摘　　要：研究6-TPS型并联坐标测量机误差建模,并分析各误差因素对工件测量误差的影响度。运用一种构件、副误差矩阵的误差描述方法确定了影响并联坐标测量机工件测量误差的各项误差因素,然后建立了测量误差模型,并通过仿真的方法详细分析了各误差因素对工件测量误差的影响度,为6-TPS型并联坐标测量机的精度设计、补偿奠定了基础,也将为测量机的运动校正和控制提供参考。Workpiece probe error modeling on 6-TPS parallel mechanism Coordinate Measuring Machine was researched, and every error ingredient influence degree to workpiece probe error was analyzed.
