【 摘 要 】

With the train axle product as the research object, based on analysis of the functional needs of the CAD/CAPP parametric design system of train axle, the overall functional framework of the system is decided, and the Unified Modeling Language (UML) activity diagram of the system is designed. The parametric design methods of the system are discussed, including the shaft shape features and parametric programming, the establishment of feature drawing function. Based on Visual Basic 6.0 programming language and SQL Sever database technology, the CAD/CAPP parametric design system of train axle is developed, and an application example is given. The application result shows that the system is easy to operate and significantly saves the design time of the product. The format of its generated drawings is unified, and accords with the national standard specification.
