The administrative function of PDM

What PDM of 　 of 　 of documentation government target manages is a product the full data that includes in whole lifecycle. These data include: The treatment data of knowledge of engineering design and analytic data, product model data, product figure data, expert and inferential regulation and product. (　 of 1) original record includes assignment certificate of contract, products plan, requirement the file such as report of argument of analysis, feasibility and products plan manual. (2) designs documentation 　 to include engineering design and analytic data. In engineering design data, one part is the technical parameter of all sorts of standards that design a process and standard and product; Another part is the data that in designing a process, generates. Additional, still have information of figure of product model data, product, of all kinds test report, check and accept standard and treatment NC code to wait. (　 of 3) craft documentation technical data is the data that the place in showing CAPP system designs a process in craft is used and generates, cent is static state and trends two kinds. The technical data that static technical data basically is the standardization that points to to had been standardized on craft design manual and standard procedure; Dynamic technical data basically points to the regulation that in craft decision-making place wants, main component is technology knowledge alternative regulation and decision-making sex regulation two kinds big. (4) production manages 　 to produce what plan and management point to is the plan that produces a course to the product and management. The data in production can divide it is two kinds: One kind is fundamental data, this kind of data is stabler; Another kind is dynamic data, these data have certain timeliness, and become independent quite relatively, do not suffer other data to exist influence. No matter be which kinds of data, ask accurate, complete, its accuracy should be in 95% above, the accuracy of stock detailed account should taller, for 98% ～ 99% . (Detailed list of commonly used spare parts of 　 of 5) maintenance service, maintenance log and the demonstrative file such as use manual. (　 of 6) special file pursues like the electric principle of electronic industry or board graph mixes wiring graph, printed circuit graph of hardware plug-in unit. 2.

PDM of 　 of 　 of documentation management model afore-mentioned all sorts of documentation are divided into 5 sort model undertake administrative. (　 of 1) graph file describes the file of geometrical graph by what different CAD arises. (　 of 2) text file describes the file of function of product or component, spare parts. (The design of 　 of 3) data file to optimize component, what undertake all sorts of finite the data file of the generation such as test of moving imitate of yuan of analysis, orgnaization, test. (File of form of 　 of 4) form file includes related goods or the product of component, spare parts defines information and structural correlation information. The product defines information to include major attribute and diagnostic parameter. Structural correlation information described the subordinating relation between spare parts or component, product. (　 of 5) multimedia file reachs a product to describe a product the actual figure of each place, apply colours to a drawing can be used on the computer technical generation gives clear image picture; To complex assembly process, still can use the computer to use voice simulation, be in additional file of sound, video is made below instructor. These multimedia files reflected the information such as guideline of process of product function index, production, maintenance racily. The file can divide into processing of two kinds of methods: A kind of method is the integrality that holds a file, the data in these files cannot be broken away from with the file, once break away from,lost a sense, namely so called " bale " ; Another method is the data with medium file can extract from inside the file, these data have absolute sense, put these data classify land in relation data next, so that undertake retrieval mixing to file content statistic, namely so called " break up " . To the graphical document that different CAD system produces, respective interior has corresponding data management mechanism, PDM system also cannot not be necessary to undertake administrative respectively to each elements in graphical file, and the major attribute in code name of the whole of simply general file, name and caption column and diagnostic parameter are put in relation database to undertake administrative. Finite the yuan of analysis data document that uses program place generation often has data bulk the characteristic such as big, readability difference, have the generates the ability below the environment to be able to obtain clarity result in this data only. Accordingly, to such data file, besides having special diagnostic parameter, also can undertake administrative as a whole only to the file. In data file, the product defines the data in information to be able to serve as a kind of attribute, when inquiry, these attribute resemble key word same, facilitating user inquires corresponding relevant document quickly. Can have the data that is the same as a type through these key word classification and statistic. All sorts of technologies that record in text file ask, in changing specification, use method, besides individual and special information need has classified retrieval and statistic outside, have file government by whole commonly. Inside product lifecycle, to depict product, component and part thoroughly, all files of the product that will concern, component or spare parts rise centrally, build a complete file directory that describes a boy or girl friend, call document part or folder. Next, put them in file ark, can inquire document part, also can inquire centralized file. A file can include the file of all sorts of different types centrally. 3.

Electronic reference room 　 electron reference room (the core that Data Vault) is PDM, it builds the base in relation database system commonly, basically assure the security of data and integrality, the retrieval that supports all sorts of inquiry function. Through establishing the relevant couplet indicator on data, build different type or the connection between the product data of different compose, realize the administrative levels of documentation and connection control. The user can use the product electron documentation that electronic reference room will come to manage memory to go up at different compose medium. Electronic reference room assures the security of product data through attributive control, object-oriented database organizes means to be able to offer faster and effective information visit, realize information the process is transparent, transparent, and the information such as the physical position of the moving way that need not know application software, effective version and documentation. All data that depict product, component and part consolidate management by PDM, automatic concentration is revised. Product of product configuration management configures management (Product Configuration Management) is rock-bottom support with electronic reference room, with material detailed list (BOM, bill Of Material) is constituent core, rise all project data that defines end item and documentation connection, reach its to product object mutual the connection between undertakes safeguard and administrative. The connection between product object includes many pairs of between product, component, component, spare parts much assembly to contact not only, and the relevant data that includes other, if make data, cost data, safeguard data to wait. The product configures management to be able to build complete BOM list, realize its version control, efficient, agile ground retrieves as newest as inquiry product data, realize the completeness of product data and integrality control. The product configures management to be able to make each branches of the enterprise share unified product configuration inside the whole lifecycle of the product, and correspondence differs the product of level is defined, make corresponding product structure view, if devise view, assemble view and craft plan plan to wait. 1.

The product configures a target to manage product data resource and access to be restricted centrally. Unite the effectiveness of full data inside administrative product lifecycle. Detailed list of departmental door material (the consistency of BOM) . The product of the different type that provides user care configures information. The product with satisfactory great majority is the product that him user configures, should increase an user so optional sex, this makes configuration has to complication. Agile product data configures mode. To reduce cost, requirement spare parts is replaced agile, select standard part as far as possible, or according to local practicable substitute, will satisfy the requirement of the design with lowermost cost, its target is: Most product type, least spare parts is counted. 2.

Product structure cultivates 　 product to decompose the job of a foundation that is manufacturing industry, also be one of company main jobs in product management. In product management, the product computation to spare parts demand, namely the manufacturing planning that the product decomposes computation to be used extensively at the product, goods and materials purchases planning and new product development in. If the enterprise produces a variety of series products and product structure very complex, when the work out produces exercise to plan, the product decomposes the computation that dispute often costs. If the product is independent demand to the demand of the spare parts, fashion of summary table of part of usable product shows; If the demand of the product is relevant demand, use tree of product part structure to express commonly. Tree of product part structure is assemble systematic graph by the product, product component list (include general part, standard component, self-restrained, raw material) wait for content to comprise. Product structure tree is described with establishing record pattern, foliaceous node represents a part. This kind of graph inspected means to reflect the administrative levels concern between product, component. Had a structure to cultivate, controller can statified spread out, walk along different branch, find the data that oneself want intuitionisticly, and need not consider its physics position. Every component has its property, the material that is like a spare parts, weight, dimension, color and component are comprised by how many spare parts etc. Because object example is dispersed,the ground deposits a certain number of node in the network to go up. Close the changeover that fastens data model to realize object-oriented data model to arrive, the description of the object the 2 dimension in database of relation of attribute translate into express information, every node that the structure cultivates the component attribute related connective. Every component has relevant documentation, if the spare parts is 2 dimension blueprint, three-dimensional,the outfit of specification of model, technology, each component caskets the graph. These files are put inside file server, an enterprise may have many files server, even some file servers are in different ground. Electronic reference room is one logistic unit, its join database and file system, the relevant component on the file information that makes describe component and node organic ground joins together, realize the product data of different type to manage, form tree of complete product structuralization information. Product structure cultivates build should decide according to the administrative pattern of the enterprise. Some industries show the product of a series with a tree, also some industries show a product with a tree. The arrangement that product structure upholds also wants the person that according to the product of the enterprise complex degree decides Chi 7 ～ 8, little also want 2 ～ 3. 3.

Product structure configures management (PSM) 　 is in the enterprise, different branch needs different constituent view. If make sectional care how complete the assembly of the product and test, need what material to press what order; Management project division needs cost to analyse, use what part, need how many money. Corresponding the different level at product lifecycle, different BOM represented the news that same product defines from different point of view. The full data that PSM defines the product, include file of specification of result of geometrical information, analysis, technology, craft to wait, established connection with product structure, use door can very know some conveniently the effect that metabolic place causes. Much view provided the function that will configure BOM from different point of view for different branch. For example, production branch is in " production view " in need contains craft information, turn these information in MRP environment. Mix to the product assemble etc, can define multilayer the BOM of view. Multilayer view function is not buy of need tall grading to run skill, and the full data that all can visit a product from any BOM view. Principle of product structure configuration is chosen by user proper motion, can decide according to the version of the product and working status. PSM still supports effectiveness government, for example, according to the supply of number of date, set and supplier the case is configured, ensure production makes yield on the rails thereby. PSM can be aimed at the fixed structure of the product object of certain already version not only, still can be a certain number of the combination of version. When undertaking configuration according to appointing version, can according to the effectiveness of date or set number effective regulation configures a product, produce designation BOM list, the user edits and consult in order to offer. The user still can assign the product detailed account of the entire component that output includes all version, undertake modification to prototype thereby, make new product. It is OK that variable changes the configuration that shows a product basis but the definition of option and product configuration regulation come definitely in fact. For example, when designing car appearance face plate, same the stereo radio that the car of a model has all sorts of type can offer an alternative, different car is OK the regulation according to oneself, choose different stereo radio. If need to undertake modification to appearance face plate, design personnel can set all variable still effective. Conversely, be aimed at the BOM of car of a certain model, according to variable definition regulation can offer a precise configuration program. Flow of work of 　 of working flow management manages (products plan of main implementation of Workflow Of Process Management) and the dogging of modification process and control. Include project data refer with revise, manage and supervise, the distributinging control of documentation, automatic announcement. It is the foundation of project management, the activity of all general affairs and data dogs inside the data flow between the circumstance that main management occupies the meeting when undertaking operating to happen when an user logarithm, person and person and the lifecycle in a project. The product data classics after revising is referred, examine and approve reach register finally turn into the product data of new version. The automatic management that develops a process for the product offerred this one module to assure, support company product to develop a process to recombine, in order to obtain the biggest economic benefits. 1.

Examining and approve flow management 　 to go is to the examination of blueprint sign with handiwork on Bai Tu, and after use CAD, to computer file cannot handiwork of continue to use signs methodological course of study undertakes corrector, examine and approve those who reach control document to extend. When past handiwork signs, some leaders sign his name not only, and write even on oneself reservation opinion, so, these examine and approve a record to need to be saved for a long time, inquire in order to have. PDM uses email means to undertake referring to the file, examine and approve and extend, hint with friendly window interface each undertake examination about the leader, use an electron to record pattern permanent the reservation opinion that saves the person that examine and approve. 2.

Changing flow management 　 to change flow management is a special case that examines and approve flow management essentially. Administrative pattern examines and approve flow management together identical. Classification and retrieve system of functional 　 PDM to need to manage much data, build for better land, use with maintain these data, PDM system offerred the classified technology that goes to the lavatory quickly. It and object-oriented technical photograph are united in wedlock, it is the data that has similar character and process cent a kind, gift certain property and method, make the user can inquire the documentation, data, spare parts, object such as standard component efficiently in distributed environment. Classifying a function is one of supportive technologies that implement fast inquiry. Commonly used classification technology has: The spare parts serial number that use intelligence changes, into group technique, search / retrieve technology, spare parts to build library technology. All spare partses that classified management is production of will entire factory are designed by its and the similar sex on craft undertakes classified, form spare parts a group of things with common features. Each spare parts a group of things with common features in design and create character what all spare partses have likeness, to improve sheet, the economic benefits open up that small lot produces new approach. The encode of the spare parts is comprised by a string of character, each character is piled up on behalf of. The length of character is ten normally, much can amount to 40 ～ 50. Each a representing's specific structure and craft feature category, wait like overall figure, dimension, material, precision. Code can take a number 0 ～ 9, represent the specific feature content in each kinds of feature, be like the swing tower in appearance, blame swing tower, the distinct dimension range in dimension. Tell from in principle, the part with same code is very similar on structure and craft, can comprise a spare parts a group of things with common features. But such doing can cause spare parts a group of things with common features to count a lot of, and every a group of things with common features inside spare parts gross is not much, accordingly, short of enlarges batch, promote efficient goal. For this, should relax appropriately similar sex degree. If labour of choose and employ persons will undertake coding classified the job, already trival easy make mistake, reason is assisted with the computer aptly undertake, PDM provided this one function. Reasonable make each the similar sex standard of spare parts a group of things with common features is the key that classifies encode to obtain satisfactory result. Closely related the purpose of similar sex standard and classification and requirement, its are basic content includes design and create two fields. Management of project management project is the administration that achieves its plan, organization, personnel and relevant data in item executive process and configuration, undertake the surveillance of project movement condition, the feedback of the plan that finish. Project management is to establish a kind of government on base of working flow government. So far, project management is being perfected ceaselessly in PDM system, a lot of PDM systems can provide the state information of working flow activity only. Above introduced the function that PDM system should have. So far, the IMAN system of group class adopts Internet net and Web browser technique, class user offerred PDM to should have all function and corresponding development platform. Accordingly, PDM is everybody already generally in the action in the enterprise place self-identity. CNC Milling
