至89.3598°。本研究为直角坐标系运动平台的精度补偿提供了理论依据和实践指导。
This paper studies a compensation method for the verticality error of three-axis Cartesian coordinate system equipment based on the geometry model of a straight surface.A mathematical model for multi-axis verticality errors is proposed,and six-degree-of-freedom motion error parameters are obtained using a robotic arm coordinate measuring machine.Based on these parameters,a compensation strategy for multi-axis verticality errors is analyzed,and a whole-machine error motion model is established.Experimental results show that this compensation method effectively improves the positioning accuracy and multi-axis verticality accuracy of the CNC engraving machine,reducing the verticality error from 89.984°to 89.3598°.This research provides theoretical support and practical guidance for accuracy compensation in Cartesian coordinate system motion platforms.
