【摘要】 鉴于机械制造中测量结构尺寸误差比较困难，提出了确定结构误差值的计算方法．让结构参数从初始的理想无误差状态一轮一轮地修正，直到使修正后的结构参数达到用它所求的主轴端位置同测量的主轴端位置基本吻合，即可认为各项误差已修正完毕．在计算当中，首次提出用位置反解来求解的方法，突破了求正解时需要解非线性方程组的传统思路，考虑到机构运动过程中的连续性和可实现性，所求正解是机构运动过程中的惟一解更多还原

【Abstract】 Assessment of errors made by machine in manufacturing is difficult to quantify. The detection and correction process should be calibrated with reference to an error free machine. Those parameters that control the process should be analyzed step by step until each position is corrected. The positional solution is the only solution that satisfied continuity and could be realized during the motion of the mechanical parts.更多还原
