摘要
本文介绍了从零件加工工艺过程角度出发，利用工艺尺寸链作综合分析和计算，合理地确定加工过程中各工序余量、工序尺寸及公差，为工艺设计提供了更加经济、合理的工艺参数，较好地解决了ＣＡＰＰ系统中有关尺寸链计算的问题．
In this paper a comprehensively analyzing and Calculating method of process dimensional chain is reported as viewed from process,allowance,dimension and tolerance of each operation are reasonably determined more economic and reasonable parameters are provided fortechnological design,and the problems about calculating the relative dimensional chains inCAPP systems are solved.
