Current, the digitlization technology development of manufacturing industry of our country aviation is swift and violent, three-dimensional digitlization designed technology and digitlization prototype technology to receive development application, but three-dimensional digitlization model is done not have perforative at whole plane digitlization makes a process in [1] . BOM reframes to having very crucial effect in process of production information of translate into of products plan information, its reframe the form that the process still uses blueprint of 2 dimension project and form, face new-style manufacturing pattern, traditional BOM reframes the technology is already incommensurate digitlization develops a tendency [2] . What the article puts forward to be based on MBD is three-dimensional assemble BOM to reframe technical implementation reframes in BOM the digitlization in the process. Regard production process as medium only basis considering MBD, the data that defines digitlization to assemble craft to design with perforative product digitlization flows for the target, the three-dimensional BOM below research MBD mode reframes technology, assemble technology design to provide data base to realize three-dimensional digitlization [3-5] . Three-dimensional configuration BOM reframes the technology is three-dimensional BOM reframes the technology is the assembly that is based on MBD to assemble a model craft differentiates, model mode is assembled to fall in MBD, the form that BOM cultivates with the structure conveys product message, it is a center with component object, organize all products plan data, technical data and manufacturing data on BOM structure tree, again compose builds a product when different period BOM, main message originates the content in be based on MBD to assemble a model, the assembly that MBD assembles a model to be comprised by models of a series of MBD spare parts the explanatory note that the tree adds 0 package structures to be conveyed with the character and attribute data composition, the node of father and son that MBD assembles model of model, MBD spare parts to form arrangement with the form of number is mirrorred on BOM structure tree. According to MBD model medium craft restrains information, build products plan BOM, craft to plan BOM, production BOM, and PBOM of EBOM translate into, PBOM again translate into MBOM, namely the model reframes, the assembly that forms complete administrative levels to change craft file, form tree shape finally to assemble craft structure to cultivate, namely MBOM structure tree, will coach with it assemble production. This system builds the only basis that designs BOM, craft plan BOM, production BOM in compose is MBD assembles a model, when compose builds design BOM, attribute of the geometry in basically assembling a model according to MBD, blame geometry attribute and part manage property; When compose builds craft BOM, the others in basically assembling a model according to MBD manages property; When compose organizational system builds BOM, basically assemble the technical requirement in the model according to MBD, undertake administrative levels differentiates, generate finally can weave the production outline of procedure. Those who be based on MBD is three-dimensional assemble BOM to reframe if technical theory system pursues 1. Crucial technology 1 be based on EBOM to arrive of PBOM reframe 1.

1EBOM structure analysis reframes in three-dimensional BOM in the system, design BOM uses structure of father and son data, its advantage is: All component are mutual correlation is in in EBOM tree, consequently each component needs a definition only can at any time and place be called, make so EBOM data considerably lesser reduce data redundancy, make thereby EBOM consistency of data gets rising. In tree of EBOM product structure, of correspondence of onefold spare parts is rock-bottom node, namely spare parts number, the assembly that a few spare partses comprise of body correspondence is tall the one node of the layer, namely intermediate node, assemble number namely, and whole the root node that those who assemble body correspondence is EBOM tree, namely assembly parts node. Different component is contained on each node consequently, so node does not differ with attribute, each node is the composition such as the name that has component, type, amount. 1.

2PBOM structure analyses PBOM to also say craft plans BOM, the craft that is an enterprise designs a branch to be on the foundation of EBOM, according to information of detail of division of labor, make assemble craft course, affirmatory product assembles order, reflective product content sheds a process, press each 0 (group) the 0 package that assemble order to give out to assemble level each and the BOM data that use up an amount to form, PBOM uses structure of father and son to cultivate a form likewise. 1.

3The design BOM in the BOM system that EBOM changes PBOM to be based on MBD and node of assembly parts of craft plan BOM are identical. But node has design BOM and craft to differred at 2 o'clock below among plan BOM component. (1) reflect a product merely as a result of MBD model final position, fashion the intermediate process of the product without the definition, in EBOM structure tree, the intermediate node that is an unit with the component is met reset is become combine a node newly. If be in design BOM, the Ban gold below same number, machine add form assemble a relation, form a combination, one of becoming design BOM intermediate dot. In craft BOM, the workmanship in basically assembling a model with MBD restrains information to be a basis, the structure between the 0 package that change EBOM normally is ordinal, delimit cent is combined namely, form new structural concern, the benefit actual production at the product, the process is here medium, MBD assembles model information to be delivered as the change of intermediate node, model information itself did not change. (2) the need as a result of the design, the meeting in designing EBOM to cultivate produces nominal part, but be not made in actual production and store this component, its put be subdesign completely; In producing a course actually, as a result of the problem of craft, can produce intermediate part, the component that need as a result of what assemble namely and adds, assembling craft architect to design craft file is to appear in PBOM tree. After be being machined by production like a few spare partses, need to form a combination through soldering, spare parts factory in order to combine form to assemble a factory to refer, individual spare parts formed intermediate part. The process is here medium, model of MBD spare parts complements with raising the form of annotate information of spare parts model, these information will be arrived to design a section by feedback, design branch can add this information on the model, perfect model of MBD spare parts. The design BOM that is based on MBD arrives of craft BOM if pursue,change 2, among them A= A2 + B1, b= A1 + B2. After PBOM structure tree is formed, have engineering capability according to the enterprise (resource of ability of equipment, engineering technology, manpower) , attribute of the actual condition of each manufacturer, each component, to its child node adds craft line, the substance that adds craft line is craft detached face place forms assemble unit to differentiate for component, combination assign arrives corresponding manufacturing unit, again basis 0 (group) other information decides its produce a trend, be production BOM build provide data base. The process is here medium, MBD assembles a model to add craft course information. 2 be based on PBOM to arrive of MBOM reframe MBOM also says to make BOM, the compose of MBOM is built is according to course of craft of the component in PBOM and enterprise actual manufacturer produces type and mature type to assemble the content in procedure pattern plate to come compose builds MBOM structure to cultivate. MBD assembles a model to have the effect of core basis in MBOM, because form final MBOM,basically be child node is working procedure node, working procedure node and component attribute are close together and relevant, the work out assembles procedure information of model of spare parts of MBD of main basis spare parts. Nextpage (1) MBOM structure analysis. The assembly parts node in MBOM structure tree and PBOM are identical, father node is company manufacturer (station) , child node is paragraph, its cotyledon node is labour with working procedure (correspondence assembles procedure) 3 administrative levels, station, paragraph differentiate to be finished by industry technology office, labour differentiate to be finished by director of the technical factory manager of the workshop, room, same a model, labour it is changeless. Of node of the father in MBOM structure tree building decide according to product structure attribute, each manufacturer has the company a future life of different productivity, producer type produces same product to differ assemble. MBOM child node reachs his by PBOM father node child node, PBOM father node and other child node, outside assist the composition such as information of card of component node, working procedure. (2) PBOM changes MBOM. The production BOM in the BOM system that is based on MBD and node of assembly parts of craft plan BOM are identical. Main message includes in production BOM: The craft card content that EBOM regards fundamental data content, relevant form a complete set as staff of department of watch, craft, outside assist the component. In production BOM tree, bottom straton node is number of onefold spare parts, its father node is component number, node carrying a layer on the head is manufacturer number. MBOM course is changed in PBOM in, according to the enterprise actual production organizes means, build MBOM to carry a node on the head above all (station) , intermediate node (paragraph) , rock-bottom node (labour) , labour node is AO namely (assemble outline) will coach actual production. MBD assembles a model to undertake reset as node change, reframe MBD assembles a model to suit to produce kind actually. In assembling production actually, outside assist production BOM regards as intermediate node directly after component classics careful is signed, MBD assembles a model to wait for information without tool, equipment, cutting tool, measure, in making a process, its are necessary information, it is three-dimensional already the form that assembles procedure is deposited inside production BOM. Condition is expressed to should assemble production again the technology asks, it is to assemble the technology that the workshop offers to spare parts workshop to change, for example: Model annotate is assembled in MBD in, undertake spare parts A and spare parts B be assembled after finishing, the conference in actual production appears to undertake spare parts A finishing first, after undertaking spare parts B local finishing, undertake constructional, again odd finishing of spare parts B. It changes MBD to assemble model information directly, perfect MBD to assemble model information then. If pursue,PBOM changes MBOM 3. The 1 data that is based on VPM platform manages systematic implementation technology technology this systematic data originates ENOVIA VPM platform, products plan place passes ENOVIA VPM to mix all message related to the product all processes that concern with the product are compositive together, the information that concerns with the product includes any data that belong to a product, be like detailed account of MBD model, stock (file of configuration of BOM) , product, use all sorts of attribute data of product component, generate the EBOM that is based on MBD model, release EBOM ENOVIA VPM, the enterprise is a foundation with designing an EBOM, compose builds good PBOM, MBOM to also be stocked in ENOVIA VPM, make the enterprise makes resource of data of the implementation in the process share in design, production thereby, maintain data synchronism sex, consistency. If data preparation process pursues 4. 2 three-dimensional CAD reframe this system uses the development technology of the tool 2 development that this system uses Visual C++ to develop a tool to have CAA component technology to CATIA of three-dimensional CAD software, make CATIA of three-dimensional design software designs a tool into what attach most importance to compose system, make sure BOM each architect is in reframe below CAD platform support, begin the BOM that is based on MBD model to design the job. If specific implementation process pursues 5. Obtain interface of factory of ENOVIA V5 VPM Navigator above all, found Module and CATIAVPMdocumentMaster interface to be linked together, use CATDlg to accuse found reframe tool dialog box, get Product document, get the subclass below Product file (Product, Part) , the structure in getting a document establishs information, get model information, get model property, undertake the model shows finally. 3 three-dimensional reframe systematic function 3.

The model that 1 digital-to-analogue correlation basically supports cautious form process and structural tree node are relevant couplet, the node of father and son in including MBD model and structural tree is associated, foundation of reframing only data source is MBD model, the BOM that is based on MBD model namely reframes. 3.

The shift that 2 node build main executive BOM to change the node in the process and build, include: (1) compose builds PBOM node; Compose builds PBOM node is to procrastinate directly move EBOM corresponding node to arrive below PBOM node. (2) found MBOM node; Founding MBOM node is node of father of MBOM of layer of direct input top, stand namely a date, recycle hand is moved input and pull the way that changes photograph incorporation to found MBOM directly child node, from the MBOM that finish found. 3.

3 return a system to be finished when the architect reframe working hind or in reframe when news report having with VPM system in the process, need returns VPM browser interface, the architect can examine VPM browser interface directly, the working system that already completed will be saved automatically, lest data is missing. Archetypal system combines the research of afore-mentioned construction of system and crucial technology, compose built the three-dimensional BOM that is based on MBD model to reframe archetypal system platform, join some company the BOM of large product reframes the job, the test that had a system moves, it is namely inside this company local area network, by the group that 13 designs of 3 branches, technologist forms, the three-dimensional BOM that finished this project product reframes the job. Conclusion (1) the three-dimensional BOM that put forward to be based on MBD model reframes technology and system of construction of system, the crucial technology that is aimed at this system and systematic implementation technology undertook discussing, reframe for this BOM systematic development laid theoretical foundation. (2) developed the three-dimensional BOM that is based on MBD model to reframe archetypal system platform, had test application in process of real products plan, test and verify build between the EBOM that is based on MBD model, PBOM, MBOM, change etc reframe function. (3) this system makes EBOM, PBOM, MBOM is being built, the formal presence that establishs with product structure is in changing a course, basis MBD model reframes product structure tree, the change uses EXCEL form to achieve the kind that BOM reframes.
