[Abstract]:The modern fierce market competition puts forward higher requirements for the rapid response ability of enterprises. The integration of design and manufacturing efficient three-dimensional design environment is one of the key technologies to solve this problem. In this paper, the problems of product information integration, design and manufacturing collaboration and other design and manufacturing integration under the full three dimensional platform are studied systematically. The main research contents and achievements are as follows: 1 according to the requirements of design and manufacturing integration, the main contents of design and manufacturing integration are given, the framework model of design and manufacturing integration in full three-dimensional environment is established, and the key technologies under this framework are put forward. (2) the design and manufacturing information integration based on PDM and its shortcomings are analyzed. By using the idea of MBD for reference, the product information integration based on 3D model is put forward, and the process information extension of 3D model is realized by introducing XML technology. (3) the overall framework of design-manufacturing collaboration based on process-driven is established, the organization mode of design-manufacturing collaboration is expounded, the information model in collaborative process is established based on IDEF1X method, and the collaborative method based on PDM and free process is put forward to realize the cooperation of design and manufacture. Based on Pro/Engineer platform, the architecture and function model of the design and manufacture integration system are designed, the key technology of software implementation is given, and the prototype software of design and manufacture integration is developed. finally, some functional interfaces and applications of the software are shown.
