The Research Of Instance Reasoning Comprised Hybrid Integrated CAPP System's Key Technique And Application

This paper use national 863-CIMS application demonstrate project (contract code: 863-500-910-1032) as instance, use hybrid integrated CF-CAPP system as study case, present the exploitation thought of "instance reasoning comprised hybrid integrated CAPP system", practice prove: the study of integrated CAPP system that use PDM as platform, technique data as center, comprise multiple technique decide method or process-design management has important theory value and realism meaning.The main content and achievements of research list as fellow:① After introduce the basic components of CIMS, we discussed the roles and status of CAPP system in the AMT modes. Aimed at the basic concept, working mode, the study situation in the outside and domestic and the application problem in theory discuss and practice working the paper go deep into analyze, point out the development tendency of CAPP system.② Bring forward the core idea of hybrid integrated CAPP system,established the systematic structure of hybrid integrated CAPP system which comprised of instance reasoning technique and multiple process decision-making mode and macro process management .③ Established basic object-class system of hybrid integrated CAPP system, adopted the mode which combined feature and object, established information model of feature-based object oriented production; At the same time, researched the object-class level structure of wide meaning of manufacture resource and object-oriented express of process knowledge and the data model of process rules instance .④ Established the process decision-making model of hybrid integrated CAPP system, presented a method based on instance reasoning that can divide CAPP instance into "part level -grouping template level -instance level" the three level of grouping index scheme and the detail arithmetic of comparability coefficient, discussed the scheme of instance knowledge acquiring and instance correcting; In the process of knowledge-based creative reasoning, detailed studied the knowledge-based successively-step reasoning control strategies, further more put forward the management model that under the way of classification programming method to construct the database and knowledgebase of process design in grade model.⑤ Researched process task based macro-process management subsystem. Afterstudied the process design course, present the process design management method that division the management structure of archive and course, organize the archive in terms of production structure tree, organize course by mission flow. Then present application instance.⑥ This paper use national 863-CIMS application demonstrate project (contract code: 863-500-910-1032) as instance, under ground of introduce the TIS subsystems' elaborate design that author participate and then bring out the application instance. The implement of the system in the factory acquired satisfied effect...
