Current Chinese engineer is product data management to what (PDM) may be a little unfamiliar still, say product data management incorporated a lot of concepts that conduce to pair of product data and product development process undertaking administrative and technology simply, manufacturer people can track a product through PDM system whole life is periodic (include development, design, make, support and safeguard) all data that need to be used. PDM system has 4 basic functions (or mode) , configure management, process management, structure and memory library namely. Configuration management: Configuration management passes program, regulation and technology to undertake controlling to the product, it resembles " adhesive " , designing, make and component, file and data maintain to change synchronism in supportive process. The key of configuration management includes below 5 parts: · identifying undertakes to product and component structure divisional · coordinates component, file and data to change the connection ligament · between the version in whole lifecycle mixes modification control product change administrative · condition to record component and the position that change application record and report · examine and verify make entire component maintains: Process management uses processing an organization or branch and another between the method that exchanges data, so that take unified action according to regulation of a flow, it has 4 crucial essential factor: Share personnel and its part; The information kind that every participator place needs; Win the way of information; Need adopted action and the influence to working flow. In the development process of a product, can make part of a lot of constructions, and be revised even, examination, check and approve, these are carried out by different person, do possibly many times even sometimes. Because these alternate reduplicative work,changing, the design that so an engineer costs a large number of time and master piece of essence of life to go out is very easy be in with another person the job of other part is afoul. Numerous PDM system uses the method of a lot of technologies that can use currently, the graphical interface that includes to come true through the network, email and file method, for example you can be in the system set a regulation, before preventing an engineer to get approving in all component, sign agree to undertake assembly. Structure: The structure calls material detailed account again normally (BOM) , but the difference with there also is a few significant between both. BOM is the document that contains all and necessary production information, it will yuan parts of an apparatus presses project number (or inquiry date) make it is expressed. BOM is due below a few content: Yuan parts of an apparatus (include number of specification, manufacturer and referenced symbol) ; Amount; Norms; Referenced file (map of bag vinculum road and test measure) . The structure is to point to yuan of parts of an apparatus and yuan parts of an apparatus reachs the relation between yuan of parts of an apparatus and file, all rows have a link to arrive repeatedly on its specification book in yuan of parts of an apparatus on BOM, all component (yuan parts of an apparatus) it is taller the one part of one class component, unless a certain component is an independent project. If together advocate board the design is become with connector join stores module, must want to come to this distinguish with the structure advocate board the memory module that is use 1M or 2M memory module. Memory library: Memory library is primitive data (or original document) safety deposits a system, once had been put later, its integrality can get assuring, because all changing,be monitored, control and change processing into travel file. The primitive data previously imprints in can duplicate on agency (it is to get together normally fat film or kraft) , sign approval by the engineer this blueprint / component can have production, protect existence to design a section inside, a copy is made when need is used (blue print) . As the use of CAD system, primitive now data is saved with electronic method, such those also consult easily in the person besides design branch. What profit does PDM have? Was to shorten above all the face city time of the product, this is the benefit with PDM the mainest system. The time that the product puts the market on basically accepts 3 elements restriction, among them one of time that are the task that finish, if the project designs time. Cause of time prolate part is being caused here is so called " repeat a design " syndrome, flower of the member that design is solving the time on the problem that already had been solved by others is breathtaking normally, the time that because people thinks generally,designs again wants more off-the-peg than searching design shorter. The 2nd advantage is the task between " invalid time " fewer, say this includes information to deliver simply, search, the time that obtain or awaits blueprint to copy and so on, also may be the time that awaits someone feedback news, in because the design may be being put in its,waiting for transaction file to place, wait to handle. The 3rd it is what to need time of do poorly done work over again little. The charge that changes place earlier in designing a process to involve is less, when the product is about to have production, make again change cost to will increase considerably, because this cooperates with,the key of the design is to participate in personnel to often must be communicated and share its to devise concept and point of view in whole design process entirely. PDM system can pass below a few means are managing time: Data can get the rate that accelerates the task to finish thereby immediately when need; Support works to manage with the task in coordination; When design task is put in waiting for transaction file to place, can inform relevant personnel of seasonable processing, decrease " block " ; Allowing to visit all and relevant data and assure it is newest version. The everybody in working project uses same data and data always is newest this are very important. After having PDM, if you are to use original document to have the job, you can believe firmly to it is exclusive; If you see a referenced copy, you also know it is the copy of newest source file. Memory library made sure all and original document is safe and accurate, although people works at the same time, the design that also won't have antilogy appears. PDM system can make a project team can build many version to any designs hand-in-hand travel is safeguarded, after this means a design to change, need not fear foregoing version are met lose or delete. Every time edits should sign before release and tag date, any not certain factors of existing design offer purify to change an examination thoroughly to dog system. Spend too much time in brand-new there is particular risk on design method, if this method won'ts do, cost very will tall. DPM reachs venture share on someone else body, make data can send quickly in right hand, because this is more adjacent,provide creative design process at. At the same time it allows an individual to hawk its viewpoint to someone else, encourage whole group to seek the means that solves a problem together, make everybody knows everybody is paying close attention to same question. The reason that the product develops a project to often be deferred is not plan badly at the beginning, however day-to-day work loses control. Why to meet such? The snowball of mass data elephant that arises in executive process because of the project is euqally rapid grow in quantity, was head and shoulders above traditional project to manage ability category of the technology. Because the product puts in market time limit to shorten, the product is abhorrent increasing with the possibility of do poorly done work over again. PDM system assures to undertake strict monitoring to concerning data, ensured the control to the project, be released through automatic data additionally and electronic autograph program, still make project control gets strengthening further, the task that makes a plan good thereby is impossible to be ignored, conceal or forget. Does the influence PDM that designs staff to PCB design personnel to He Ying rings to PCB? A when regard a project as the group, PCB designs personnel to design and assembled a respect in bat to make a lot of works, the product that at the same time he also needs to so that the design comes out,seek advice from the opinion of other domain expert has producibility, and the product is whole system function is normal, for example he can be in a component board the positional information that go up sends others, affirm won't with other component produces conflict to wait a moment inside the system. The system may design personnel design by PCB partly, likely also and whole project is circuit board assemble, it is which kind of circumstances no matter, can use PDM system module, PDM concept is used to coordinating component, structure (namely BOM) is made, data switch and data save very useful part. The document that PDM system place needs can pass CAD system to arise more very much, more and more CAD suppliers raised PDM character in their system, if edit of version dog and output a format to wait. Although these are right the file that manages CAD system generation is first-rate, but not complete still, because its mishandle is other the data of the format. Want to make data of a product complete, still need to have file of a lot of text (working specification and order demand) with spreadsheet case (test data is reached bad taste analytic) . What should notice additionally is not be entire line has attributive to enter whole CAD system to examine blueprint in the person that sends exterior and interior, because this is all,the blueprint that need delivers should be one kind reads taken file form easily, so that those need,the personnel of data can be read. Some companies think a whole PDM technology system is very expensive, want hundred thousands of dollar sometimes, the program that because this majority uses the PDM in CAD system,oneself develop, pass for example " autograph loop " when the software that transmits data, new design is released, file carbon, the option function in use email and offer good copy to wait to the supplier only. It is very important to have a bit, although do not need whole PDM technology system,be, be in a few places to also should method of some kind of PDM can be used. CNC Milling CNC Machining
