Be based on the CAPP architecture research of PDM

Based On The Analysis Of The Three Methods Of Integrated Of CAPP And PDM Software, the System Framework Of CAPP Based On The PDM Software Is Proposed In This Paper.

Keywords 　 CAPP, PDM1 　 PDM summarizes 　 PDM (Product Data Management, product data manages) it is a when in recent years development rises new technology, it devotes oneself to to shrink to the development of short sawn timber is developed and produce production cycle, reduce cost, raise quality, improvement product function, make new product fast throw on the market, gain active advantageous position of competition and advantage for the enterprise thereby. PDM technology regards a when the company restructures and develop indispensable great infrastructure as the technology, each advanced management plans the business (for example certificate of quality of international of plan of the reframing of process of battalion of already of look forward to, collateral project, CALS, ISO) carry out cannot leave PDM. In recent years new occurrence acceleration tastes the VPD that enters the market newly (draft real product to develop) technology, also support a technology to be relied on basically with PDM likewise. PDM is all information related management and product and the technology of all processes, system of a PDM should include: Data is saved and file management; Process of; of product construction management / classification of; of working shedding management and retrieve; The main function such as plan and project management [1] . The relation of 2 　 PDM and relevant technology 2.

1 　 PDM and PDM of CAPP 　 　 only then at be opposite the project is developed / the management that the product develops, the support that designs automation subsystem to the project up to now still is one of its core functions necessarily. PDM issues straton system to offer what unite centrally to run an environment to its, undertake data management of concentration and visit are controlled, pass process management to offer the job to shed control to lower level subsystem, those who realize the electronic way that devises a result is convenient examine and approve, project phase transition, the data of each respect up to date information that combines version management function to make sure lower level system acquires a product at any time, make sure synergic job is in thereby product complete lifecycle the personnel on each function part but seasonable each other communicates up to date information, know working position each other, achieve efficient, reliable compositive change move. Build jointly always charge the CIMS function unit over information and process management environment at PDM can what PDM of have the aid of unites is total control an environment, go to the lavatory and come true effectively mutual the information between is compositive, and even the function is compositive. 2.

The comprehensive management of the information of complete lifecycle of 2 　 PDM and product of support of PDM of CE 　 　 and process, and the functional limits of collateral project agrees with its. Collateral project is CAD and function of CAPP engineering design above all is compositive, expanded collateral project idea expands all designs inside product complete lifecycle, make, test, safeguard, sale... the collateral consideration of function, these collateral function systems are accepting the data of PDM and process government entirely at the same time. PDM serves as a client / the superintendency of server structure is collateral the project is all child unified information environment of the function, after can increasing particular collateral project environment to support a function, assume the heavy responsibility that collateral project supports and manages at the same time. PDM system provided the frame that supports collateral project to run and basic mechanism for function of its lower level, all of PDM of have the aid of accuses to share know an environment with information each other, of CAPP and relevant function system those who face collateral project is compositive be expected more effective, come true conveniently. Groovy function of 3 　 CAPP is analysed 3.

Project of subject CAD/ CAPP/ CAM/CAE of CAPP of 　 of environment of the information of 1 　 CAPP, function designs subsystem. It is on core position in CIMS, in the modern market environment that asks in new products plan development of frequent, product becomes company lifeblood especially. If the graph is shown 1 times, CAD, CAPP, CAM supports in CAE environment and always accuse to leave compositive job. CAPP accepts the design of CAD to regard main body as the input as a result, accuse with producing a plan to give priority to, below the vacuum seeking solution that creates environmental resource in enterprise or workshop and limitation, the design gives the procedure of the spare parts, be arranged as production and plan file of pilot program sex. CAPP is contacted with subsystem of other of interior of subsystem of engineering design automation not only close together, also design the functional system beyond subsystem to having extensive Gou Lian with the project, complete information correlation is shown at the graph 2 in. Graph 1 　 CIMS forms diagram to pursue the information of subsystem of the other inside 2 　 CAPP and CIMS is associated the 4 CAPP architecture that are based on PDM 4.

3 kinds of 1 compositive plan are based on the CAPP architecture of PDM for specific specification, the article uses software EDM with existing PDM business (Engineering Data Management) for exemple, classics development analyses EDM function and interface method, the implementation technology that involves than taking a picture is Baconian raise 3 kinds of different couple the interface plan of close together degree. The first kind of plan: Inattentive coupling type, if pursue 3. Graph structure of EDMCAPP of type of 3 inattentive coupling falls in this kind of means, groovy CAPP system and EDM operate the CAPP system that one makes be based on EDM on logic of interfacial tool EDMClient, the data control that the use person of CAPP system realizes pair of CAPP information related to EDM through EDMClient general interface, visit and examine and approve / release and the function such as inquiry. Handlers needs to be in substantial, move about makes a round trip between two systems on physics. System of CAPP of this kind of plan and EDMClient have not build the correlation on software. It cannot suit informatization, fast change the need that reachs automation. The 2nd kind, CAPP becomes program with the collect of EDM: Special and compositive change interface tool style, if pursue 4. Graph structure of EDMCAPP of type of tool of 4 compositive interface the EDM of this kind of means and CAPP compositive plan, also be groovy CAPP system not direct with EDM contact with. And with " the EDM that faces CAPP design operates interface tool environment " in replacing the first kind of plan general operate interfacial tool EDMClient. Compositive interface tool encloses the connection of CAPP and EDM amid centrally, make of CAPP and EDM compositive must not alter of CAPP system already had implementation. The implementation of interface tool needs to consider the output of CAPP and input only, do not need to understand its interior to come true deep, implementation difficulty is lesser. The circumstance when raising compositive requirement to the CAPP system that has existed particularly applicable. But, the personnel that undertakes craft is designed below this kind of means still should confront two systems (CAPP system and) of interface tool system, between the system timely move to still did not get be settlemented thoroughly back and forth, still have a lot of implicit the CAPP of the move -- EDM correlation did not realize control in software, it is the information inside influence EDM seasonable sex and CAPP are used in the potential inaccuracy that function of information visit, process management develops decides an element. The 3rd kind, become closely thick and fast (the function is compositive) means, if pursue 5. In CAPP interior each proper function handles the EDM information that blends in need and function, expand groovy CAPP system thereby, transform become " the CAPP system that is based on EDM " , this is the most close together means with implementation CAPP and compositive EDM. Of this kind of means compositive those who realized CAPP and EDM information and function is comprehensive and compositive, OK and sufficient implementation and the EDM information visit with each CAPP detail specific and relevant function and EDM process government are special change auxiliary, control the whole process that use CAPP has craft is designed in the round, conveniently thereby, implementation is the quickest share information to update control with the most convenient, voluntary process. This kind of degree that refines in order to use up need with the the the quickest, rapiddest, most automatic means and EDM data management and process management synchronism are carried out, made sure CAPP and other function system control the efficient cooperation below to move in EDM effectively, the aftereffect that made sure the project is changed tracks those who reach responsibility to check the successful implementation that wait instead. Graph this kind of means means structure of EDMCAPP of 5 close together and compositive type not only between CAPP and EDM (reach through EDM and other friend between adjacent function system) the smooth be well versed in on information, mean the proper combination of CAPP function and relevant EDM function at the same time. This has not in on two kinds of plan it is the mode with compositive information merely. When the CAPP system of type of set prescription of this kind of tight market is moving, be most efficient. Its are not worth the EDM interface function in depending on this kind of system and CAPP to concern a function but durability is poor. This kind of means applies to the situation that faces PDM to apply new form to build CAPP system. 4.

The compositive structure that the information correlation of 2 　 CAPP and EDM wants compose to build CAPP and EDM -- the CAPP architecture that is based on EDM, must analyse case of correlation of the function between clear CAPP and EDM, information. The spare parts information in technology design system is systematic input, the CAD spare parts that expects to win electronic form in technology design system designs a result -- the input that regards CAPP as the system is offerred draw-out or be the spare parts is inputted in CAPP system serve as when information consult with, because the spare parts designs information to belong to EDM of ／ of product information, attributive PDM,focus control and management, information of CAD hardware design is CAPP system and one of information with associated EDM. Craft designs the output that is CAPP system as a result, craft designs staff, under the data control that craft has designed the information such as Cheng control to should bring into EDM, project and process management and the visit control that accepts EDM, control. Procedure is CAPP system and EDM information interactive another data flows. The place on put together is narrated, the information of CAPP and EDM is being read centrally interactively take CAD spare parts to design information and all-around the respect such as the process that visit CAPP produces oneself and result information. 4.

3 architecture are based on in front structure of groovy CAPP function, the means that uses tight market to become comes true " the CAPP system that is based on EDM " , give out the architecture of the CAPP that is based on EDM. Functional administrative levels the perspective from functional administrative levels, if pursue,can construct the EDM CAPP architecture of 6. Graph system of administrative levels of 6 　 EDMCAPP notes: Because EDM takes the basic data unit of a data management and process management,be " file " , it is so in the article treatise to EDM, product data and " file " substantial same sense. If the graph is shown 6 times, EDM is reflected above all to the action of CAPP control in the user attributive to information of product of the company in visit EDM, user ID and countersign include to command attributive, file reads the much progression that writes attributive, project attributive to wait to be controlled according to safety to what EDM means one a complete set of. Through user attestation rear can operate the EDM information that will narrate below and function: General news sends and receive a function to be used at lying between the user in synergic environment interactive information; The EDM function support that provides CAPP at the same time with data visit still has examine and approve / release control, version management and all to accuse information to inquire a function, this both is implicit foundation visits fundamental function at afore-mentioned file over. Visible, bring into EDM overall environment and tighten the CAPP system that becomes thick and fast to it, look from functional administrative levels, be equivalent to be being given by afore-mentioned structures rank suit data interconnected system accuses and inquiry of the project control with current upper levels, information, message sends and receive a function. Of course, the purpose of suit depends on stratosphere / the outerest information and function. The function forms the angle from functional correlation to undertake the compose of architecture is built is based on the CAPP of EDM, the function that if the graph is shown 7 times,gets is compositive structure. Graph 7 in, "CAPP " point to part of groovy CAPP function; The information that EDM place provides and functional part; EDM FI points to EDM Functional Interface, EDM function interface, gave out " the CAPP system that is based on EDM " the EDM function that lieutenant general dissolve enters and information composition; "EDM always controls an environment " , it is to point to build at all sorts of control program in EDMVault and EDMProject, they are EDM compositive function comes true inside CAPP (data control, file is examined and approve, information inquiry) the rock-bottom structure that prop up and support features, they form what EDM function moves actually to support operating ring condition jointly. EDM FI part includes an user visit of control, file, examine and approve / release control and version management, project overall message and synergic information are examined, the message is sent and receive wait for 5 respects function. Among them: User control: Undertake login and be cancellinged administrative, under the complex attributive control that attributive of implementation user class is controlled and brings into the user EDM. User class is controlled at the same time the implicit attributive that operates to after this dominates program. File visit: Namely the file is accessed, the overall situation that realizes this locality to put store space and EDM control to fall unites the data between data storehouse to move with the come-and-go of file form, make a file controlled at EDM or from inside EDM temporary solution accuses to come out to offer editor or other end. Examine and approve / release control and version management: Archives of the project job that is electronic means, job shedding, job is controlled and manage. The project is overall of information and synergic information examine: EDM realizes its data interconnected system to accuse, the function such as project control is through build and maintaining corresponding database the watch comes true, these information are opened to the user according to booked attributive control (can inquire) . The message sends and receive: As the client / environment of cooperation of the much user below support of server structure network, much application, EDM offerred general information each other to understand a mechanism. Graph the 7 CAPP function systems that are based on EDM the article analysed 5 epilogue PDM relevant technology, the business that runs a skill in order to be based on product data is with software EDM exemple, detailed analysed the CAPP architecture that is based on EDM and compositive plan, will enclose as particular as EDM function to realize relevant administrative mechanism and functional detail, offer the functional implementation related CAPP environment, to CAPP user with as far as possible convenient support with transparent visit and control implementation, the CAPP that this has this functional requirement through fusing the corresponding function in EDM FI child go in the function, those who manage function and information is close together and compositive will come true. Make CAPP system satisfies the need of collateral project. CNC Milling CNC Machining
