Summary: Elaborated fictitious production basic idea, fictitious production core technology, and the application of fictitious production technology in manufacturing industry. Stress the feature that introduced dummy company. Current manufacturing industry forward nicety is changed, automation, flexible change, compositive change, the way that informatization and intelligence change develops, as this trend, was born a lot of advanced production technologies and advanced production mode. Fictitious the demand that make even if competes according to business market, emphasizing flexible fall with fast premise, 80 time of American put forward, as the development of computer technology and technology of website sth resembling a net, the attention of people gets in 90 time, obtain rapid development. 1 fictitious production VM is fictitious make (VM: Virtual Manufacturing) is the dynamic simulation that makes to real product, it is a kind of imitate that undertake on the computer and does not drain physical resource makes software technology. It is had build model and emulation environment, make the product plans from manufacturing process, craft, attemper plan, logistics is supplied and money is met, purchase and manage wait for a kind compositive, integrated production environment, before the production activity of real product, with respect to the function that can calculate a product and production system condition, of sex of the look up before can be being made thereby decision-making and optimize executive plan. To understand the implication of VM more meticulously, the United States is right on professional conference 3 sort VM makes following explanations: ① is central VM with the design, this kind of VM is in adding production information products plan and technology design, undertake digitlizing production on the computer, emulate a variety of production plan, evaluate all sorts of production scenes, make through emulating will optimize products plan and technology design, so that make correct and decision-making. ② is central VM with production, this kind of VM is to will emulate ability to be added in producing plan model, so that quick change an evaluation to produce a plan, examine situation of demand of technological process, resource and manufacturing efficiency, optimize production environment and production to supply a plan thereby. ③ is central VM with control, this kind of VM is to will emulate ability to be added in controlling a model, provide the emulation environment to producing a course actually, be about to machine control model is used at emulating, its target is to produce medium process actually to optimize, improve production system. Fictitious making is a kind of new production technology, it is support with IT, emulation technology and virtual reality technology. Fictitious production technology involves an area very wide, such as environment forms feature extraction of technology, process, yuan compositive, much discipline delivers data of the architecture of model, compositive infrastructure, production feature be stationed in function, decision-making support technology of tool, interface, virtual reality technology, build model and emulation technology. Among them hind 3 are fictitious production core technology. The technology that build a model is fictitious production system VMS(Virtual Manufacturing System) is the map that reality makes systematic RMS(Real Manufacturing System) fall in fictitious environment, the model that is RMS is changed, the abstraction of formalization and computerization is described and express. Of VMS build a model to should include: Produce the information architecture of model, product model and craft model. Manufacturing model but description of reduce static state and trends describe two aspects. Static description is the description that points to systematic productivity and manufacturing character. Dynamic description is to point to the whole process that forecasts product production on the foundation of foregone system condition and demand character. Product model is production process in, the gather of model of of all kinds and hypostatic object. The information that at present product model describes has the static news such as feature of figure of product structure list, product. And to VMS, the overall activity in wanting to make the product carries out a process is compositive, must have complete product model, so fictitious making the product model below is onefold static feature model no longer, it can extract a product to carry out through the method such as map, abstraction in the connection of products plan attribute that the model craft model that each activity place requires produces craft parameter and effect the function rises. Produce the interact between model and product model in order to react. Craft model must have the following function: Computer technology is emulated, model of production data table, production program, statistic and physics and mathematical model. Emulation technology is emulated even if applied computer is passed to complex actual system abstraction and simplify form systematic model, run this model on analytic foundation next, get fastening unity the statistical function of series thereby. Because copy is the research technique that is an object with systematic model really, and noninterference produces a system actually, emulate the fast operation capacity that can use the computer at the same time, the production that in be being produced actually with imitate of very short time, needs for a long time is periodic, can shorten accordingly decision-making time, avoid the waste of capital, manpower and time. The computer still can repeat emulate, optimize executive plan. Emulated basic measure is: Study systematic → collects data → to build systematic model → to emulate algorithmic → to build emulation model → to run emulation model to → outputs a result and be analysed certainly. The product makes a process emulate, but reduce production system simulation and treatment process are emulated. The product development in fictitious production system involves a product to build imitate process of true, design to plan to emulate, design thinking process and design are alternant behavior is emulated etc, so that undertake evaluating to designing a result, implementation design process is inchoate feedback, decrease or avoid products plan mistake. Treatment process is emulated, include cutting process to emulate, assemble a process to emulate, examine the process is emulated and solder, forming, cast emulate etc. At present independent development rises two kinds of afore-mentioned emulation processes, still cannot compositive, and should build in VM face the unity that makes whole process to emulate. Technology of virtual reality of VRT(Virtual Reality Technology) of virtual reality technology is to be in to improve the interactive mode of person and computer, of the generation in raising computer maneuverability, it is to use computer graph system integratedly, all sorts of indication and the interface equipment such as control, generate on the computer but interactive three-dimensional environment (call fictitious environment) in offer be enmeshed sensory technology. Reach all sorts of interface equipment composition by graphical system, with will produce fictitious environment and offer be enmeshed feeling, and the be called by a joint name of computer science department that alternant sex operates is VRS(Virtual Reality System) of virtual reality system. Virtual reality system includes handlers, machine and man-machine interface 3 main essential factor. It raised the harmonious rate between person and computer not only, also make a kind of powerful emulation tool. Use VRS to be able to undertake dynamic imitate to real world, pass the alternant input of the user, revise fictitious environment in time by output, make the person produces be personally on the scene be enmeshed feeling. Virtual reality technology is one of crucial technologies of VM. 2 VM applies VMT(Virtual Manufacturing Technology) of fictitious production technology to win successful application in the domain such as plane, car above all in manufacturing industry. American Boeing (Boeing) company is in process of design of model of 777 new-style planes, use VMT and three-dimensional model to undertake piping wiring wait complex the imitate that rigs a process scores a success. At present VMT application is in the following respects. Dummy company builds fictitious business, because each enterprise itself cannot satisfy market demand alone,having a the mainest reason among them is, meet market challenge. Accordingly, to answer the demand of the market quickly, around new product development, the existing resource that uses different zone, different company or the plant that order differently, reorganize a new company. Before this company is moving, must analyse combination best, whether coordinate carry to go, wait to casting postpartum risk, interest allocation undertake assessment. This kind of couplet makes a company call dummy company, perhaps make dynamic alliance, it is a kind of dummy company, it has compositive sex and actual effect sex the economy of two big characteristics is hypostatic. The feature of dummy company is: ① business district is changed dispersedly. Dummy company orders goods from the user, products plan, component is made, and assembly is assembled, sale, management can part by the enterprise at different district, make by couplet of mutual benefit of contracted mutually beneficial, undertake ground of different ground design, different is made, different ground management. ② industry organization is changed temporarily. Dummy company is the child with changeful market. To get used to the change of market environment, the enterprise organizes a structure to also want to mirror market trends in time, dummy company pays attention to short-term profit. Change when product direction, when the interest is changed between allied associate or enterprise pursuit target is changed, the enterprise should adjust constituent structure, perhaps disband instantly, the dummy company with new new reframe. ③ enterprise function is not complete change. A whole industry, should have from business management, design, make wait for complete all function to market sale, after service all the time. But do not need orgnaization function in dummy company complete, it uses outside force to undertake assorted mixing with all sorts of means compositive. Because dummy company is dynamic and allied form, break through the corporeal bounds of the enterprise, use exterior resource to achieve the market goal of the enterprise quickly. Traditional outside assist treatment is a kind of primitive dummy company action. ④ business information is shared change. Form one of postulate of dummy company, comprise the computer Internet between business associate namely. According to particular case, can be internet, local area network or enterprise interior net, seasonable channel communication ceases, include products plan, make, the information such as sale, management, these information are with data the form expresses, in the computer environment that can distributing to differ, share in order to realize information natural resources, make sure height of departmental door foot coordinates dummy company, in the market fluctuant condition falls, ensure the company is the biggest integral interest. The main base of dummy company is: Build the business on base of advanced production technology flexible change; Digitlization product is made on the computer, from the concept the design arrives to realize a product finally of whole process fictitious make; Computer network technology. 3 afore-mentioned content are to make the requirement with dummy indispensable company. This plants dummy company advanced production mode, had moved in the partial enterprise of advanced country. For example the dummy company that company of American Ultra Comm is manufacturing electron product, there are many 60 in American each district, the fictitious report subclass that the employee of thousands of comprises is round, company itself has a few employee only, this company is used be designed dispersedly and make way, different product chooses different company, the economy that relies on network technology composition is hypostatic, achieve market goal. Set in the Xin harbor company of Hong Kong like headquarters again, it is an internationalization enterprise, in order to make the telecommunications product that sale phone gives priority to, headquarters is engaged in new product development, development, sale and management waiting, in domestic Xiamen special economic zone Hong Taike learns industrial garden to make. In face changeful market demand to fall, dummy company is had accelerate new product to develop rate, improve product quality, reduce manufacturing cost, answer the demand of the user quickly, shorten the advantage such as product production cycle. Accordingly dummy company is the army that answers market demand quickly, can hold for the enterprise in trade war good luck and bring an advantage. Fictitious products plan for example the appearance design of plane, car, whether does its appearance accord with aerodynamics principle, the obstruction in athletic process, the rationality of composition of its interior structure. In design of complex pipeline system, use fictitious technology, the architect is OK " enter among them " undertake conduit is decorated, can check whether produce interference. In the fictitious products plan on the computer, not only can improve design efficiency, and the problem that can discover the design is medium as early as possible, optimize the design of the product thereby. For example American Boeing company invests 4 billion dollar to develop Boeing 777 jet-propelled plane, began to was used only in June 1994 3 years from October 1990 time of 8 0 months completed development, test-fly succeeds, throw operation. Boeing company is in the world dispersedly the technical personnel of each district is OK from 777 planes the attune in the component of tens of thousands of takes up the post of He Yi to plant go up in the computer observation, research, discuss, all component all are three-dimensional and hypostatic model. It is thus clear that fictitious products plan gives an enterprise brought benefit. Fictitious product makes applied computer emulate a technology, of ordinal to the treatment method of the spare parts, working procedure, tool choose, of craft parameter choose, treatment craft sex, ship-fitter art sex, cooperate between cooperate gender, join the motility of the join sex between, moving link all can build a model to emulate, can discover treatment flaw ahead of schedule, discover the problem that when assembling, appears ahead of schedule, can optimize production process thereby, improve treatment efficiency. What product of fictitious production process produces a course is reasonable make, stock of manpower resource, production resource, stock, production attempers, the program design that produces a system, all can emulate through the computer undertake optimizing, still can be opposite at the same time manufacturing system undertakes dependability is analysed, undertake analytic forecasting to producing the capital of the process, undertake analytic forecasting waiting to product market, be opposite thereby the reasonable configuration of manpower resource, production resource, to shrinking short sawn timber produces cycle, reduce cost import great. The place on put together is narrated, fictitious production technology can bring a lot of benefit in the application in the enterprise. Fictitious products plan can improve a design quality, optimize product function, shorten the design is periodic. Fictitious product is made can improve production quality, optimize process, shorten production cycle. Fictitious production process can optimize resource configuration, content to shed management, shorten production is periodic, reduce manufacturing cost. Dummy company can strengthen a business flexible, satisfy special requirement of the client, form the market competition advantage of the enterprise. Our country is fictitious the research of production technology just starts, of the system, comprehensive research had be notted begin, the theory that still keeps in abroad at present digests the union with domestic environment to go up. Want us hard to create a better base only, the application that fictitious production technology is in our country enterprise already by a definite date is not far. CNC Milling
