中文摘要：为快速辨识五轴机床旋转轴位置无关几何误差(PIGEs),提高旋转轴几何误差辨识精度,提出了一种采用三种球杆仪安装模式的旋转轴PIGEs简便辨识方法。在三种球杆仪安装模式下,通过齐次坐标变换建立了包含安装误差与旋转轴PIGEs的杆长变化模型。利用仿真分析了PIGEs对三种安装模式下球杆仪轨迹的影响,结果表明三种安装模式下控制单轴运动可以实现8项PIGEs的辨识。在辨识实验中,通过对球杆仪安装误差的测量来消除其对辨识精度的影响,以实现旋转轴8项PIGEs的辨识。最后对旋转轴8项PIGEs进行了补偿,实验结果表明,补偿后的误差最大绝对值由103.9μm减小至0.46μm,验证了所提辨识方法的有效性和准确性。

外文摘要：In order to quickly identify PIGEs of rotary axis of five-axis machine tools,and improve the accuracy in identifying geometric errors of rotary axis,a simple identification method was proposed for PIGEs of rotary axis using three installation modes of DBB.The mathematical model of bar length changes included installation errors and PIGEs of rotary axis was established based on homogeneous coordinate transformation under three installation modes of DBB.The effects of PIGEs on the paths of DBB were analyzed by simulation under three installation modes,and the results show that eight PIGEs may be identified by controlling uniaxial motion under three installation modes.In the identification experiments,the influences of identification accuracy were eliminated by measuring the installation errors of DBB,and the identification of eight PIGEs of rotary axis was realized.Finally,eight PIGEs of rotary axis were compensated,and the experimental results show that the maximum absolute value of the compensated errors is reduced from 103.9 um to 0.46 um,which verifies the effectiveness and accuracy of the proposed identification method.
