摘要
结合实例分析定位误差计算中遇到的一些容易模糊和疑难问题:工件位置公差的处理、误差合成中正负符号的判断、组合表面定位误差计算分析,提出解决的思路和方法,并为合理的定位方案设计提供一些建议。
Abstract：Combination with examples, to analysis some vague and difficult questions such as dealing with position tolerance of workpiece ,judging ＂ ＋ , - ＂ in the synthesis of error and caeulating location error of portfolio surface in the calculation of location error, then put forward solving way and methods. At the same time, to provide some advice for reasonable location program design.
