Developed country of world each industry carries development numerical control technology, build industry of numerical control machine tool, make machining course of study cross new " modern " the history develops level, the structure that gives a countryman economy thereby brought tremendous change. One, machine tool of technical overview numerical control not only the main base that is Electromechanical industry equips, it is the main measure with the pillar industry modern production such as car, petrifaction, electron, numerical control machine tool also is a of revolution of the 3rd industry of world serious content. The production value of itself of industry of numerical control machine tool is far wait for an industry as car, chemical industry, but the benefit growth that the numerical control machine tool of tall efficiency gave manufacturing industry to bring tall fold and modern producer type, it is the huge source power that economy of stimulative country countryman expands. Especially numerical control technology is in of manufacturing industry expand the radiation effect that produces with outspread place is mixed affect effect enough is opposite the industrial structure of mechanical manufacturing industry, product structure, specialization the moving mechanism of means of division of labor, machining means and the manufacturing division of labor that run mode, society, enterprise change that brings profundity. The numerical control technology that uses extensively gets in numerical control machine tool, it is one kind uses the computer to all sorts of control in machining process information undertakes digitlizing operation, processing, the driving unit that tells exorbitant function has automation pilot to mechanical executive component new and high technology. Currently already many machining equipment used numerical control technology, among them the most typical and applied range is the widest is numerical control machine tool. As a result of the diversity of machining craft and the complexity that machine a spare parts, make difference of diversity of the norms of numerical control machine tool, breed, function great, control parameter is complex, debug an operation trival, when because this is in,theory of the technology of general purpose computer of will ceaseless flying development and its architecture, contemporary automata and technology of modern electric power electron use machine tool of Yuxin generation numerical control, ambitious attune makes its are had " open mode " with " intelligence is changed " characteristic. 1. "Open mode " the control system of machine tool of numerical control of requirement new generation is a kind of open mode, modular architecture, its characteristic is: In implementation the system is formed while element is modular, want to pass the standardization between these element, can combine the element that offers by different the buying party freely rise, can make whole system conveniently thereby. Specific as follows: - - - of the system making element should be modular, at the same time the interface between each module must be standardization; - - - construction of systematic software, hardware should be " transparent " , " can transplant " ; - - - the system should be had " upgrade continuously " ability. The rigid structure that is the same as machine tool of stylish generation numerical control also should be open mode, its characteristic should be: - - - the machine tool that uses composition of functional module component; - - - use " craft is engineered " , " treatment database " open to the user; - - - use " IT " what make the society resource is reasonable allocate build in mechanical manufacturing industry stage by stage those who perfect is fictitious change the advanced production system with network, make resource of mechanical manufacturing industry is used efficiently, achieve reduce cost, improve quality, shorten the purpose of production cycle. 2. Intelligence changes alleged intelligence to change numerical control system, it is to point to have personification intelligence feature, the knowledge that has imitate, outspread, patulous intelligence action in numerical control system treats an activity, if teach oneself be used to, suit oneself, organize oneself, find actor oneself, from aplomb, identify oneself, from program, self-educated answer, wait from breed. The physical quantity that system of intelligent numerical control carries pair of influences to machine precision and efficiency undertakes detecting, the in-house position that builds model, extraction to feel treatment system feature, automatically and external environment, make the intelligence that achieves optimal goal quickly decision-making, the craft parameter such as rotate speed of mobile to deepness of feed speed, cutting, coordinate, main shaft undertakes real time is controlled, make the treatment process of the machine tool is in groove. The function that place of system of current numerical control needs will be high performance not merely (high speed, high accuracy, high reliability) , and still include a lot of intelligence functions, if machine the perception of athletic program, inference, decision-making ability and treatment environment,ability, production network corresponds ability (include with the person alternant) , monitoring of database of intelligent process designing, intelligence, intelligence. The course carries out a proof, afore-mentioned " intelligence is changed " technology, apply at new generation to count those who charge a machine tool to adjust even in 21 centuries, use wait for each link with maintenance, make be participated in artificially simplify greatly, should apply " intelligence is changed " technology, undertake packing to man-machine interface, should make full use of of interface of natural language, window and simplification run artificially, make the adjustment of the machine tool, use tend with maintenance " goofy change " . 2, the current situation and trend of domestic and international development 1. Abroad develops a trend to review the development history of numerical control technology, the progress that sees numerical control technology not hard is to dog stage by stage of computer technology develop and develop ceaselessly, from 1956 up to now, experienced 4 following level roughly: 1956 - 1974, the times of special hardware NC; 1975 - 1989, times of special computerized numerical control, namely the times of microprocessor NC (µPC) ; 1990 - 1995, the CNC times of BASICPC; 1996 up to now, begin complete PC to open type intelligence to change numerical control new level. The NC unit of before 3 phase is consisting the following limitation: - - - cannot choose information freely from the website; - - - architecture is not open, user interface is not perfect, machinery plant home and user cannot own land basis needs to undertake cutting out to numerical control system, the technical know-how of user oneself cannot be blended in conveniently, innovation gives his famous brand product; - - - cannot use adequately already some current software resource; - - - cannot get freely external operating mode information; - - - architecture is various, go against batch production, rise dependability and reduce cost, weakened the market to supply ability and competitive capacity, limitted the development of numerical control technology at the same time. In recent years the United States, Europe in all the country such as body, Japan takes step in succession, throw many financial resources, combine each plant, multilateral even undertake cooperative, study the numerical control system of new generation, look from foregoing material, the numerical control technology of the world is lying to open type to complete PC turn of times of platform of architecture numerical control, the inevitable result of the development that this one turn got used to the technology such as technology of computer technology, IT, network just about. Because contemporary machining course of study is progressively,Xiang Rou sex is changed, compositive change, intelligence changes direction to develop, because technology of this new generation numerical control is indispensible,emphasize having the feature that open mode, intelligence changes. In last few years world developed country takes step in succession, force of dominant position of organization of devoted and much labor power, financial capacity undertakes new generation opens type architecture and the development of numerical control technology that have intelligence function and research, the NGC that includes the United States and OMAC plan, Europe in all the OSACA plan of body, OSEC plan of Japan. Structure of machinery of numerical control machine tool more incline to at " open mode " , to satisfy the diversification requirement of contemporary machining, the numerical control machine tool of new generation has the following characteristic: (1) machine tool structure undertakes by principle of modular, seriation design and make, so that shorten,offer commodity cycle, utmost satisfies the craft requirement of the user. (2) of the quality index of a lot of components as a result of numerical control machine tool rise ceaselessly, increase of breed norms gradually, Electromechanical unifinication content parameter of more rich, function with each passing day numerous and jumbled, because this is special all sorts of function parts that are form a complete set of numerical control machine tool are completely commercial already, created a condition to build the machine tool plant that has competitive capacity. (3) to be opened to the user, before the factory of numerical control machine tool of each developed country builds the product of wide-open type actively to make work, after service system. Build the spare parts lab of open mode, build operation of machine tool of self-help type numerical control, maintenance to groom center. (4) use technology of website sth resembling a net, socially all sorts of production resource undertake according to machining the task reasonable combination and call, it is the inevitable tendency that 21 centuries develop advanced production technology, world each country is undertaking the research of this respect works actively. (5) artificial intelligence turns the technical promotion application in numerical control technology. Be permeated ceaselessly in computer domain as artificial intelligence and develop, numerical control system changes development to intelligence. In the numerical control system in new generation and wait dress buy, because use " developmental computation " (EvolutionaryComputation) , "Ambiguous system " (FuzzySystem) and " nerve network " (NeuralNetwork) wait for the control mechanism with 3 new fields, function rises greatly. The numerical control system that this kind of high-powered intelligence changes not only have automatic process designing, before control of make a present of, get used to cutting oneself, craft parameter is generated oneself, the function such as compensation of athletic parameter trends, what have distinguishing feature more is the very friendly man-machine interface that appears considering the ingredient that the operation uses. The system of electric treatment numerical control that uses ambiguous control principle currently and have the machine tool of self-study be used to, high-powered numerical control that builds mathematical model, self-regulated to rectify parameter oneself to servo actuating device already had a product and have strong competitive capacity in the market. 2. Technology of our country numerical control develops the numerical control technology of the current situation and difference our country, be in " 85 " in tackling key problem, put forward at once to be a target with own copyright, it is development strategy of the foundation with platform, and tackling key problem in the process, aim at or adjust the development course that is a foundation with the PC to go up, formed two kinds of platform with this, development gave 4 basic systems, the I in its China with China I model it is the system of stand-alone numerical control that numerical control special pattern plate embeds current PC is formed, spaceflight I with Lan Tian I model it is the system of much chance numerical control that embeds the PC be formed in numerical control, form typical around station structure, domestic other unit also develops open type early or late architecture system. However overall and theory, still be in merely begin phase, although each systems develop to PC platform direction, but still put in a few problems in specific executive development. The biggest question is open sex namely environment of insufficient, development and supportive method are insufficient, the open rate that should have 2 times developing conveniently as the user is far still did not achieve, just have quite the development unit ability of technical force is used, and return as the degree that can popularize average user far insufficient. Use a PC to design numerical control system to make the key of CNC turns to software by hardware, eliminated hardware to go up for the numerical control development of our country " bottleneck " restrict, accelerate production possibly to give economic product thereby. And PC - NC makes after all CNC to open sex architecture strode one stride. Design in numerical control machine tool with in making, our country already began to use modular technology, process system of medium craft parameter, tool to numerical control cutting optimize, intelligent adaptive control has undertaken study, it considers to lay a foundation further to change pilot to intelligence, but afore-mentioned jobs are merely germinant, still need to be in " 15 " during undertake a series of development consider to work, dog technology of world numerical control, promote the development of industry of our country numerical control. 3, " 15 " target and main research content 1.
