PDM technology serves as product data management to apply in the enterprise increasingly grow in quantity, its target and function get be admissived generally, it is the technology that enterprise informatization is badly in need of, but the difficulty in applying is heavy, cycle is long, it is difficult to data is collected and be handled, devoid accuracy, rate of PDM executive success is low make general appearance. Executive PDM, the enterprise often should be done transform in great quantities, throw a large number of manpower, try to all blueprint even " standard " , even if enterprise 100% design a file by GB and travel mark also not " standard " , so how to just calculate a standard after all, how standard? Be in our country, the function with the most practical PDM of most enterprise is graph archives management, data management, configuration management, and the fountainhead that data is all and other function and the ultimate goal that the system manages, also be a methodical core, these basic functions cannot implement some PDM systems smoothly, half an year wanting a flower even 1 year of time, a lot of enterprise PDM are become be pleasant to the eye lumpish vase, or became sodden tail project. At present PDM obtains the method of data to have two kinds: It is complete handiwork is typed, hand-in-hand travel is normative. 2 it is to read take the news on former blueprint, get information through column of caption of interpret blueprints paper and detail column content, use a the same old stuff with a new label, software business development is read take all sorts of tool software, all sorts of caption column, detail column and all sorts of parameter express read take a tool, list and other form are generated by PDM system. These two kinds of methods are expedient, make PDM cannot walk out of lair. Should use research of new thinking introspection PDM, namely the commercialization of give somebody a new lease on life of product data management and PDM system. One, the distinction of PDM and requirement of level of design file administration has blueprint level is to build in it is medium with paper, on the foundation of stock of artificial classification, statistic, the design of blueprint caption column and detail column format, list is more complex, sex of the freedom that write a law is big, if do not try to transform, read directly it is very difficult to take, data is used hard. (1) data type is differ. Exactly the amount measures column, allow to keep amount and unit in detail column, and the unit has character and Chinese character, be like " circle " " set " etc. How to read extraction content to handle? (2) the setting off the beat of the label, to PDM, this some is done not have, ought not to some a lot of, some mark to cannot identify and be controlled. (3) ask elliptically differ. If design file standard,the standard component of identical GB can omit the 2nd row later, same to PDM stock title is different however. (4) size of column purpose content does not have control, if name, code name, remarks can occupy much travel. If have a plenty of annotate,go again, have a plenty of stock. (5) the uniqueness requirement of data is different, be like resistor, blueprint standard allows to be written into " resistor " and write into " resistor " , "Resistor " . PDM cannot be accepted. (6) data description means is differ, like material column certain material should be written into " name brand standard " , additionally one kind of material should be written into " standard name brand " order. This shows, "Data problem " the problem that is not a standard, however PDM and the problem that level of design file administration asks that he cannot be united. The enterprise can not finish design file management to be revised of the standard in the round, also not be the problem that short time can solve. Await a standard to edit the good luck that will make a lot of enterprises lose informatization. PDM considers that he must cast the train of thought that uses design document simply, this is full of bramble, endless and long. Want to have new courage, develop PDM function with utmost, with satisfying an industry know exactly about sth of each link place occupies a requirement to be a target, to product data and data government move and program, plan afresh, undertake product data runs give somebody a new lease on life. Make its can be satisfied already right what already had file news is successive, reduce the modification of pair of old files, want to be helpful for PDM carrying out again, assure data accord with PDM standard, shorten executive cycle. Support what future designs a file to simplify even, edit. 2, plan of give somebody a new lease on life of product data source control its plan is blueprint design file and PDM data manage departure, PDM is not from the design the file collects data, collect data from specific product data cause however. Cent of product data source is two, one is the product data source that PDM collects, one is standard stock library. Data is mixed by systematic attributive examination programme controll. 1. The data source that PDM system collects distributings existing product data to design a file in what differ, different data pattern, different descriptive kind asks to unite by PDM return to be expressed in a piece in case, we are when executive PDM, use a kind to cry " intermediate list " file, read extraction product data cause as PDM. Data format asks, one kind is to choose more general pattern, wait like TEXT, EXCEL, DWG, so that be exchanged with other software information, and can exchange with PDM. 2 it is by PDM manufacturer offers special form, can exchange with PDM system data already, also can exchange data with some kind of afore-mentioned general patterns at the same time. EXCEL format and TEXT format are better choice, but translate into a variety of database formats. Data content covered product list all content, namely all content of the product, try the content that goes against PDM management to edit. Be like " amount " the row unites a regulation to be ' number ' model, establish the acquiescent unit of belongings stock. Delete redundancy, in be like list " gross is measured " , because the total amount of PDM is automatic statistic, do not need to calculate good input artificially. Write a law to want a standard, be like " by " date is " * " or " × " , " X " , " X " etc. Add the content that produces link place need, be like " library code " etc, but the business all forms for reporting statistics lose item of expenditure to try to analyse. Statistic includes, to the computer, do not have input and classification to won't generate corresponding output, hand in by the enterprise the definition inputs output. 2. Place of business of standard stock library uses the database of yuan of material, its field, classification and descriptor join a company all need, satisfy PDM system need even, include process card need. Stay have uphold the limits of authority such as modification inquiry. 3. Data controls all intermediate list content to choose stock to the database is inputted or fill in by hand through the dot by the architect, intermediate list content by special examine tool software to undertake checkup. Before the client carries an architect to refer evaluation, check oneself with tool software, if load a relation, have without blank space, numeric type, use a relationship, have without omit, whether to exist in material library etc. Submit data to assure correct and effective, administrator of put in storage undertakes checking before put in storage, examine a tool to also can perfect general tool. Material database is controlled, belongings expects the database is safeguarded by personnel of special limits of authority, make uniform name, write law, unit to wait. 3, carry out and transfer advantageous carry out, whether transferring smoothly also is plan stand or fall important one annulus, data runs program of give somebody a new lease on life, should be helpful for data not only accurate, be helpful for carry out and applying even. Have science cut dot and way. Especially sex of big, real time runs drag in side by force software, like wanting an elephant to handle electrified task careful, affect time limit for a project and enterprise to be produced normally otherwise, cause the loss that cannot redeem even. (1) have the old product that uses value, include to already was used the part should enter PDM system. (2) in turning content of old product list into intermediate list, undertake modification by new standard, compensatory. Organizer of its integrality, accuracy, normative sex uses administrator of self check of special inspection program and put in storage to reinspect. (3) list and intermediate list processing. Intermediate list is used as PDM data source control, product list is withheld as blueprint file only in PDM system, offer concerned branch to consult. All blueprint include intermediate list to be in systematic documentation, outside dividing list other form is generated with PDM system stage by stage by use branch. (4) back up file of all put in storage is on other medium, be like library of magetic tape station, tape. Remove again decrease blueprint, can consider to cancel the list of artificial work out. (5) uniform execute electronic file to examine, assure the accuracy of electronic file and data uniqueness, prevent to provide false data. (6) when designing list, should generate by intermediate list, and make sure data is consistent, the synchronism when revising is revised. (7) column of design, detail and caption column are made by blueprint standard, examine artificially, its data is not read in PDM database. Intermediate list asks to make by PDM, use a tool to examine, files of all sorts of face of summary table paper cancel gradually. 4, file of the design after the project is finished and data management pattern (1) the project government that all files use PDM system, use person is searched through the network, browse, borrow read, scale. (2) all production all are generated automatically by PDM system with forms for reporting statistics. (3) electronic file is automatic file, paper face file and electronic file are unified. (4) all project project is generated through PDM system configuration, simplify design file, parameter is expressed kind can cancel stage by stage. (5) all list are designed no longer with all sorts of summary table. List is usable " the list intermediate " edit generation. Although the content of intermediate list is not to be read automatically,take detail column or caption column and of generation, did not have any effects to production, still can withhold pattern of traditional artificial examine and verify. Because the enterprise is to press list to organize production, the product passes the link such as batches of prototype, small trial-produce, through each link test and verify, forming the most accurate data is product list vicarious " the list intermediate " , product data full-fledged member. Assembly drawing and part drawing just are used at workshop worker to assemble production, data is in appurtenant position actually, if crucial to production link is purchased, stock extends, manufacturing plan all does not act well. Because do not collect design data, the design does not make any impacts to PDM system, version of tool of its compasses plasticity need not ask, have a browser can. It is OK to be examined artificially with the consistency of intermediate list. 5, the tentative idea research and development that optimizes further to products plan file and product data government work, become an electron for core change with paper by large quantities of quantities file and share data to be core, paper medium is accessary information, large quantities of quantities produce traditional pattern, change becomes the modern production kind that has seed profit to make a characteristic. Like sheet design, wait without accident design, collateral design, link of company products plan, data processing, demand of contented client individual character is weak the quick response ability of a mixed small lot requirement already rose substantially. But detail column is participated in 2 times by handiwork fill in, is not a system generate, cause as abhorrent as intermediate list hidden trouble. In addition design file standard to accord with, the architect should make a list that does not have practical effect more, retain management in PDM system, it is a burden really. How to perfect in if why handle production be if why handle production,being reached still the paper face file of a few need? 1. Detail column closes detail column with intermediate list 2 for one, inter list adds the serial number in column of a detail and mark label. If intermediate list expresses 1 to show. K is a library label, z assembly drawing marks, the serial number of the spare parts in be assembly drawing such as ① , j marks for hookup. Other kind with. A kind of method is to use intermediate list to replace, on design administration, among the work out after the architect finishs assembly drawing list, consign examine and verify, enter PDM system. When examining the assembly drawing that browse at the same time will corresponding intermediate list opens two windows. Because already had assembly drawing serial number, just compare detail column many somes of content. 2 it is the person that blueprint is used can build detail fence through PDM system (express) . Detail column and intermediate list consistency get controlling, because have a design,file standard allows detail column and cent of assembly drawing form piece. In actual production, a lot of architects go to the lavatory to reduce width of cloth or workshop to use, had made assembly drawing and detail column apart. The complex parameter in detail column is expressed already no point, by PDM system product configuration function is replaced completely. This kind of means and at present PDM system reads detail column, caption column, make list and etc contrary. 2. Product list cancels list, if require paper face file, replace completely by intermediate bright watch, just the pattern is different, content is some more. 2 it is by the system forms for reporting statistics is generated print. 3. The problem because standard detail column, list pattern is too mixed, fill in by hand colour is too strong, it is a design need in file standard some files. No matter be,generate by the system, its format writes a law to accord with standard of existing design file to have technical difficulty. Although be short of like content, do not affect use, but the production that be not mark makes the enterprise is in a dilemma. Need country, industry to coordinate, lead establishs the design file standard below new form. Otherwise the application technology of block up PDM. Intermediate list also needs standard of PDM enterprise and management department of design file standard, industry, to so as not to is the same as information of crossing-over of manufacturer PDM system, more be helpful for versatility of different PDM system, interchangeability, protection invests square interest, fairness of stimulative PDM manufacturer is contended for. 6, in the plan of give somebody a new lease on life of data of meaning product structure of give somebody a new lease on life of product structure data, intermediate list asks to be concerned with PDM system only, as lesser as relation of standard of industry of CAD software, blueprint. The content format of intermediate list, can define an unified shape completely, manufacturing industry is almost identical, the row is counted but augment, data type can be defined, with respect to the need of OK and contented all enterprise, also can satisfy the need that the company changes. Software firm develops general module, when carrying out slightly custom-built can. PDM manufacturer does not need a flower to be opposite for long industry survey, attention enterprise pursues every pieces paper, every kinds of format, software tool, keep law and label even, want an enterprise to list place of all sorts of forms for reporting statistics want a field only, content, intermediate list the row is counted custom-built the versatility that can improve software substantially, adaptability, dependability assures the validity of data, integrality, normative sex shortens substantially executive cycle, simplified to apply difficulty PDM but with unhook of specific CAD software, add flexibility, PDM and tool software are had can change quality, reduce newer price to change to PDM and new tool software leave a space, is not with all possible means " set prison " the dynamic sex that is helpful for the company grows and working changes, prevent system of whole industry information report is logy, be hard to meet an emergency. The use of interchangeability technology, make manufacturing industry turns industry into big production by manual mill. Interchangeability technology is in namely certain period abandons local and best, and go after what whole lifecycle and industry develop the product to optimize. Give somebody a new lease on life of product data management also will drive PDM to leave the project changes pattern, become commercialize production. Like making PDM system follows common tool software, the course is simple and custom-built and groom can consign is used. Advance PDM commercial process, reduce executive cost considerably, gain ground quickly. Raise level of informatization of our country enterprise in the round. This is the pursuit of PDM not only, also be national expectation. 7, data of last word product runs give somebody a new lease on life, it is normative data, optimize administrative system, seek the optimal division of labor in company intermediary and PDM, finish severally oneself most adept job. Developed to monarch for PDM and enterprise synchronism road. CNC Milling
