PDM runs medium application in technology of rigid production business

1 this production industry technology manages the current situation to serve as large state-owend enterprise, this company line of the products the level that much, product develops much, range of products the much, products plan data related to every phase blueprint archives is much, much. These elements cause technical management and manufacturing management difficulty, a bit neglect can cause craft file data and design file data abhorrent, cause do poorly done work over again thereby. Additional, in developing level, can undertake products plan data is changed sometimes, these change a lot of sections in involving this company possibly (for example: Design, craft, treatment, assemble, the sectional) such as content canal, the corresponding technical file in these branches also immediately need synchronism is changed; Additional, a lot of provisionality still can arise to design a file in developing level, those who cause product data is frequent change. 2.

2PDM managed medium action PDM to offer in this production industry technology compositive change, the products plan of network and administrative environment, main function has the synergic environment that provided to run paralell to develop and make of the product: Classification and graph documentation and product construction management, version management, inquiry management, day and job shed safety of management, system and data backup management to wait, additional, PDM is OK still undertake with the system such as CAD, CAM conveniently compositive. 2.

In system of PDM of management of 1 product construction, structure of the shape that use a tree will describe the assembly between component to concern. Among them, the node table that establish a root not product, branch node table not component (or package) , leaf node table not spare parts. Structural tree reflected product, part (package) the administrative levels between concerns. The branch that design personnel can differ in structure of edge tree shape, quick search requires product data to place. In addition, on product structure tree, the property that also can see every component clearly and to it relevant documentation. Product structure information is the fundamental information of PDM. It is a foundation with product structure information, the user can have the job such as statistic of product configuration, forms for reporting statistics. 2.

In 2 graphs documentation and process of version management design, the data that graph documentation manages includes information of the product data information of the generation in production and electronic documentation. All information in whole lifecycle mix PDM management product process. Pertinent information has: Detailed account of file of CAD/CAM/CAPP file, configuration of craft form, product, technology, stock; Relevant process has: Examine and approve, the process such as relation of flow of standard, method, access, work, orgnaization handles program and of all kinds document. Additional, the graph documentation of PDM manages the control that also offers condition of Liu Yitu form, documentation, realize the function that documentation archives governs. The meeting after Nextpage stores the graph documentation in the computer is revised for many times produces many version, the product data that gives later period is safeguarded bring a lot of inconvenience. This kind of one version manage needle Liu confused phenomenon, PDM provided version management function, undertake the version control of blueprint and condition are safeguarded effectively. The every time of one graph documentation gives systematic Liu / put in storage undertakes revise have a record, use a new working version to express not, in order to assure the integrality of data. Version by if 10 jobs version is comprised, the user has authority to appoint which job version to be effective version. 2.

3 classification and the data that inquiry manages PDM to will have similar character and process cent are a kind, same kind data and process are endowed with child same property and methodological user can pass network environment to inquire place efficiently to require data and documentation 2.

4 projects and job shed another when govern PDM function important facet is working shedding management, it can dog and control products plan is mixed modification process. PDM with day means has data government, the administrative function that provided the field such as a day attribute, resource and personnel is in a day executive process is medium, day management implements a schedule of the day, day organization, day personnel the management that wait and configuration, undertake a day run the feedback of the surveillance of condition and plan. 2.

5 systems safety and PDM of data backup management offer all-around systematic safety to control a medium. It can be the personnel that attributes different organization and part and the Liu Yi that are in different position and position to resemble, allocate different limits of authority respectively. In addition, the systematic manager that has limits of authority has the data of database of authority Liu Yi and the electronic documentation that concern to undertake backup. Should appear unusual or when needing examine and verify, the system can restore through backing up the file realizes data, avoid data to lose thereby or unusual. 2.

6 with " 3C(CAD, CAM, CAPP) " compositive PDM of the system can will of all kinds CAX(CAD, CAM, of each technology such as CAPP make a way integratedly) the data in the system has effective government, it is an ideal " 3C " compositive platform. CAPP is OK the graphical file such as the view of 2 dimension project CAD system and three-dimensional model, and a variety of with design, production, manage concerned property information to stock PDM system. PDM is OK also collect information automatically from inside the caption column of CAD blueprint and detail column, save the information that collects in data structure, in order to found product structure tree. CAPP can obtain accurate information from inside PDM system, make craft file. Same, CAM also can acquire requirement of the geometrical appearance of component, craft and treatment property from inside PDM system directly, produce correct craft document, third saves PDM system surely in, ensured CAD, CAPP and CAM data on the safe side, management is convenient, came true thereby " 3C " of the system compositive. 2.

3 executive targets and benefit are analysed 2.

3.

The day award that PDM of 1 executive target implements in the enterprise is all sorts of news that in using a compositive system to run manufacturing course, make, model of data of the design with all whole products, craft, government is built inside the enterprise, the data information that builds company level on this foundation shares platform, raise development to design efficiency thereby, shorten yield periodic. But grading will complete overall day bid: ① builds complete product data to run a model; System of ② application PDM builds the collateral work environment of sectional grade. 2.

2 benefit are analysed (1) immediate beneficial result. After this enterprise uses PDM system, from the product documentation of structural management, graph mixes version management, classification and inquiry management, the incorporate of technical level of management that day and job shed safety of management, system and data to back up 5 respects such as management promoted a business is: Shortened yield periodic, reduced reject and amount of do poorly done work over again, improved product quality, product of convenient development series. (2) indirect benefit outside the immediate beneficial result besides generation, the indirect beneficial result that the use of PDM also produces many sided for example, the administrative image that improved a business and credit are spent, make each branches inside the enterprise are used " 3C " systematic data can undertake sharing conveniently. This is received at any time for the enterprise new challenge and conform with international next dozen of good foundations. 3 conclusion are current, PDM already was in this enterprise each main technique unit and cent factory popularize application in the round. Carry out a proof, PDM is reducing product cost, reduce the respect such as reject and quantity of do poorly done work over again to have very large dominant position, and the exercise process that does not affect planned dispatching. Main advantage has: Convenient undertake cost estimation and client problem answer together, and definition is high; Improve the quality of the product and performance easily, in order to get used to the rapid change of the requirement with new market and market limits. These went to the lavatory to use further, improved manufacturing efficiency; Differ in the enterprise branch between all sorts of application software, define data to change interface beforehand, assured the standard sex of data, the data of convenient and different system is shared; The structure of engineering product is changed to the technology from approval gained real control; The correlativity of special definition, accelerated the development of products plan; Its data backup, safe control, access is restricted and file to undertake easily, assured the consistency of data and process thereby.
