摘要
介绍直接工程的概念。给出直接工程环境下变异设计的抽象描述 ,并分析其特点。对变异设计中的相似性类型进行研究 ,提出基于总体层和特征层相似性比较的变异工艺设计方法 ,给出有关相似元的比较算法。该方法已用于指导实用型
The concept of Direct Engineering (DE) is introduced in this paper. An abstract description of variant design under DE is given and the characteristics of variant design are analyzed. After the study of similarity categories of variant design is made, a variant process design method which is based on the similarity comparison on general and geometric feature levels is proposed. The comparison algorithms for some similar units are given as well. The method introduced by this paper has been used to conduct the development of practical CAPP system.
