Abstract

Computer Aided Tolerancing (CAT) is the key technology of CAD and CAM integration. However, nowadays the tolerance analysis and synthesis in CAD/CAM are mostly realized by manual methods or the experience of the designers. Thus this not only increased the workload of the designers but also wasted a lot of time. As a result, this paper applies dimensional chain technology in AutoCAD2010 software through ObjectARX development tool to realize the automatic dimensioning and tolerancing. In the process of software secondary development, the deep first search method is adopted to generate dimensional chain automatically, and worst-case method and minimum cost method are separately applied to carry out tolerance analysis and synthesis. Finally an example is presented to validate the given method.
