Based On The Component Die Cad / Cam Systems Development And Research

With the high development of computer and Web technology, mould manufacturing gives higher requirement. In order to meet the need of modern manufacturing, the CAD/CAM system of mould should have the following characters: shorter development time, stronger stability, higher agility, convenient for maintenance and upgrade and so on. So, the old CAD/CAM system of punching die can not satisfy the need of development. Now, the method of CBSD (Component-Based Software Development) is the hot topic for software development, and is applied in mould CAD/CAM system field gradually. According to CAD/CAM technology of punching die at present, this paper combine component and web technology to research the total design, key technologies, and realization for CAD/CAM system of punching die. The main research connects are as follows:Development base for Component-Based system. On the base of knowing component technology, the paper analyzes tree popular component technology: COM,CORBA and EJB, and chooses COM for system development. Through the principle Component-Based system, it gives component developing method.The whole design for Component-Based CAD/CAM system of punching die. Based on component technology and characteristics of network CAD/CAM, it analyses function requirements, takes the system function modules ; researches architecture of COM Component-Based and B/S,module application frame of COM Component-Based. Discuss in detail the system implementation program. According to component design idea, the system id divided into five modules: mould design, NC code creation, user authentication, management function, and assistant function, and describes them.Key technologies for Component-based CAD/CAM system of Punching die. The paper proposes a method of building the system's assembly drawing based on the knowledge tree. It researches database technology. And it uses COM and ASP to realize web interface's design.Realization of Component-based CAD/CAM system of Punching die. According to the process of CBSD, combining with principles of component hierarchy partition, it puts forward component hierarchy. And it realizes the following components: graph dealing, part drawing-created, NC code-created, and so on.
