The Rotary Part Is The Design And Realization Of Intelligent Capp System

Process planning is the bridge which link product design with manufacture. CAPP as Computer realizing way for process planning, is the critical technology to realize CIMS and CAD/CAM integration. However its application study and development relatively lag CAD and CAM. The reason lies in two facets: the one is that process planning is not supported by better theory and firm scientific foundation, the other is that CAPP system's depending on works environment limits itself application and development. Considered from its own development as well as integration with other skills, CAPP must possess the capacity of fitting various situation. To adapt to the trend, referring to the idea of experts system that knowledge is separated from deduce procedure, a generative CAPP prototypes system for turning parts was studied and designed, which included the creation of system structure. Description and input of parts process database, and process deduce and illation etc.On a basis of analyzing turning parts' composing characteristic, adopting the form describes, the form factor's definition & coding for parts was realized, the information model of parts was formed, and the inputting design of parts information was accomplished. Foundation of analyzing the inner relation between processing design and knowledge needed, using relation list, process knowledge data's expression & saving was realized. Still in term of process knowledge structure and designing goal, taking advantage effacing illation, classification, the procedure design of process decision was achieved. In system not only the process knowledge & decision procedure apart can suit for updating & protecting of process knowledge in different environment, but also the inputting module of parts information & process database can be used in other similar system.The system uses Visual Basic 6.0, and runs in Chinese Windows, which makes it has a reasonable structure & perfect interface, also makes it easy to amplify & protect. The running consequence can ultimately realize our designing target.
