MBD (Model Based Definition) the project definition that is based on a model namely, with compositive three-dimensional substance the model comes complete expression product defines information. The three-dimensional model that is based on MBD is perforative at products plan, tool, craft, make and assemble those who wait for production each link. Below design, craft and the trend that make compositive progress, the tradition serves as with card of 2 dimension craft deliver design and the method of production information to had been not coordinated with three-dimensional design environment, the technology design that the product has below three-dimensional environment has made a kind of trend. The main train of thought of method of design of the technology below three-dimensional environment is get treatment feature from hardware design model, undertake according to these treatment feature information craft plans machining next [1] . The craft of the drive of working procedure model that the person such as Tian Fujun, Geng Junhao offers devises a method, it is from the spare parts design model arrives semifinished product model is converse the treatment process that makes a part, working procedure of line of every compasses equalize, build model of a working procedure, be based on model of this working procedure to undertake finishing the program of a working procedure next. This method affects the crucial technology with automatic and decision-making craft to undertake study through be opposite, designed the three-dimensional and compositive chemical industry that is used at technology program art design system. However, the angle that this method did not use from MBD technology goes exploring machine treatment art design, regard expression as the only carrier of craft information without model of will three-dimensional working procedure. The development climate that creates medium software environment and MBD technique considering main engine of our country aircraft, use digitlization to make software CATIA and DELMIA compositive the three-dimensional chance that turns an environment to undertake is based on MBD adds craft to design a meaning great. Current CATIA and DELMIA are compositive change an environment not with machine treatment art the job such as the program forms complete MBD technology to use a system, also do not have the function that outputs custom-built three-dimensional craft documentation. In the meantime, the operation that establishs to the feature when compose builds model of three-dimensional working procedure affected the efficiency that builds a model badly also. Accordingly, the article adopts the model of three-dimensional working procedure that builds a part below compositive environment of CATIA and DELMIA, the machine that introduced drive of model of three-dimensional working procedure adds craft to devise a method; Use CATIA Automation technology to be developed be based on CATIA and DELMIA the three-dimensional machine of compositive environment adds craft to design systematic 3D-MPDS, implementation is based on the three-dimensional machine of MBD to add craft to design, formed complete three-dimensional machine to add craft to design a system. The chance that the machine of drive of model of three-dimensional working procedure increases craft to design methodological tradition adds craft to devise a method is the procedure that establishs card of 2 dimension craft, in the computer auxiliary craft plans (Computer Aided Process Planning, the diagram of 2 dimension project of model of working procedure of the scale in CAPP) system, fill in procedure / working procedure / the information such as labor situation, print finally form paper craft card. The machine of drive of working procedure model adds craft to designed a method to introduce the idea of working procedure model, expressional machine adds the intermediate feature of the process, undertake as reference with working procedure model the craft below 2 dimension environment is designed, output file of 2 dimension craft. The machine of drive of working procedure model adds craft to design the effectiveness that the method designs from craft only and intuitionistic sex consideration, the machine that did not break away from a tradition adds craft to devise a method. In MBD technology, the three-dimensional model of the product regards his as the only carrier of information, be in core position of the technology, contained all information of the product. From production angle consideration, hardware design model can consider as a course a series of treatment working procedure after undertaking to semifinished product model cutting is machined stage by stage, form [2] . In arrive by semifinished product model in the treatment process that designs a model, the spare parts experiences condition of the many craft intermediate, differentiate as craft condition with each working procedure node, use three-dimensional method to behave working procedure to machine a result to build bear the weight of machine the three-dimensional model that adds craft information calls model of three-dimensional working procedure. What the working procedure model in adding craft to devise a method with the machine of drive of working procedure model differs is, model of three-dimensional working procedure is to be based on what MBD technology builds to bear the weight of a working procedure is all the hypostatic model of information, the technology design of the spare parts and management all undertake below completely three-dimensional environment. To design methodological distinction with the craft of drive of working procedure model, the machine that the craft in article designs a method to call drive of model of three-dimensional working procedure adds craft to devise a method. The machine of drive of model of three-dimensional working procedure adds craft to devise a method but by the graph 1 express. On the foundation that this method is the technology design method in drive of working procedure model, the mobile park such as the technology program that finishs 2 dimension environment undertakes below three-dimensional environment, compose builds the model of three-dimensional working procedure that is based on MBD, make three-dimensional craft file, and can undertake with other system data is delivered. The compose of model of three-dimensional working procedure is built is the core that three-dimensional machine adds craft to devise a method. The procedure is established in the compose of model of three-dimensional working procedure in, use three-dimensional machine to add craft to design a system to finish craft to plan, make software provide geometrical feature model by digitlization again, add craft information on corresponding geometrical model next, form model of three-dimensional working procedure finally. Current, our country uses CATIA and DELMIA generally in production of aircraft main engine to undertake the product is built model and emulate. Three-dimensional opportunity has below compositive environment of CATIA and DELMIA treatment art design, use three-dimensional machine to add craft to design a system to finish the craft of a working procedure to plan above all, repass DELMIA is built in model of geometry of goods working procedure (In-Process-Model, IPM) , as associated as geometrical model craft message runs in CATIA finally. Of IPM found means to have edit type and start type two kinds. Edit the means building a model of type uses similar sex namely, through successive, Boer operation (advocate if move,divide) , parameter is revised wait for means to found IPM. Edit type IPM is specific can disobey order through be being mixed orderly again two kinds of means are built. Ordinal means, namely according to treatment order, from semifinished product one pace fashions the process of the spare parts, this process basically is mixed through acceding Boer operation comes true; Go against order pattern, be about to design a model to fill instead the process that fashions semifinished product, this process comes true through accede and be being deleted [2] . The author is used edit the model of three-dimensional working procedure that type order pattern establishs a spare parts to machine. (1) the technology design that uses three-dimensional craft to design a system to complete a process; (2) the digitlization workmanship in DELMIA (Digital Process Of Manufacturing, DPM) in, differentiate for IPM with working procedure node, in order to process the main unit that the feature regards treatment as the process, consult the craft information of process of design of the technology that finish, generate the IPM of correspondence of this working procedure; (3) undertake to IPM three-dimensional tag; (4) the information of blame geometry craft of close correlation of management and IPM, form a model of complete three-dimensional working procedure; (5) repeat above act, until all over all previous all working procedure differentiate node, build the model of three-dimensional working procedure of all working procedure in process, form complete three-dimensional craft documentation finally. Be worth what carry is, OK also below the environment that runs CATIA software only compose builds a spare parts to machine model of working procedure geometry, but such compose build the working procedure model that give to lack associated sex, and do not have the function that will identify treatment feature automatically through color. Machine add craft MBD data set to study 1 machine the content product information of data set of treatment art MBD is having data bulk big, content is complex wait for a characteristic. The bag contains a part design, craft, make, examine the design that waits for the MBD data set of departmental door information to be used at managing a part, make and examine information, make participate in the personnel that the product develops to going up to work in coordination in same product model, rose to design efficiency, assured product quality. The concept of referenced MBD data set, the article offerred machine treatment art the definition of MBD data set, it is a foundation with MBD concept and technology namely, the rally of all information that use in the process such as level is made in level of products plan phase, treatment technology program and spot. Use machine treatment art MBD data set is right machine add craft information to undertake administrative, be pair of MBD data set specialization application. Be the same as the MBD data set on common sense to be compared, machine add craft MBD data set to also be comprised by geometrical information and blame geometry information, and general MBD data set tags the project such as specification, standard specification mediumly also include in machine treatment art in the content of MBD data set. But, data set of machining craft MBD still included the machine of the spare parts to add craft information and production resource information to wait for content, provided the production resource of treatment craft course and place need in detail. A data set of whole machining craft MBD includes a part craft of design, treatment and production resource 3 parts. Among them, hardware design includes semifinished product model and design MBD model partly, design MBD model conveyed the content of the MBD data set on common sense as carrier; Machining craft part is machine treatment art the core of MBD data set, it is carrier with model of three-dimensional working procedure, convey and run the craft message of the product; Production resource part is the information that reachs the equipment such as measure with the clamping apparatus in manage a product to make a process, cutting tool. Machine add craft MBD data set to use classified management, statified administrative method, the design information of the spare parts, aircraft treatment art information and classification of production resource information maintain presence in different database. Below respective category, the associated sex that uses data undertakes counting occupying show and administrative with the form of the layer, if machine craft kind next including working procedure is three-dimensional model, procedure and craft division of labor the information of 3 respects, and the information such as working procedure was contained below procedure, working procedure fell to contain the content such as specification of working procedure number, working procedure again. The product data that 2 machine add the management of craft MBD data set and expression to be based on MBD manages a method to use a feature to uphold a law commonly. This kind of method is to point to to in using the process that build a model, differ to what product feature describes, build corresponding diagnostic tree, the means implementation that indicates through the choice classifies indication reading to product information a kind of method. Use a feature to uphold a law, the classification that can realize all pair of elements is controlled, statified show, convenient the geometrical information to the product and blame geometry information have expression. Be like all products plan data for the center with component object geometrical model, raw material, technical data if animation of operation of procedure, technology, craft is graphic wait and if manufacturing data carries out the organization such as parameter, supplier to be on diagnostic tree. In the meantime, in mode of MBD data organization, the operation animation related some craft, craft is graphic have related concern with craft parameter and its procedure data, their vest in this procedure data, the whole that carries the message such as version is consistent. Diagnostic tree is having huge advantage: Show in user use CATIA, conceal, rotate, the definition data that the commonly used function such as translation can inquire place to need conveniently or requirement; Diagnostic tree also went to the lavatory to define complete lifecycle of content and product to manage (Product Lifecycle Management, of PLM) system mix interactively compositive. In the machine that is based on MBD treatment art devises a method in, information of general blame geometry is like the product " tag a specification " , " the spare parts explains " , " material explains " , " administrative information " wait for information, and machine if the information such as procedure, production resource is with the form of parameter on the diagnostic tree of the spare parts,add craft information dominance expression, and mix geometrical information is compositive arrive same a three-dimensional model is medium. The three-dimensional machine that Nextpage is based on CATIA and DELMIA adds craft to design systematic 1 CATIA and DELMIA three-dimensional opportunity has below compositive environment the problem that treatment art design exists is in the craft of drive of model of three-dimensional working procedure devises a method in, involve compose of model of technology program, three-dimensional working procedure to build and the functional requirement of the many respects such as craft information output. Model of three-dimensional working procedure designs methodological core as this craft, other job is built around the compose of model of three-dimensional working procedure undertake. Current, three-dimensional opportunity has below compositive environment of CATIA and DELMIA the following problem basically exists when treatment art designs: (1) technology program process and compose of model of three-dimensional working procedure build process photograph depart, alternant sex is poor. Machine treatment has below compositive environment of CATIA and DELMIA art when the program, module of program of technology of general support DELMIA (DELMIA Process Engineering, DPE) independent perhaps CAPP system. No matter use which kinds of means, it is undertake in independent system, make technology program process cannot arise with three-dimensional model instant and alternant, bring inconvenience to manage and be being safeguarded of craft information. (2) compose builds model of three-dimensional working procedure to operate inconvenience, technology design efficiency is low. In CATIA and DELMIA the form that model of three-dimensional working procedure has below compositive environment builds the many functions module that needs ceaseless switch software to complete an operation, produced much repeatability work, craft designs efficiency to sell at a discount greatly, when using diagnostic tree to undertake administrative to be not geometrical information especially, affected craft badly to devise working plan. (3) the function that lacks the three-dimensional craft document with custom-built output. Although DELMIA is useful the functional module DPE that plans at craft, but the function of the three-dimensional craft document that this module lacks the custom-built format with output and close together and associated model of three-dimensional working procedure. Be aimed at above problem, design and developed a three-dimensional machine to add craft to design systematic 3D-MPDS, use at three-dimensional opportunity having below compositive environment of CATIA and DELMIA treatment art design. CATIA of 2 systems design and DELMIA software offerred rich 2 development port for the user, the user can need to have custom-built development to software according to his. The functional framework that the three-dimensional machine that is based on CATIA and DELMIA software 2 times to develop a technology adds craft to design systematic 3D-MPDS is shown 2 times like the graph. The system basically is planned by process management of information of geometry of module, blame and safeguard composition of module and craft information extraction and administrative module. Among them, process program module and craft information database join, be opposite through the instant and alternant implementation in system and database the extraction of craft information, decision-making and browse wait for an operation; Management of blame geometry information and safeguard module to pass a feature tree and database of information of diagnostic burl dot are alternant, realize pair of machine to add craft MBD data set to be not the management of geometrical information; The content that craft information extraction and administrative module take burl of feature of model of three-dimensional working procedure to nod through reading and derive model of three-dimensional working procedure, the craft that adds geometrical information and blame geometry information in custom-built format forms three-dimensional craft file in documentation. (1) process program module. The design thought of referenced CAPP system, the technology design process that has below system of will traditional CAPP introduces below three-dimensional environment undertake, the alternant operation that carries 3D-MPDS and CATIA and DELMIA software completes technology program. (2) management of blame geometry information and safeguard module. In the model of three-dimensional working procedure that is based on MBD technology, if the structure that establishs with the CATIA feature that is not geometrical information at running a model pursues 3 are shown. Hybridbodies of geometrical graph collect regards current Part object as the main target below, included a lot of specific mixture object Hybridbody, and the Parameters gather below Hybridbody object basically is used at adding property information. The characteristic that combines diagnostic tree and compose propose the functional requirement of model of three-dimensional working procedure, the management of blame geometry information of the design and safeguard module. Program top and chosen geometrical model are relevant couplet, end end and photograph of library of treatment technical data join. After model of feature of geometry of make choice of, the blame geometry information that need inquires in the database that carries from the bottom, artificial and decision-making hind add to diagnostic tree. Diagnostic burl nods delete and inquiry also is finished through this module. (3) machine the extraction that adds craft information and administrative module. Include to cultivate the extraction of information of the geometry on information of Central Africa geometry and geometrical model to the feature to the extraction of machining craft information, document [the craft information that perfects quite relatively had been developed to run a system in 1] , realize geometrical information and the expression that are not geometrical information. But, this system is the system of technology design management that faces 2 dimension environment, and operate relatively complex, suit craft to design personnel and craft to examine the use of personnel, do not suit workshop worker use, craft information extraction and memory module were added in this system for this. This module passes the couple of CATIA and technology of EXCEL2 second development, make custom-built three-dimensional craft file, and can wait for a system to PLM transmit data. Nextpage system development is based on compositive environment of CATIA V5R17 and DELMIA V5R17, the author uses Visual Basic 6. 0 development tool developed a three-dimensional aircraft 3D-MPDS of system of treatment art design, realize three-dimensional environment to deplane the fast form that adds technology program, machine to add model of three-dimensional working procedure is built and craft information manages. Use at some model plane for 3D-MPDS below double-faced three-dimensional machine machines big circle spare parts art the working process when the design. (1) the 3D-MPDS that start, open compositive environment of CATIA and DELMIA automatically at the same time. (2) the technology design that in the machine that 3D-MPDS uses below DELMIA environment module of treatment art program completes a process. If the graph is shown 4 times, the craft that machines working procedure to the first is finished to design below three-dimensional environment, it is craft information memory in the database. (3) 3D-MPDS attune takes memory to serve as reference in the craft information of this working procedure in the database, the DPM module that uses DELMIA is generated contain three-dimensional the working procedure model that tag and machines diagnostic label, if pursue,5 are shown. (4) the working procedure model that builds in DELMIA includes machine treatment only art the geometrical information of MBD data set, do not contain blame geometry information. Through 3D-MPDS blame geometry information management module completes the management that is not geometrical information, form a plan 6 show model of complete three-dimensional working procedure. According to the machine of drive of model of three-dimensional working procedure treatment art devises a method, compose builds the model of three-dimensional working procedure that gives all working procedure. (5) the documentation of EXCEL type craft that 3D-MPDS makes custom-built form, all machine of the spare parts treatment art information exports this craft documentation in, the complete three-dimensional machine that if the graph is shown 7 times,forms adds craft file, craft file can transmit data to other system. The craft below three-dimensional environment designs the last word is the heat that at present production domain studies, also be one of difficulty. The article passes the three-dimensional technology that analytic CATIA and DELMIA have drive of model of three-dimensional working procedure below compositive environment to design the issue of existence, treatment art designs the three-dimensional opportunity that offerred a kind to be based on CATIA method. This method is to use software 2 times to develop a technology to develop a three-dimensional aircraft treatment art designs a system, the technology that implemented drive of model of three-dimensional working procedure devises a method. As three-dimensional CAD technology deepen application, the digitlization design that is based on model definition has made the development trend of manufacturing industry informatization with production technology, and the three-dimensional machine of drive of model of three-dimensional working procedure adds craft to design a method to be sure to meet more and more get attention. And the key that union digitlizes production software and the efficient application that secondly second development technology implements MBD technology to will become an industry to consider gradually and direction.
