摘　　要：在工艺方案决策过程中,为了更好地对工艺路线进行表达和优化,使用工艺尺寸路径图来描述工艺过程中各基准、加工顺序和全部尺寸关系,这样有利于对工艺方案进行决策,最终获得最佳工艺方案。使用工艺尺寸路径图,可以使工艺方案确定的过程变得简单、明确;再配合工艺尺寸式可以计算出相应的工序尺寸及其公差,可以更好地满足计算机辅助公差设计及参数化设计的需求。In the decision making process scheme, in order to express and optimization of process route better, use the process dimension route map to describe each process datum, processing order and all dimensions, so as to facilitate the decision making on technology, obtain the best process scheme. The use of process dimension path graph, process can make the process scheme for the simple, clear; coupled with process dimensional formula can calculate the working dimensions and tolerances of the corresponding, can better meet the needs of computer aided tolerance design and parametric design requirements.
