For The Capp And Process Management System Development, Application Support Tools

With the market and industry environments changing increasingly, information construction is key to the development of an enterprise. The enterprise can control the flow of material, capital, information at the same time, and bring innovations to the product design, business management modes and cooperation between enterprises under the information construction. CAPP serves as a tie between the design and production in the enterprises' information construction and provides relevant data for the management. The combination of CAPP/CAD/CAM/PDM and MIS/ERP-Dhelps digitize the enterprise design, management and operation and brings the information construction to its core and provides practical proposals for solving the problems of isolated information among the enterprise.With the development of an enterprise's information construction, an enterprise will be increasingly dependent on useful and practical CAPP system. But different enterprises have different production and technology conditions, process flows and other characteristics. So it is very urgent to solve these problems and speed up the development of CAPP system to adapt it to the fast-paced, comprehensive and individualized market nowadays. And these are all the starting points of this thesis.On the basis of analyzing the methodology of the product-oriented CAPP, the conception of the product-oriented CAPP and process management system design, system information model and structure, the thesis collected a series of reusable resources from the existing CAPP system (TGCAPP system etc) and the process of developing a new system, then upgraded them to various kinds of support tools. A new target CAPP system can be developed rapidly through the customization of the support tools and proper advanced development. Then it came the new CAPP system developing mode. And the major points are as follows:1 On the basis of analyzing the methodology of product-oriented CAPP and its inherent characteristics, study the design conception, system information model and system structure of product-oriented CAPP and processing management system in order to lay a substantial foundation for the research of the support tools and enforcement of the new system developing mode later.2 This thesis studies definition of the support tools and research scope of the product-oriented CAPP and processing management system and put forward a group of reusable tools in the system and the new CAPP system developing mode based on the support tools.3 This thesis studies feasibility and means of using o-o technology to construct support tools.4 This thesis analyses the classification, the data-source storing method of different kinds of tree structures in the product-oriented CAPP system, and studies the pattern of the constructing trees. Puts forward various kinds of function operations of tree structures. They are the key-points for the support tools study.5 This thesis studies the classification of various kinds of process files' formats in the product-oriented CAPP and process file management system. As for each format of them, a constructing pattern of process file based on PowerBuilder is put forward. Develop reusable process file print module, pay more attention to resolve the interface problem between parts and the sub-systems. They are also the key-points for support tools study.6 Put forward the example of FDCAPP system development based on new system developing mode.In the end, a conclusion of the previous work and results is stated and ideas about future are proposed.
