摘要
在漂移模型、虚拟边界要求、条件公差理论以及ISO 和国家标准的公差原则基础上,给出可用于孔轴类零件公差一致性验证的软件量规数学等效式。为基于约束的参数化CAD系统中,计算机辅助公差设计的评价提供了理论依据,对促进CAD/CAM 集成。
Based on floating model,virtual boundary requirements(VBRs),conditional tolerances(CTs) and rules of ISO and China standards,this paper presents some mathematically equivalent formulas used to design the soft gauge.It provides theoretical basis for evaluation of computer aided tolerance design in parametric CAD system based on constraint and facilitates the integration of CAD/CAM,which has significant values in science and practice.
