| Abstract: | Expert knowledge taxonomics and repre sentat ion” in process planning is one of key technologies in developing generativ e CAPP system. This paper discussed some important issues such as knowledge taxo nomies and representation from the viewpoing of mechanical machining process. Th e result of knowledge taxonomies according to the hierarchy of machining process was presented in the paper, and all kinds of knowledge were represented with Ob ject Oriented concept and frame representation on the basis of the taxonomies. This kind of representation improved the maintainability of the knowledge base. |
