摘要
建立工艺尺寸链的基本公式、计算方法和步骤以及在工艺规程设计中的应用。指出了计算尺寸的关键问题在于正确地确定封闭环。而确定封闭环的关键,除了紧紧抓住封闭环尺寸“间接获得”这一要领,还要考虑零件的具体加工方案。
The paper introduces establishing basical fomula, calculational methods, steps and application in technology rules design of technology dimensional chain. it indicates that calculational key lies in correct ascertaining of close loop. Grasping tightly the indirect obtained dimensional and considering still work pieces specific machining scheme are key of close chain's ascertaining
