ABSTRACT

In recent industry, Computer-Aided Design is the most important tool of product development, especially assists designers to draw computer graphic of component. But a tool such as this is just Computer-Aided Drawing, for achieving the concept of Computer- Aided Design, the system has to get not only drawing but the other ability to aid designer making decision. Target of this study is to establish a Knowledge-Based Design System. First, decompose the informations of product by design process, and make them as objects with OOT and save objects in library, keep the saved information can be reuse. Then modulify objects to reduce the complexity of assembling. At the last, establish a system to drive such objects and assembly automation in CAD Application with Virtual Prototyping Technology, to get a complete assembly of product.

Keywords : Knowledge-Based Design, Modulify Technology, Assembly Automation, Virtual Prototyping Technology Table of Contents
