The Research And Development On Intelligent Stamping Die CAD System

In this paper the author's work on the intelligent stamping die CAD system is summarized, and the principles and implement of the system are expounded.First, in the paper, the general situation, the present problem and the developing trends in the future of stamping die CAD are introduced briefly, which provide sufficient theoretic basis for the development of the system. Second, the relative technique applied in the system is expounded from two sides. On one hand, the database structure design is explained in use of relational database and norm format theory, which is the primary management method of the data in the system. On the other hand, developing environment of the system is introduced, which is made up of graphic handling environment, software developing language and data transmission interface. In addition, the overall project design of this system is mainly dissertated in this part. Finally, the key functional modules of the system are expatiated in particular, which includes examining the logic rationality of the stamping part, analyzing the stamping process rationality, choosing the stamping process plan, designing the steps of the progressive die, designing the working parts and assembly drawing of the die and so on. In the above modules, fuzzy decision-making technique and expert system technique are adopted to solve the problem. In addition, some new algorithmic idea is put forward to improve the efficiency and quality of the system.
