Research On The CAPP/PDM Integrated System And Its Application In The CAPP Of Assembly-oriented Enterprise

21 century is an age of information, in which information technology has a great impact on all industries including manufacture industry. Comrade Jiang Ze Min has point out that we should insist on the industrialization driven by informationalization in the 16th National Congress of Communist Party of China. And the manufacture's informationalization is the key during the industrialization. Manufacture's development impelled by informationalization has become the current trend. During the informationalization of manufacture industry, the integration technology between all automatization units is paid more and more attention, and systems' integration becomes the important form of the industry's innovation.Under the trend, owing to its special status and effect, CAPP has a key effect during the integration of all automazition units, and its integration is a necessity. PDM is a new technology that is put forward based on Parallel Engineering and Virtual Manufacture. Because it provides an informationalization sofeware frame based on all automaziton units, PDM has become a good support system during integration. Therefore, the author researches the integration between CAPP and PDM in this paper, and that has a comprehensive and practical signification.In another hand, for assembly-oriented enterprise, which is a new mode after enterprise's re-construction under the new trend of manufacture industry, its characters of production and organization mode fit well the new trend. Thus, research on assembly-oriented enterprise CAPP should become the important direction during the research on CAPP. In this paper, according the analysis of the characters of assembly-oriented enterprise, the author puts forward and constructer an assembly-oriented enterprise CAPP system. The followings are mainly studied: Started from the methodology of product-oriented, puts forwards and constructers the CAPP/PDM integrated system frame. In that frame, analyzes its technical character, technical flow and basic function module. Puts the emphases on the automatic acquirement of product information, and researches the integrated interface mode of CAPP/PDM and the key technique of that. Started from the characters of the cooperation factory, researches the characters ofassembly-oriented enterprise, analyzes the main technical mode--assemble CAPP,and puts forward a opened, for enterprises technical design and technical knowledge accumulations assembly-oriented enterprise CAPP systems flat. Consider the opened and integrated of the system, arranges the integrated interface for the further realization in the system's second explore. Researches the BOM's two modes--EBOM and PBOM, the data realization ofthem, and puts forward the improved data storage structure. In the application system, sets up flexible ways of product information input and edit, and realizes the information conversion between EBOM and PBOM. According to the research on assemble model and assemble consequence planning, puts forward an assemble consequence planning method of layered, stepped based on PBOM.At the last of this paper, summarizes the research work, gets some useful conclusions, and puts forwards the further research thought.
