定位误差大小是判断定位方案能否保证加工精度，合理选择定位方案的重要依据，也是审核夹具精度的主要指标。分析计算定位误差是夹具设计中一个十分重要的环节，计算过程的关键是如何将基准不重合误差、基准位移误差两者合成为定位误差，基于多年教学和设计实践基础，研究形成了相对快捷的合成方法。

The size of positioning error is the important basis of judging whether the positioning plan can ensure machining accuracy and reasonably choosing positioning plan or not. It is also the main specification of inspecting fixture accuracy. Analyzing and calculating on positioning error is an important step for fixture designing. The key to the calculating process is how to make misalignment error with reference point and displacement error with reference point into the positioning error. Based on over years’ teaching and designing practice,the new and quicker method is suggested.
