Expand of dimensions ceaselessly as the enterprise, informatization construction turns management scientificly to enterprise implementation, establish uniform standard, establishing global consciousness is very important, and of CAXA PDM plan carry out, for the enterprise further progress provided good platform. Product data manages (PDM) be use government all information related to the product (file of spare parts information, configuration, documentation, CAD, structure, attributive) with the process (process definition, management) technology. Carry out " PDM system " the information management that the purpose depends on offerring product complete lifecycle for the enterprise, pass the height with CAPP and ERP system compositive, the product that turns to the enterprise is designed and build to run paralell develops synergic environment. Chongqing north runs quickly transmission is finite liability company (abbreviation " Chongqing transmission company " ) it is round of type car transmission that group of Chinese arms industry nods surely scientific research produces base, major is engaged in applying to crawler of for military use, annulus type panzer and army, Wu of kimono of the development of the transmission of civil and of all kinds heavy-duty car, large passenger car, transfer case, power takeoff, production, sale. To satisfy the need of of all kinds round of type armor car, heavy-duty car, large passenger car, on the foundation of transmission ZF5S-111GP/GPA and auxiliary transmission A800, the assimilation that the company introduces a technology through be opposite, absorb, already developed an archives at present for 5 archives, 6 archives, 8 archives, 9 archives, input torsion is the product of 12 kinds of transmission of 850 ～ 2200Nm. While the product of diversification is satisfying user requirement, also manage difficult problem for what the enterprise brings: Wait for a data to undertake administrative to documentation of many project blueprint, technology through manual means, cause a data to inquire disadvantageous, efficiency is low; Cannot control pull current Cheng strictly; Systematic security is poor; Information of company inside data communicates not free. To assure the seasonable sex that the information in product research and development delivers and accuracy, realize the product development of efficient, low cost thereby, improve enterprise beneficial result. Through much square survey and make an on-the-spot investigation, at the same time integrated consideration already had technology of 2 dimension CAD, three-dimensional CAD, and the inheritance that designs data and design number are seamed according to notting have compositive wait for a circumstance, chongqing transmission company chooses data of CAXA company product finally to run a system (PDM) . Plan is carried out 1, the serious analysis that company of CAXA of specific business demand celebrates transmission company demand through counterpoise, considering build " PDM system " in should compositive the product detail that its are applying, material is decided, iformation flow turns administrative system, include its to use positional sign what use to replace serial number in products plan graph, undertake contrasting will generate what needing the method of list with list with positional sign, company of transmission of final affirmatory Chongqing has the following sides to the demand of PDM plan: (1) in products plan process, generated much design data (next watches) , share staff more and liquidity is strong, because this must assure the security of data. (2) documentation amount big, type is much, lack centralized management, realize fast inquiry and data backup and the control that visit attributive not easily. (3) at present, the in founding the means that basically uses Excel form to pass assembly drawing list handiwork of product structure is typed, put in a lot of flaw: Work out list is put in a large number of same data, work of the repeatability in the job is much; The relation of component layer class of the product needs to be safeguarded by hand, expression is not intuitionistic; Component number handiwork is typed, make mistake easily; Appear one content much date or a many phenomenon of content; Because a component may be used by many products, cause component structure to revise difficulty. (4) change a method to realize efficient, low wrong rate, more seasonable project to change management to reach through the electron change requisition management. (5) inquire product property information according to the requirement, can generate summary table automatically to be used in order to offer other department. 2, the demand that decides company of integral solution CAXA passes counterpoise to celebrate transmission company undertakes an analysis, if the product changes technological process, understand graph, documentation deposit a format, the relation between each other reachs analytic graph, documentation means of going from place to place, the data accesses attributive and test and verify, divisional system module, offer PDM whole solution finally (graph 2) . This PDM system uses a client / server architecture: Server end includes systematic platform, database to serve (ORACLE) , PDM serves; The client carries functional module to include structure of documentation management, component management, product and configuration management, change management, attributive management, technical data to wait. In the meantime, PDM system is a management center with structure of the documentation of the enterprise, component, product, practice strict attributive control to them, implementation changes management, version management, pass build and maintain the relationship between these objects, assure the consistency of all data information, the graph is shown 3 times run means sketch map for product data. Graph 3 products data runs way 3, the integral solution that the system builds a basis to decide, undertake the program is developed, the systematic environment that tectonic and convenient user uses. On flow management, the electron changes blueprint examine and verify, revise, the flow that print replaced paper document be on the move, the time that reduced flow to expend, managing paper, and make the monitoring of flow task, date from became a possibility. The graph is shown 3 times to use CAXA PDM to be a client system of custom-built standardization electron flow pursues. In the meantime, counterpoise of CAXA company needle celebrates transmission company " the product detail that the hope is applying at present, material is decided, iformation flow turns administrative system is compositive manage in coordination to CAXA in, withhold the positional name that at present the company uses in products plan graph to replace serial number, the method that has contrasting will generate wanting list with list with positional sign " special requirement, undertook 2 times developing to this system (graph 4) . Graph system of 4 electrons flow pursues the tools of 5 forms for reporting statistics that ask to develop by the client 4, after system testing finishs a system to design through CAXA PDM, in this system imitate user works daily and all sorts of mode of operation, definite system design is reasonable, whether can support target business technological process move, the acceptance that gets an user thereby and approbate. 5, input history data passes a test, the system can satisfy user requirement, examination of the analysis that has user history data and changeover, validity, guide the foundation such as the data works. Since official investment runs CAXA PDM system, chongqing transmission company already built a 6T-120 in the system product radical reach a product to change model, ZF34 radical, 4100 base model the product structure tree of the product, already reached the design data related to these products plan nearly 10 thousand data such as blueprint paper to type PDM system at the same time. Of system of epilogue CAXA PDM carry out brought more benefit for the user, the work efficiency that designs the project staff not only rose 50% , reduced products plan change a time, shortened the product development cycle of 30% , and improved product quality greatly. In addition, CAXA PDM solution straightened administrative technological process for the user and united a standard, build the global consciousness of enterprise from the top down with the management of standardization, for the enterprise further progress created good administrative platform.
