The design plan plan that solder outfit plan pursues is the basis that solder outfit clamping apparatus designs and foundation, need general all clamp sectional, fixed position is standard wait for clear, accurate expression. Before plan of plan of outfit of 2 dimension solder has the inherent weakness such as the relation cannot be assembled between geometry of accurate expression space and spare parts, what the design wants information not complete, cannot the very effective design that coachs solder installs clamping apparatus, cause later period easily to design a large number of modification. Now, the three-dimensional design that we use CATIAV5 to undertake plan pursues (be like right graph) , OK and accurate expression is of all kinds geometrical relation, assemble information of relation, design (include coordinate shafting, solder dot, clamp is sectional fixed position of the position and clamp means, product is standard the fixed position element with spare parts of means, clamping apparatus) , can coach later period is designed effectively, the mistake that reduced plan plan and clamping apparatus figure greatly and revise. The program that offers to leader plant pursues, we also want will thirdly dimension is changed, the purpose is on one hand the feasibility of plan of outfit of preliminary check-out solder, the design information that designs later period structure a need at the same time is compensatory and complete, with structure of convenient later period the design tries to use. 2.
Solder outfit and examine A of clamping apparatus design, PowerCopy and UserFeature (UDF) the PowerCopy that applies us to use CATIA and UDF function, the automation that implemented texture of type of a few levels is generated. Examine for example in process of clamping apparatus design, a lot of positions use identical detecting means, the member that these places need to design does work of much curved surface modelling, and the order that molding process often uses, function and even measure just the same, just be initiative input condition differs, make molding process take time arduous. We use PowerCopy and UDF to build structure of this share level now. In designing a process actually, the architect should treat the input condition such as good Point, Curve, Surface only, it is OK to choose parameter of input condition, affirmatory control next get a result quickly, undertake on this foundation follow-up structure is designed again. The operation is simple, the save labour when the province is in the process building a model of the PowerCopy that make and UDF, should notice PositionedSketch (fixed position draft) with Line, Plane directional, because the versatility characteristic of PowerCopy and UDF decided them,be opposite of geometrical element directional having very firm demand. If directional control is gotten bad, what get after the PowerCopy that makes and UDF application is likely not be the result that we hope to get, cannot execute operation even. The B, standard component that is based on knowledge engineering applies us to install the characteristic with clamping apparatus much spare parts in the light of car solder, built the standard component warehouse that accords with solder to install clamping apparatus to design a characteristic. 1) compose builds the standard component that is based on knowledge engineering. When compose builds standard component geometry, knowledge engineering of large-scale application CATIA builds modular technology. For example: PositionedSketch (fixed position draft) , ParametricCurve (parameter curve) , DesignTable (the design is expressed) , EquivalentDimensions (coequal dimension) , Rule (regular) , Check (examination) , Reactions, the standard component of the different sort that makes a structure similar unites expression to be file of a CATPart, implementation standard component is 10 kinds from a kind of change even a few kinds, make the architect is in when calling standard component, can change the specification of standard component at any time. Blend in a project to design a standard appropriately in the standard component that has structural measure, when appearing not to accord with design standard or the circumstance that exceed applicable level, the member that remind a design in time notices to correct, those who make sure standard component geometry is conveyed is correct. 2) the government that uses Catalog to have standard component and standard structure. In solder outfit and examine in the actual design work of clamping apparatus, meet those who use different level system tag a spare parts, this Catalog that uses CATIA with respect to need undertakes administrative. The member that Catalog lets design can go to the lavatory the quick standard part that search and transfers a need and standard structure. When applied Catalog has standard component government, we fall in file system, build folder respectively in the light of different level system, found Catalog respectively in each folder, be in charge of managing the standard component of corresponding standard system. According to the use function of the spare parts in each Catalog cent is a certain number of Chapter, the stepwise refinement below every Chapter in group. Found file of a Catalog below standard component total folder next, apply " AddlinktoAnotherCatalog " command, found a link to point to the Catalog of different level system respectively. In practice, we discover pattern of this kind of standard component management makes huge standard component system becomes unusual clarity and systimatic, it is the most businesslike with the most convenient management way. 3) use UserComponent to call standard component. UserComponent is CATIA - one of commands with the very formidable function in MoldToolingDesign module, can inserting standard component while have automatic and Boer operation with the Part of other (Add, Remove or Assemble) . We use UserComponent this kind of characteristic, the name is joined to be in standard component " Pad " , " Pocket " or " DrillHole " Body, reach inserting standard component while nest of the installation station that builds spare parts place automatically to need, installation the end that sells aperture with bolt Kong Jizhu with installation. The administrative tool that provides through CATIA (see figure below) Boer to these operation undertakes administrative. Raise special of commend is, CATIAV5R16 increased new function to UserComponent, make us OK more use UserComponent conveniently. The management that Zun Tu instructs these commands to be able to make us very convenient below (revise, delete, duplicate, replace etc) the Component that we call. Right plan institute shows the bolt opening that can allow us to extract automatic and Boer operation to generate in CATIA treatment module and column to sell the treatment information of aperture below, the NC that makes these hole thereby machine program. C, list and carry makings list solder outfit and examine clamping apparatus is formed by the many spare parts that be not mark and standard component, create list and workload of material detailed list artificially bigger, wrong rate is higher at the same time, serious effect manufactures efficiency. Through the BOM to CATIA the watch builds functional research, we get on look focusing in the attribute of the spare parts, changed process designing to reach the makes automatically goal of list and material detailed list basically through the client. We undertook to the attribute of standard component the parameter of knowledge engineering changes process designing is based on, keep the information of the spare parts into the attribute of the spare parts and add attribute entirely, include a date, name, amount, material, norms, standard, origin, accessory (bolt, column is sold, snail a place of strategic importance, spacer) , carry material information to wait. When the member that designing so transfers standard part, the attribute of standard component and list and information of material detailed list are generated with respect to can automatic correspondence. And to be not mark spare parts, handiwork of the member that we ask to design fills in the attribute of the spare parts and add attribute. And to be not mark spare parts, handiwork of the member that we ask to design fills in the attribute of the spare parts and add attribute. Collect these information next, generate list and carry makings list. With write the kind that keeps list completely by handiwork of the member that design before, raised efficiency and accuracy rate greatly. D, motion is emulated reach interference examination to be in before in process of design of 2 dimension graph, between product and clamping apparatus spare parts, between clamping apparatus spare parts, between clamping apparatus and solder clamp, clamping apparatus component reachs space of the athletic concern between the component, operation in-housely to wait to grant hard to decide, often appear clamping apparatus is being made after finishing, discovery is interfered or operation space is insufficient and cause revise create the situation that discard as useless even. Be aimed at this kind of state, the space that we use CATIA to offer analyses module - SpaceAnalysis interferes what examination and space concern to decide to undertaking between each Part; Use motion to analyse module, DMUKinematics undertakes athletic concerning emulation to the athletic component of fixture; To certain the part that cannot use KIN module to undertake athletic concerning emulation directly, we use the MechanismDressup function of the kinematic pair of CATIA, achieve the goal that imitate motion concerns. The application of DMU module, make the space that the spare parts concerns concerns decide become simple and easy, from go up at all the occurrence that avoided to interfere a problem, rose to design quality and efficiency considerably. Attempt of E, project is installed in the light of solder and examine the design characteristic of clamping apparatus, we generated what the project pursues the standard to undertake the client is changed, custom-built the in-house standard of my company, to tagging, the character standard that had unity, make all sorts of special marks standard Detail. Be linked together each content in the column of picture frame caption of all sorts of width of cloth and parameter especially, when applying actually, need to revise all parameter only, what can assure the caption column of all blueprint is unified, correct. Additional, solder is installed and examine the requirement of attempt of 2 dimension project of clamping apparatus will sit graticule is umbriferous come out, CATIA before version did not provide this kind of function. CATIAV5R16 provided this kind of function, the GenerativeViewStyle that is based on 3DSupport. Undertake this is planted umbriferous before, need does work of a few preparation: The file places the Xml that ① needs to make a name be WorkOnSupport3DCustumizedStyle above all to fall in Intel_aresourcesstandardgenerativeparameters catalog, provide support to this function; ② issues OptionsDraftingAdministration page " Preventgenerativeviewstyleusage " option (if pursue) cancel, activation this function. Place laying a plan is shown for umbriferous hind gotten result. Undertake umbriferous when, open the CATPart with umbriferous need first, enter GenerativeShapeDesign module, found a 3DSupport, the network interval that defines 3DSupport and reference axis name are its set current job to prop up. Enter Drafting module, build a Drawing, after clicking FrontView, appearing " Generativeviewstyle " next in drawing list choices of the toolbar " WorkOnSupport3DCustumizedStyle " , press normal and umbriferous measure next, can get the result above. Enter Drafting module, build a Drawing, after clicking Front View, appearing " Generative View Style " next in drawing list choices of the toolbar " WorkOnSupport3DCustumizedStyle " (see a picture) , press normal and umbriferous measure next, can get the result above. But very regrettablly is, this kind of function still can is opposite only at present Part undertakes the project pursues umbriferous, still cannot issue application in Product level, expect Dassault Systemes can upgrade as soon as possible. 3.
Treatment makes the three-dimensional materialization of design phase, make process fundamental data by translate into of 2 dimension blueprint three-dimensional digital-to-analogue. And the three-dimensional design software that CATIA regards CAD/CAM as unifinication, offerred many treatment module, enclothed from 2.
5D treatment machines the NC that emulates to treatment again to machine whole process to 5 axes, make design data need not pass data format changeover to enter NC directly to program phase, can extract one part to process information directly. The client that at present we are having CATIA machines a part changes application development, we believe through PKT and work out grand program can achieve partial NC of machine program generate automatically. 4, the last word is current, we are perfecting the car that is based on CATIAV5 stage by stage outfit of solder of white automobile body and examine clamping apparatus designs platform, apply knowledge engineering module to blend in more knowledge in designing platform further, improve design efficiency and design quality further, the product data that combines ENOVIASmarTeam runs a system, make 3D maths model perforative and whole design, production flow, final implementation digitlization, change a design to make without paper.
