摘　　要：作为机械产品设计和制造过程中的一项重要内容,计算机辅助公差设计(CAT)是CAD/CAPP/CAM集成的关键技术,是国内外先进制造技术发展中亟需解决的问题。计算机辅助公差设计覆盖面非常广泛,涵盖公差规范和标准化、设计/制造工艺/产品生命周期管理中的公差设计、检测与测量以及功能公差设计。本文首先简要分析这些热点问题的研究进展情况,其次介绍本专辑收集的第13届国际生产工程科学院计算机辅助公差设计会议中的最新研究成果,分析该领域的最新研究进展,希望能帮助读者了解相关研究工作并促进研究人员开展讨论,进一步实现计算机辅助公差设计中的关键技术的突破,促进CAD/CAPP/CAM的集成。Computer aided tolerancing （CAT） covers a wide range of subjects including specification and standardization, tolerancing in design/manufacturing process/product life management, verification and metrology, and functional tolerancing. Dimensioning and tolerancing standards origi- nated about 77 years ago in the form of various na- tional and company standards that governed engi- neering drafting and documentation practices, These standards have evolved and their rapid development has brought about many significant changes to tol- erancing in design and manufacturing. The release of ISO 14405-1：2010 （ISO, 2010） has introduced a rich new set of size specification modifiers, which in- cludes two-point and spherical local sizes least squares, maximum inscribed and minimum circum- scribed associations, and calculated diameters. Morse et al. （2012） present ＂size＂ as a fundamental engi- neering notion from several viewpoints, trace its evolution in engineering drawings, and discuss the implications of the use of size modifiers.
