The imitate of plank spare parts as shaping the fictitious design of the mould is euqally varied. What kind of connection is there between domain of these two jobs so? At present people is devoting oneself to to develop a kind of successive fictitious CAE(CAM) flow catenary, the purpose is to will shape the design that the fictitious result of the mould uses automatically at the mould. The innovation sex of this technology: Be developed in working surface and a fictitious CAE flow catenary constructs between the design. Two kinds of viewpoints: Shape the manufacturing or of the mould is more true, development of mould of production of catenary of more fictitious flow produces or mould of production production of mould of mould design production uses the archetypal mould with more true flow inanimation and relevant spare parts to cast polish of burnish of sclerosis of milling heat treatment to carry storage to shape the Cheng catenary with more fictitious process is machined, imitate shapes kinematic imitate and the circumstance photograph previously compare imitate of mould imitate milling, the diversity requirement of automobile manufacturing industry wants to be in below the premise that assures same quality standard be developed inside short time as far as possible and production goes out as far as possible much plank spare parts. This reaction is in of ceaseless grow in quantity shape on the amount of the mould. Shape the production of the mould must varied. And have the share of extraordinary. New model is new to making shape the mould posed special challenge: Development time shortens ceaselessly. Among them key is to shorten the development time of punch mould and production time, because this are crucial to whole model project. Shorten development and two of production cycle important lever are respectively: Of synchronous mutual link cooperate with development of the job, fictitious process. Below this setting. Manufacturing mould (of FM) optimize what design and make a process appear more and more important. The standardization of mould production process makes people can more the mould production that economic ground has small lot. Archetypal mould: Graphic representation is use at producing the drawing pattern that BMW builds before 5 series car, this is the first uses design of technological process of imitate answer platform and production pattern. In the beginning that develops a process level still can undertake simple design plan is adjusted. Fictitious modelling can improve development process effectively. This kind of method that contrasts economy can between the design plan that apace chooses in different time switch, shorten substantially thereby the product develops a process (PEP) . Phase begins in the project, as the ceaseless maturity of plan, change charge to be able to increase apparently; Begin phase in what hardware develops especially. Have the aid of shapes at imitate nowadays the technology can be before mould approval very long ensure automobile body is enclothed producibility, and can better forecast spare parts quality consistently in coordination with development work. This moment can consider the material parameter of quality of such as plank and plate thickness and so on. But the influencing factor that has not consider a pattern (for instance stiffness) or the colour noisy element of the machine (for instance the deflection) of punch. The solution that the reason depends on returning neither one commerce can shape imitate calculate connection to be together with the mould. The stress that mould oneself exists and be out of shape wait for a phenomenon to make below the circumstance that the analysis to it can simplify adequately in its only (have the aid of at finite yuan of imitate) ability is significant. The unity of reseau: The imitate of the spare parts shapes (gules) the load school nucleus with the mould (black) have the aid of Yu Gengzhen fact and more fictitious component, shape the generation of the mould can describe chain of whole technological process. Develop level, it is merely in catenary of whole technological process most initial one end is very fictitious undertake. Of back-to-back move is inside methodological construction frame pull those who use level to appear. Be based on these fictitious flow measure to be able to begin to undertake imitate, can explain those who need treatment part to shape thereby means. Want comparative and actual condition to undertake be adjustmented with what the spare parts has nothing to do next, the primitive appearance that makes a pattern in this process. Undertake manufacturing the final design of the mould on the base that using the knowledge that the method constructs and gains and CAD data. Hardware development process and other and different, finished CAD designs the fictitious craft that concerns with physical characteristic no longer to be contacted. When production production mould can need not fictitious craft and bypass hardware is purchased directly. This kind of operation method is premise with much experience. In batch the actual condition according to fictitious craft manufacturing punch is mixed reserve kinematic imitate undertakes on punch. Fall in extreme circumstance (for instance to obtain the smallest shrinkage cavity) need undertakes mould imitate. Return the imitate procedure with common neither one to describe the relationship between nucleus of school of intensity of the result that imitate shapes and mould so far. Accordingly, return now cannot imitate ground describes the applied example that the mould shapes below real load. The production process that undertakes the mould designs need opposite to produce a pattern systematically and applied process have fictitious description. The technique that considers data even besides the load that appears in use phase is characteristic. Had considered the internal stress that cool and appears in caky process in design phase, this often can reduce the load that allows on mould composition substantially. Undertake to mat section imitate treatment shapes to affect manufacturing process to shape to be designed better as a result mould, the geometrical measure that needs treatment part as a result of what differ in concrete load example and material quality can appear to get power higher, ask to design new mode of operation. The catenary of processing process flow with fictitious have the aid of can reduce the application of new-style plank, the new machines craft development that simplifies to be contacted to it works. The imitate of the spare parts shapes the technology is the fixedder component in spare parts stage of production and mould design process. Simulative shapes the plasmodium that the process can get power through pressing edge mould bracket (paragraph of description is chased to substitute in imitate model) and be affected. This master piece is used on the flow with different material. In true course even the force that have the aid of considers to be decided by geometrical dimension at the drawing Bao Bi in the mould and pilot shape result. Personal classics can discover in fictitious imitate the wall is large attenuate, form fold the blemish such as turn and drawing. Because this is OK,imitate of have the aid of comes true to be affected to shaping to bring to bear on as a result in stage of production. Had begun to undertake optimizing to plank spare parts so far, because OK and fictitious imitate is medium,observation treats the influence that machines spare parts generation. In addition, the condition of oneself of such as mould, condition of punch oneself or the minor influencing factor such as the overall performance between batch punch and mould also can is opposite drawing result produces an effect. In imitate part of the need in shaping regards parameter as very carefully perhaps to have a consideration these elements. The flow catenary that after using expert applied system to consider to imitate shapes and produce a mould to design the concern between only, ability gets closing, the production course that produces a pattern in load angle opposite thereby undertakes optimizing. Now a kind brand-new the move of development shapes the method of force can become imitate model and connection of manufacturing mould design to rise. Should build the CAD model that produces a pattern on the foundation of CAD data above all. Next people will be changed to contain the reseau of element of two dimension surface finite yuan of CAD surface data that the analysis prepares to produce a pattern. Three-dimensional and successive element is used on the foundation of reseau of two dimension surface (tetrahedral) tectonic and three-dimensional reseau. The reseau develop that imitate shapes attacks structure and the bulk reseau that manufacture a tool are different. Accordingly imitate shapes is by the face, body element forms; The reseau structure of the mould and this is contrary, form by three-dimensional tetrahedral element. Main problem depends on: The job that contacts pressure to will change a pattern through what undertake imitate shapes and obtain to the spare parts apparently. And osculatory pressure is decided by condition of internal stress of drawing spare parts. Be in next the attrib border condition that the people in measure will contact pressure changeover to be mould reseau. Commercial software can offer a solution for whole technological process only, that is to say, to production the handiwork of the mould builds a model and character means additional cost. The implementation of technology measure needs to develop expert application software system. Had this kind of software to be able to use the technological process that has developed an end, and won't produce premium. Use brand-new assorted flow to be able to bring drifting profit: Current and only a kind of method is used at shaping the design of load school nucleus of the mould. Its make the optimizes the job to establish a foundation to be a spare parts treatment craft that and this kind of method agrees with only the mould component of development standard can solve the problem that appears in mould design phase to be able to undertake analytic is will coming in the light of damaged circumstance beforehand and model between build flow chain can: The Z that after before to be in specific load circumstance finishs pair of some BMW models, graphic representation builds mould bottom to undertake imitate, does to outspread and advanced finite the flow catenary of yuan of analysis can come true to use less fee below true condition carrying He to. It is clearer that digital method can compare traditional analytic method undertake building model and imitate with accurately convection Cheng. The archetypal first time of this kind of flow applies the feasibility of proof of rear cover example of BMW car at BMW car 5 series car (on E60) . Shorter mould preparation time and school nucleus schedule understand this kind of technological process special apply to industrial application. Because the imitate of the spare parts shapes,can prove: What the osculatory pressure between plank and face of mould labour tabulation can change a pattern is finite yuan on the model, can design appropriate punch at the same time, can return what carry out described as of ground of imitate of the process that pull intermediate the model additionally, by the example that load decides. Accordingly, also can cast the stretch show that the mould leaves in specific pressure load. The development that accompanying flow model shapes to how describe a mould to be in the specific load scale set in the process premise condition. This discovery plus attack in the light of develop actor chemical industry of the structure is provided can reform manufacturing tool, these achievement confirmed a trend, can implement existing technological process measure in fictitious world namely. If this one trend is able to apply successfully,can get is based on the systematic optimization technology of the computer. CNC Milling
