Flexible production technology is the application that computer technology is producing process and its equipment to go up, be create microelectronics technology, intelligence technology and convention technical confluence to be together, basically include flexible production unit, flexible production system. The automation of introductive tradition produces a technology to be able to improve manufacturing efficiency significantly, however its limitation also clearly, the demand that the small lot in cannot suiting well namely produces. As the development of production technology, especially automata technology, CNC Machining technology, industrial robot technology the swift and violent development that wait, flexible production technology (FMI) emerge as the times require. 1 flexible production technology is so-called " flexible " , it is to point to production system (enterprise) get used to ability to a kind of systematic interior and external environment, also be the ability that shows production system can get used to a product to change. Flexible can divide for instantaneous, short-term and long-term and flexible. Instantaneous is flexible be after pointing to equipment occurrence malfunction, the ability; that remove trouble automatically or machines spare parts move to the proceed on another equipment is short-term and flexible it is to show the system is inside brief period, get used to the ability that machines object change, include to mix the ability; that undertakes machining spare parts of 2 kinds of above in aleatoric period long-term and flexible it is in showing the system is being used for a long time, can machine the ability of all sorts of different spare partses. Up to now, flexible still try can qualitatively to analyse only, shang Moke learns to quantify index practically. Accordingly, every is had afore-mentioned 3 kinds flexible one of features, production system can call the automation that has stock or iformation flow flexible production system. Flexible production technology is the application that computer technology is producing process and its equipment to go up, be create microelectronics technology, intelligence technology and convention technical confluence to be together, have automation, flexible change, efficient characteristic, it is the basic and unit technology that at present automation makes a system. 2 flexible production unit (FMC) is flexible production unit (FMC) is to be on the foundation of machining center, the automatic makings library that increased memory workpiece, automatic treatment system that carries systematic place to form. FMC has more all ready monitoring function, include cutting tool attaint to detect, life detects and machine man-hour to monitor etc. The full treatment of workpiece is commonly finish on a machine tool, commonly used at casing kind the treatment of complex part. Graph the FMC that 1 have tray to exchange a system to form to match. Tray makes up clip has work, in machining a process, it and workpiece flow together, similar normally along with travel clamping apparatus. The transportation that annular workbench uses at workpiece and intermediate memory, tray procrastinate by the annulus catenary of inside on annular slideway move and circumgyrate, every tray on have address identification code. When a workpiece treatment ends, numerical control machine tool issues signal, the work that by tray commutative unit will process (include tray) procrastinate to be in to the room of circumgyrate stage, turn to next assemble and unassemble labour, will wait for at the same time add workpiece to push to machine tool workbench locate treatment. Graph the 1 FMC FMC that contains tray to exchange a system is comfortable the production at workpiece of much breed, small lot. FMC has dimensions small, cost is low, facilitate patulous wait for an advantage. But the degree of information system automation of FMC is inferior, treatment flexibility is not tall, can finish the spare parts with finite breed to machine only. 3 flexible production system (FMS) is flexible production system (the treatment system that FMS) is a kind of when expand on the foundation of FMC and form efficient, high accuracy, Gao Rou sex. Does the United States make engineer association be FMS definition: ? Lou calamity garden illuminate does eyebrow of the low A Chinese-style unlined garment that show scabbard attack does Lou of Qian ⑷ need Huo of part of the day of graph of さ ピ washs ⒃ common pa to vase showing languid fars away suddenly about gallop garden of Shao of of aim of extensive of bursa of horsefly of ば of discharge of pilfer of Huang of Kuo of the Jie that return ば illuminate low field? ? Lou calamity garden illuminate equipment of NC Machining of the low San that show cowardly, stock store motion unit and the automation that the computer controls the composition such as the system make a system, include many flexible production unit, can adjust quickly according to making the task or the change that produce an environment, apply to much breed, medium the production of small lot. Is FMS main by following do 3 parts comprise: ? Huo of Nai of of far of ⒆ of low field of は of commonplace of cloth of Tao provides dinner for low field ⒓ attacks place of? of Bin of H of low field of Pu of Qian Piao is shown. Of graph 2 FMS form (1) processes a system. Treatment system machines the composition of CNC machine tool of the spare parts by a certain number of stages normally. Treatment system can process all sorts of work automatically according to the instruction of all of computer science department, can change automatically workpiece and cutting tool. (2) content sheds a system. The content in FMS sheds system and traditional transfer matic or automation line to have very big difference, its whole workpiece carries systematic work state can undertake modulatory randomly, and install have store makings library is versed in each with adjusting on the difference of handling time. The memory that content sheds a system to include work, carry and carry wait for a few respects. (3) controls a system. Control system includes process control and process surveillance two stature systems, is its function: respectively? Small official of は of bits commonplace unplugs Huo provides dinner for small car mires exhausted of far Piao makes an appointment with bully know well well the information in MS of rancorring of painful of of fir of far of Feng of the that prick is undertaken handle and be controllinged by multistage computer. 4 last words by FMS stock more cutting tool, clamping apparatus and CNC Machining program, because this can accept the treatment of all sorts of different spare partses, solved much breed, medium the productivity in small lot production and flexible the contradiction between, be out of shape to expanding the production of the product and new product are developed particularly advantageous. Good because of controlling flexibility centrally, the workpiece in machining a process is carried and cutting tool changes etc implemented automation, interpose person of the person reduces lowermost rate, increased production successional with numerical control utilization rate of equipment and installations, so, production is periodic short, cost is low. Pass the data processing of the computer, use in machining a process detect automatically equipment, can discover machine tool precision, cutting tool wears away at any time the issue that reachs the respect such as treatment quality to appear, can take step in time, make machine quality to get assuring. Additional, because FMS has the characteristic with tall flexible, tall productivity and preparative short time, can make quick response to the change of the market, can keep lesser in goods and stock level.
