The Research Of Computer Aided Automobile Panel Stamping Process Planning System

In this paper, facing the process planning and the actual manufacture, the methords of knowledge engineering have been applied to design the database, the database technology is adopted to the development of the basic structure of the database and it's management system. And the stamping process planning system has been developed.In this paper, By analyzing the types of process design knowledge, some key technologies such as the knowledge acquisition, classification, translation and representation have been studied well. On the basis above, several computer methods to deal with knowledge have been discussed.On the study of database design methords, in this paper, the knowledge-based database design technology is proposed, the requirement analysis, the concept model and the logical design have been solved, the structure design have been achieved also, according to the theory of database design. On the basis of above, the knowledge-based database has been established, which based on Visual FoxPro6.0 (VFP6.0) relational database, including the parts query system, the process query system, the experience query system and the resources query system.In this paper, the DBMS is developed by using the VFP6.0, which achieves the functions of addition, modification, deletion, inquiry and printing the knowledge files, etc. The KBMS can also realize the function of maintenance, which will make the validity, security and integrity of knowledge.In this paper, the knowledge-based stamping process planning system is developed by using the VC++ 6.0 , which applies knowledge to the anlysis of the process feature and the caculation of the main process parameter, then, aidsdetailed stamping process planning.
