geometric dimensional tolerance

The general framework and prototype system for synthetic design of dimensional and geometric tolerance based on three- dimensional CAD system are established.

给出了基于三维CAD系统的计算机辅助尺寸公差和形位公差综合设计的总体框架和原型系统。

Three examples are studied to demonstrate that the system can effectively design dimensional tolerance and geometric tolerance, and integrate tolerance design and tolerance evaluation.

三个实例分析验证了此系统可有效地实现尺寸公差和形位公差的综合设计，同时完成了公差评价系统和公差优化设计系统的有机集成。

A composite tolerance design method is proposed for dimensional tolerances and geometric tolerances.

提出尺寸公差与形位公差的混合设计方法。
