Flexible the crucial technology of production system and development trend

Flexible production unit (of FMC of FMC) 　 　 come out and aborning is used make an appointment with later than FMS 6~8 year, it is by 1~2 stage machine tool of robot of machining center, industry, numerical control and stock carry the equipment that put store to form, have the flexibility that gets used to product of treatment much breed. FMC can regard a dimensions as the smallest FMS, it is FMS Xiang Lian valence is changed reach miniaturization direction development and a kind of production, its characteristic is implementation stand-alone is flexible change reach automation, heretofore already was entered popularize applied phase. 2.

Flexible production system (FMS) 　 includes 4 normally or more stage is full automatic numerical control machine tool (the) such as machining center and turning center, by centralized control system and stock carry systematic join to rise, can come true below the circumstance of ceaseless machine much breed, medium the treatment of small lot and management. 3.

Flexible production line (FML) 　 it is to be in onefold or little breed big batch blame is flexible transfer matic and in the product line between FMS of small lot much breed. Its machine equipment can be machine tool of general machining center, CNC; Yi Ke uses special machine tool or NC special machine tool, carry the requirement with flexible system to stock under FMS, but productivity is taller. It is with disperse production medium flexible production system and serial production process disperse mediumly model control system (DCS) is a delegate, its characteristic is implementation product line is flexible change reach automation, its technology already day attain mature, heretofore already was entered practical change level. 4.

Flexible production factory (FMF of FMF) 　 　 is many FMS join rises, match with automation stereo storehouse, undertake contacting with all of computer science department, use from order goods, design, treatment, assemble, examine, carry to the complete FMS that deliver goods. It included CAD/CAM, make CIMS (CIMS) is devoted and actual, implementation production system is flexible change reach automation, treatment of the manufacturing administration that achieves entire plant limits then, product and stock lay aside carry the overall of the process is changed. FMF is the highest standard that automation produces, report gives the most advanced automation application technology on the world. It is to will be made, the automation of product development and management becomes a whole repeatedly, the intelligence that controls corporeal shedding with iformation flow makes a system (IMS) is a delegate, its characteristic is implementation the factory is flexible change reach automation. 2, crucial technology 　 1.

Development of technology of CAD future CAD will introduce expert system, make have intelligence to change, can handle all sorts of complex issues. A breakthrough with current design newest technology is photosensitive stereo figuration technology, this new technology is to use CAD data directly, adopt system of scanning of computer pilot laser, three-dimensional number model cent becomes a certain number of layers 2 dimension piece record figure, press 2 dimension piece record figure undertakes optical scanning to the face of photosensitive colophony fluid inside the pool, the fluid range that is reached by scanning becomes solidify plastic, such loop is operated, chase a scanning figuration, and automatically will statified the each shape solidify of figuration is plastic agglutinate is together, need to decide data only, number can make an accurate prototype inside hour. It conduces to the rate that accelerates new structure of development new product and development. 2.

The actual application of maths of faintness of ambiguous control technology is ambiguous controller. The high-powered ambiguous controller that development goes recently has function of self-study be used to, can get new information ceaselessly in controlling a process and adjust to controlling a quantity to make automatically, make systematic performance is improved greatly, cause people huge attention in order to be based on the self-study method of artificial nerve network more especially among them. 3.

Artificial intelligence, expert ties to this day of all and intelligent sensor technology, the artificial intelligence that uses in FMS points to the expert system that is based on regulation mostly. Expert system uses expert knowledge and inferential regulation to undertake inference, seek solution of all kinds problem (if explain, forecast, diagnose, search the) such as breakdown, design, plan, surveillant, rehabilitate, command and control. The theory that because the expert is fastened,all reachs all sorts of facts can handily experience card to pass and the intellectual photograph that obtain through experience are united in wedlock, all field works that consequently expert system is FMS increased flexible. Look into future, it is a feature thick and fast with knowledge, the artificial intelligence that is a method with intellectual processing (include expert system) the technology is sure to be in FMS(especially intelligence) in having decisive effect. Artificial intelligence produces main with each passing day effect in prospective FMS lieutenant general. Use at all sorts of technologies in FMS at present, predicting what have development outlook most still is artificial intelligence. Predict 21 centuries first, artificial intelligence will be compared in the applied dimensions in FMS at present 4 times bigger. Intelligence makes a technology (each link that IMT) aims to blend in artificial intelligence production process, the intelligent activity of expert of imitate of have the aid of, replace or the partial mental work of go-between of outspread production environment. Making a process, the system can monitor his automatically to run state, in get when the outside or inner drive can self-adjusting its parameter, in order to achieve optimal job status, have organize ability oneself. Reason IMT is called future the production technology of 21 centuries. One when change FMS have important sense to prospective intelligence is in the domain of boom is intelligent sensor technology. This technology is to accompany what the computer uses technology and artificial intelligence and arise, it makes sensor is had immanent " decision-making " function. 4.

Technology of artificial nerve network is artificial nerve network (ANN) is a kind of method that network of nerve of imitate intelligence biologic has running paralell handling to information. Network of nerve of old friend labour namely tool of a kind of artificial intelligence. In automata domain, nerve network will stand side by side before long control a system at expert system and faintness, become contemporary raise a component in changing a system oneself. 3, development trend 　 1.

The popular technology that FMC will make development and application because the investment of FMC is less than FMS,this is much and economic benefits is conterminous close, more apply to the small and medium sized business with limited financial resources. What at present foreign numerous manufacturer labels FMC development is heavy. 2.

The manufacturing company of the big batch of FML 　 much breed with development taller efficiency was like the factory such as car and tractor to cause the great attention of FMS manufactory to the demand of FML. Using the machine tool of special numerical control with low price to replace general machining center will be the development trend of FML. 3.

Face is muti_function directional development is developed further by simple treatment FMS in order to solder, assemble, examine the production working procedure such as treatment of the material that reach Ban and even casting, forge holds a variety of provided function FMS concurrently. FMS is the original concept mode that realizes prospective factory and new development trend, it is the has strategic sense move that decides production company future develops a future. The FMS that reflects factory whole level at present is generation FMS, this kind of state will still meet 90 time to go down continuously, japan begins to carry out from 1991 " intelligence makes a system " (IMS) develops a project internationally, belong to the 2nd acting FMS; And truly perfect the 2nd acting FMS predicts to just be met to 21 centuries implementation. At the appointed time, intelligence turns machinery and person between will mutual confluence, flexible the ground is coordinated in the round from accept order money the overall activity that to production, sale production of this one company runs. Since 80 time metaphase, FMS achieves swift and violent progress, became the heat that produces automation almost. Because individual technology is like NC,be robot of machining center, industry, CAD/CAM, resource management and high technology on one hand develop, offerred can offer compositive the technical base of system of a whole; On the other hand, world market produced major change, by relatively traditional in the past, stable market, development is dynamic and changeful market, put to seek to live on from inside the market, seek progress, raise an enterprise to be opposite the ability of meet an emergency of market demand, people begins exploration new production methods and management mode. In recent years, the science that FMS produces as a kind of modern industry " philosophic theory " already was the place on international with the advanced mode of factory automation accepted, such OK thinking: FMS is the base that reachs production technology in automation technology, IT, the project that becomes independent each other in the enterprise before design, production is produced reach the process such as management, prop up in what the computer reachs its software below, make a complete and organic system that covers whole industry, in order to realize global trends optimization, overall cost-effective, Gao Rou sex, the intelligence that keep abreast of and wins competition to be gotten the better of completely makes a system. FMS makes the forward position science and technology that automation technology develops as current world, provided a grandiose blueprint for prospective orgnaization production factory, basically produce those who make manufacturing industry of 21 centuries orgnaization pattern.
