A, scale Press the scale all of the FMSs can be is divided into as follows 4 types: 1.Flexible Manufacturing Cellular(FMC) The FMC publish and use to invite ratio FMS night in the manufacturing for 68 years, it is processed a centre, industrial robot by 12 and counts to control engine bed and material carrying to save to store equipments composing and have an adaptation to process have another species product of vivid.The FMC can be regarded as a FMS with minimum scale, is a FMS to cheap turn and small scaled turn direction development and a kind of outcome, its characteristics is to carry out single machine flexible turn and automate, have already get into up to the present universal application step. 2.Flexible Manufacturing System(FMS) Usually include 4 or more full-automatic numbers to control engine bed(process centre and truning centre etc.), from concentrate the handling system of control system and material to connect, can under the sistuation that not shut down realization have another species, in process of small lot size, batch size and manage. 3.Flexible Manufacturing Line(FML) It is be placed in the quantisty not- flexible and automatic line of single or little species large quantity with medium small lot size, batch size have another of species FMS of manufacturing line.It processes an equipments and can be an in general use earth, ground to process a centre, CNC engine bed;May also adopt definite purpose engine bed or NC definite purpose engine bed, have low request at the FMS to the system flexible earth, ground of the material handling, but the rate of manufacturing be higher.It with the long-lost type produce medium flexible manufacturing system with connect the control system(DCS) of the dispersion type within manufacturing line is representative, its characteristics is to carry out manufacturing line flexible turn and automate, its technique already the day attain mature, have already got into application to turn step up to the present. 4.Flexible Manufacturing Factory(FMF) The FMF connects several FMSs, go together with to automate stereoscopic storehouse, use the progress contact of the calculator system, adoption from order, design, process, assemble, examine, deliver to hair goods of complete FMS.It included CAD/CAM, and make calculator integrated to make system(CIMS) devotion physically, realization manufacturing the system be flexible to turn and automate and then carry out whole plant the manufacturing control, product of the scope to process and the material store completely turn of the luck progress.The FMF is the tallest level that the automation produce and the reflection is most born the top of the boundary the forerunners automation application a technique.It is manufacturing, product development and management the automation of management connect into one whole, with information stream control substance stream of intelligence manufacturing system(IMS) is representative, its characteristics is to carry out works flexible turn and automate. Two, key technique 1.Computer Aided Design, CAD The CAD technique development will lead into the expert system in the future, make it have intelligence to turn, can treat various complicated question.At present design a latest of the technique breakthrough is that the light is quick stereoscopic forming technique, that the new technique be directly to make use of CAD data and pass a computer control of laser scanning system, be divided into some lamellas:3D numerical pattern a two-dimensional flake form sketch, and press the two-dimensional flake form sketch to carry on an optics scanning to the quick resin liquid surface of the light in the bath, is scan of the liquid surface then becomes curing plastics, thus circularly operate, pursue lamella to scan to take shape, and of oneself glue the each flake form curing plastics that the delamination take shape to match together and only need certain data, then can make a prototype of precision in few hours.It contributes to quickly developping new product and developping the speed of new structure. 2.Fuzzy control technique The actual application of misty mathematics is a fuzzy control machine.The high performance fuzzy control apparatus which develops recently has from the study function, can in the process of control in continuously obtain a new information and of oneself make an adjustment to the control quantisty, make system function greatly in order to improve, among them particularly with according to artificial neural net, artificial neural network, ANN of self-educated method cause people tremendous concern more. 3.Artificial intelligence, expert system and intelligence transducer technique Up to the present, the artificial intelligence adopt mostly points according to the expert system of rule in the FMS.The expert system makes use of expert knowledge and reasons logically rule progress a reasoning and solve each kind of question.(like explanation, predict, diagnose, check to seek a fault, failure, design, plan, keep watch on, repair, command and control etc.)Because expert system can simplely the theory of various fact and experience certificate super - with pass the knowledge of experience acquisition to combine together, as a result the expert system intensified for the FMS various aspect operate gentle.Prospect a future, with knowledge intensively is characteristic, with the knowledge treat for the artificial intelligence(include expert system) technique of way necessarily will have in the FMS(particularly intelligence type) decisive action.The artificial intelligence is in the future FMS lieutenant general exertive gradually important action.Used for various technique in the FMS currently, anticipate to there is the artificial intelligence of the is still of development prospect most .Anticipate till the beginning of 21 centuries, the artificial intelligence is in the FMS of applied scale will compare currently greatly 400%.The intelligence manufacturing technique(IMT) aim is in the process of integrating the artificial intelligence into the manufacturing each link, ask for help of intelligence of imitate the expert movable, replace or extend a manufacturing environment parts of mental works of the middleman.In the process of make, the system can automatically monitor it to circulate condition, while be subjected to the external world or inner excitation energy the automatic regulation its parameter with attain the best operating state, have self-organization ability.The past IMT is called make of the coming 21 centurieses technique.To the future intelligence turn 1 that the FMS has important meaning is an intelligence transducer in the realm of rapid development now technique.The items technique accompanies with the technique of calculator application and artificial intelligence but creation and it makes the transducer have insidedecision function. 4.Artificial neural net, artificial neural network, ANN technique The artificial neural net, artificial neural network, ANN(ANN) is a kind of method that the neural net, neural network which imitates intelligence living creature proceeds together to treat to the information progress.The past artificial neural net, artificial neural network, ANN is also a kind of artificial intelligence tool.At the automatic control realm, the neural net, neural network soon will be be juxtaposed in expert system and fuzzy control system and become a modern from pay to turn a composition division in the system. Three, deveolp trend The 1. FMCs will become the popular technique which deveolps and applieds This is because the FMC investment is much less than the FMS but the economic performance connect near, be applicable to the financial power limited medium small scaled business enterprise more.Numerous foreign plant house lists as FMC to deveolp currently of heavy. 2.Deveolp the efficiency higher FML Have another species large quantity the manufacturing business enterprise of the quantisty such as workses such as autocar and tractor etc. to FML of the need caused biggest pay attention to of the FMS manufactery.Adopt the price cheap definite purpose number controls engine bed to act for a process of general purpose a centre and will be a FML development trend. 3.The dynasty multi-function direction deveolp From the simplicity process the type FMS develops further to weld, assemble, inspection and Ban material process is to manufacturing work prefaces, such as Zhu and Duan.etc. and have of various function FMSs. The FMS is a realization future novel concept mode and new development trend of the works, decide to make raise of the strategic meaning of the have of prospect of the business enterprise future development Cuo.The FMS which reflects the works whole level currently is number generation FMS, in 90s this kind condition still will keep on next go to, Japan comes into force from 1991 ofintelligence manufacturing system(IMS) be international to develop item and belong to the next generation FMS;But real perfect next generation FMSs anticipate would carry out to 21 centuries.Then, the intelligence turns machinery and the persons and will blend mutually and gentlely moderates completely from accept order goods to produce, sale this business enterprise produce the full activity of management. Since the mid 80s, the FMS acquisition fast fierce development, almost became manufacturing automation of hot spot.On the other hand is because the single-item technique,such as NC, processes the development of centre, industrial robot, CAD/CAM, resources management and high technique etc. and provided to can be provided to integrate a technique foundation of whole system;On the other hand, the world market took place a graveness change, from past tradition, opposite stabilization of market, the development much changes into the dynamic state of the market , for begging existence and begging a development from the market, raise a business enterprise to the market demanding strain ability and people start investigate new manufacturing method and business model.In recent years, FMS conduct and actions a kind of sciencephilosophy and works which modernizes industrial manufacturing automate of advanced mode already for the country the top of the border generally accepted, can think so:The FMS is automate a technique, information technology and makes technical foundation, former business enterprise in mutually independent engineering design, produce manufacturing and conduct a management etc. process, constitute a complete but organic system which overlays the whole business enterprise to carry out an overall situation dynamic state under the prop up of the calculator and its software superior turn, population efficiently benefit, Gao gentle, and then win the manufacturing system of the intelligence that the competition complete victory.FMS conduct and actions nowadays world manufacturing automation technique deveolp of ex- follow science and technology, for future the mechanism manufacturing provided one arm grandiosity of blueprint, will become for 21 centuries, the mechanism is manufactural main produce mode. 6 / 6
