Design Knowledge and Process Management Method Based on 3D CAD System

With the diversification of customer needs and the widely use of 3D CAD systems, in order to make the 3D CAD system truly become the best carrier of professional technologies and realize the accumulation and reuse of enterprise design knowledge and design process, a design knowledge management method based on 3D CAD system is presented. In this method, a Design Navigation system based on 3D CAD system is researched, which can build Design Navigations for different products with language engineers are familiar with, and make product design visualized and processed. The mechanism of knowledge classification, management and reuse is also established for Design Navigation, design model, standards manual, formula, charts, drawings, and so on. This method was applied in piston design, and was approved to be effective in design knowledge accumulation. With this method, design experiences of senior staff can be accumulated within the enterprise in forms of parameterized features, standardized design process, precise rules and verified methods. Finally, design efficiency and quality of modularized and serialized products were improved, and the accumulation of design knowledge and design process was strengthened.
