The Management And Application Of Craft Data In CAPP

Computer Aided process planning-CAPP is a bridge which connects with CAD and CAM and is one of technical basis of most advanced manufacturing system. Serving as nucleus of information construction of enterprises, CAPP is very important for information construction of enterprise. It is basic foundation of enterprise producing activity that CAPP emerge craft resource data which are managed, if there are not supporting of CAPP ,managing system such as ERP can not fully accurately completely acquire resource data information which is necessary for making process through technical and craft department. More and more Enterprises have learned to know the importance of CAPP system. Selecting some suitable systems for themselves not only fully develops superiority, but also settles fine bases for information integrating of enterprise level and ERP's implementation.This paper puts forward craft resource design and constructing through the descriptions of feature, classification and organization of craft resource data, established craft resource model based O-O CAPP. With the help of analyzing the relationship between craft resource and craft design, This paper brings forward Relating model, Hierarchy model, Netted model and Oriented Object model.This paper puts forward kinds of expressing ways of craft knowledge by describing craft knowledge classifying , points out its acquiring process and form of organizing , researches dealing with technical of facing product CAPP based on O-O, realizes structure and design of based O-O knowledge managing system.Existing CAPP system or Processing information system deals with the craft resource by the way of related database or chart character which can partly solve some actual problems. There is little information about academic data model. It is known that a practical CAPP is aimed at enterprises environment and types of part. It called field CAPP. There are many kinds of craft dates which are complicated. If we can construct some fact data model catering to the kinds of craft resources, it is useful for the design of field CAPP.Through constructing mutual computer applying system which takes whole process an applying object, looks craft data and center, links craft design, craft resource managing together. It relieves heavy and repeating work, shorten cycle of manufacturing preparing, reduces expenses of craft design process, enhances responding speed and competition to market changing, realizes craft information sharing benefits to achieve integration of enterprise product design, manufacturing, running, selling and material providing, benefits to complete resource information allocate reasonably inner enterprise and among enterprises. It establishes a nice base for enterprises to carry out CIMS.
