摘　　要：针对工艺尺寸链求解时遇到的难以理解和容易出错的问题,全面分析了3种典型工艺尺寸链的解算方法,对封闭环的确定、尺寸链的创建、"假废品"的处理以及公共环的求解提出了有效的措施和方法。Based on the questions difficult to understand or easy to make mistakes when calculating the technologic dimension chains, the author makes overall analysis on calculating ways of three typical technologic dimension chains. It puts forward effective measures and ways to the confirmation of close - loops, creation of dimension chains,treatment of ＂false scraps＂ and solving of public loops.
