(2)Information processing , processing , transmission technology; (3)Automatic control technology; (4)Servo drive technology; (5)Technology of the sensor ; (6)Software engineering ,etc. Development trend of a numerical control technology The application of numerical control technology has not only brought the revolutionary change to manufacturing industry of the tradition, make the manufacturing industry become the industrialized symbol , and with the constant development of numerical control technology and enlargement of the application, the development of some important trades (IT , automobile , light industry , medical treatment ,etc. ) to the national economy and the peoples livelihood of his plays a more and more important role, because the digitization that these trades needed to equip has already been the main trend of modern development. Numerical control technology in the world at present and equiping the development trend to see, there is the following several respect 1- in its main research focus . 1.A high-speed , high finish machining technology and new trend equipped The efficiency , quality are subjavanufacturing technology. High-speed , high finish machining technology can raise the efficiency greatly , improve the quality and grade of the products, shorten production cycle and improve the market competitive power. Japan carries the technological research association first to classify it as one of the 5 great modern manufacturing technologies for this, learn (CIRP ) to confirm it as the centre in the 21st century and study one of the directions in international production engineering. In the field of car industry, produce one second when beat such as production of 300,000 / vehicle per year, and many variety process it is car that equip key problem that must be solved one of; In the fields of aviation and aerospace industry, spare parts of its processing are mostly the thin wall and thin muscle, rigidity is very bad, the material is aluminium or aluminium alloy, only in a situation that cut the speed and cut strength very small high, could process these muscles , walls . Adopt large-scale whole aluminium alloy method that blank pay empty make the wing recently, such large-scale parts as the fuselage ,etc. come to substitute a lot of parts to assemble through numerous rivet , screw and other connection way, make the intensity , rigidity and dependability of the component improved. All these, to processing and equiping the demand which has proposed high-speed , high precise and high flexibility. According to EMO2001 exhibition situation, high-speed machining center is it give speed can reach 80m/min is even high , air transport competent speed can up to 100m/min to be about to enter. A lot of automobile factories in the world at present, including Shanghai General Motors Corporation of our country, have already adopted and substituted and made the lathe up with the production line part that the high-speed machining center makes up . HyperMach lathe of U.S.A. CINCINNATI Company enters to nearly biggest 60m/min of speed, it is 100m/min to be fast, the acceleration reaches 2g, the rotational speed of the main shaft has already reached 60 000r/min. Processing a thin wall of plane parts, spend 30min only, and same part general at a high speed milling machine process and take 3h, the ordinary milling machine is being processed to need 8h; The speed and acceleration of main shaft of dual main shaft lathes of Germany DMG Company are up to 12* separately! 000r/mm and 1g. In machining accuracy, the past 10 years, ordinary progression accuse of machining accuracy of lathe bring 5m up to from 10m already, accurate grades of machining center from 3- 5m, rise to 1- 1.5m, and ultraprecision machining accuracy is it enter nanometer grade to begin already (0.01m). In dependability, MTBF value of the foreign numerical control device has already reached above 6 000h, MTBF value of the servo system reaches above 30000h, demonstrate very high dependability . In order to realize high-speed , high finish machining, if the part of function related to it is electric main shaft , straight line electrical machinery get fast development, the application is expanded further. 1.2 Link and process and compound to process the fast development of the lathe in 5 axes Adopt 5 axles to link the processing of the three-dimensional curved surface part, can cut with the best geometry form of the cutter , not only highly polished, but also efficiency improves by a large margin . It is generally acknowledged , the efficiency of an 5 axle gear beds can equal 2 3 axle gear beds , is it wait for to use the cubic nitrogen boron the milling cutter of ultra hard material is milled and pared at a high speed while quenching the hard steel part, 5 axles link and process 3 constant axles to link and process and give play to higher benefit. Because such reasons as complicated that 5 axles link the numerical control system , host computer structure that but go over, it is several times higher that its price links the numerical control lathe than 3 axles , in addition the technological degree of difficulty of programming is relatively great, have restricted the development of 5 axle gear beds. At present because of electric appearance of main shaft, is it realize 5 axle complex main shaft hair structure processed to link greatly simplify to make, it makes degree of difficulty and reducing by a large margin of the cost, the price disparity of the numerical control system shrinks . So promoted 5 axle gear beds of head 無(wú)效 of complex main shaft and compound to process the development of the lathe (process the lathe including 5 ). At EMO2001 exhibition, new Japanese 5 of worker machine process lathe adopt complex main shaft hair, can realize the processing of 4 vertical planes and processing of the wanton angle , make 5 times process and 5 axles are processed and can be realized on the same lathe, can also realize the inclined plane and pour the processing of the hole of awls . Germany DMG Company exhibits the DMUVoution series machining center, but put and insert and put processing and 5 axles 5 times to link and process in once, can be controlled by CNC system or CAD/CAM is controlled directly or indirectly. 1.3 Become the main trend of systematic development of contemporary numerical control intelligently , openly , networkedlily The numerical control equipment in the 21st century will be sure the intelligent system, the intelligent content includes all respects in the numerical control system: It is intelligent in order to pursue the efficiency of processing and process quality, control such as the self-adaptation of the processing course, the craft parameter is produced automatically; Join the convenient one in order to improve the performance of urging and use intelligently, if feedforward control , adaptive operation , electrical machinery of parameter , discern load select models , since exactly makes etc. automatically automatically; The ones that simplified programming , simplified operating aspect are intelligent, for instance intelligent automatic programming , intelligent man-machine interface ,etc.; There are content of intelligence diagnose , intelligent monitoring , diagnosis convenient to be systematic and maintaining ,etc. Produce the existing problem for the industrialization of solving the traditional numerical control system sealing and numerical control application software. A lot of countries carry on research to the open numerical control system at present, such as NGC of U.S.A. (The Next Generation Work-Station/Machine Control), OSACA of European Community (Open System Architecture for Control within Automation Systems), OSEC (Open System Environment for Controller ) of Japan, ONC (Open Numerical Control System ) of China ,etc. The numerical control system melts to become the future way of the numerical control system open. The so-called open numerical control system is the development of the numerical control system can be on unified operation platform, face the lathe producer and end user, through changing, increasing or cutting out the structure target(numerical control function), form the seriation, and can use users specially conveniently and the technical know-how is integrated in the control system, realize the open numerical control system of different variety , different grade fast, form leading brand products with distinct distinction. System structure norm of the open numerical control system at present, communication norm , disposing norm , operation platform , numerical control systematic function storehouse and numerical control systematic function software developing 包含ument ,etc. are the core of present research. The networked numerical control equipment is a new light spot of the fair of the internationally famous lathe in the past two years. Meeting production line , manufacture system , demand for the information integration of manufacturing company networkedly greatly of numerical control equipment, realize new manufacture mode such as quick make , fictitious enterprise , basic Entrance that the whole world make too. Some domestic and international famous numerical control lathes and systematic manufacturing companies of numerical control have all introduced relevant new concepts and proto無(wú)效s of a machine in the past two years, if in EMO2001 exhibition, CyberProduction Center that the company exhibits of mountain rugged campstool gram in Japan (Mazak ) (intellectual central production control unit, abbreviated as CPC); The lathe company of Japanese big Wei (Okuma ) exhibits IT plaza (the information technology square , is abbreviated as IT square ); Open Manufacturing Environment that the company exhibits of German Siemens (Siemens ) (open the manufacturing environment, abbreviated as OME),etc., have reflected numerical control machine tooling to the development trend of networked direction. 2 pairs of basic estimations of technology and industry development of numerical control of our country The technology of numerical control of our country started in 1958, the development course in the past 50 years can roughly be divided into 3 stages: The first stage is from 1958 to 1979, namely closed developing stage. In this stages, because technology of foreign countries blockade and basic restriction of terms of our country, the development of numerical control technology is comparatively slow. During Sixth Five-Year Plan Period , the Seventh Five-Year Plan Period of the country in second stage and earlier stage in the Eighth Five-Year Plan Period , namely introduce technology, digest and assimilate, the stage of establishing the system of production domesticization arisesing tentatively. At this stage , because of reform and opening-up and national attention , and study the improvement of the development environment and international environment, research , development and all making considerable progress in production domesticization of the products of the technology of numerical control of our country. The third stage is and during the Ninth Five-Year Plan Period on the later stage in the Eighth Five-Year Plan Period of the country, namely implement the research of industrialization, enter market competition stage. At this stage , made substantive progress in industrialization of the domestic numerical control equipment of our country. In latter stage for the Ninth Five-Year Plan , the domestic occupation rate of market of the domestic numerical control lathe is up to 50%, it is up to 10% too to mix the domestic numerical control system (popular ). Make a general survey of the development course in the past 50 years of technology of numerical control of our country, especially through tackling key problems of 4 Five-Year Plans, all in all has made following achievements. a.Have establish the foundation of the technical development of numerical control, has mastered modern numerical control technology basically. Our country has already, the numerical control host computer , basic technology of special plane and fittings grasped and driven from the numerical control system and servoly basically now, among them most technology have already possessed and commercialized the foundation developed , some technology has already, industrialization commercialized. b.Have formed the industrial base of numerical control tentatively. In tackling key problems the foundation that the achievement and some technology commercialize , set up the systematic factories of numerical control with production capacity in batches such as numerical control in Central China , numerical control of the spaceflight etc. Electrical machinery plant of Lanzhou, such factory and the first machine tool plant of Beijing , the first machine tool plant of Jinan ,etc. several numerical control host computer factories of a batch of servo systems and servo electrical machineries as the numerical control in Central China,etc. These factories have formed the numerical control industrial base of our country basically. c.Have set up a numerical control research, development , managerial talents basic team . Though has made considerable progress in research and development and industrialization of numerical control technology, but we will realize soberly, the research and development of the technology of advanced numerical control of our country, especially there is greater disparity in current situation and current demand of our country of engineering level in industrialization. Though very fast from watching the development of our country vertically, have disparity horizontally more than (compare foreign countries with ) not merely engineering level, there is disparity too in development speed in some aspects, namely the engineering level disparity between some high-grade , precision and advanced numerical control equipment has the tendency to expand . Watch from world , estimate roughly as follows about the engineering level of numerical control of our country and industrialization level. a.On the engineering level, in probably backward 10- 1 years with the advanced level in foreign countries, it is bigger in high-quality precision and sophisticated technology. b.On the industrialization level, the occupation rate of market is low, the variety coverage rate is little, have not formed the large-scale production yet; The specialized level of production of function part and ability of forming a complete set are relatively low; Appearance quality is relatively poor; Dependability is not high, the commercialized degree is insufficient; Ones own brand effect that the domestic numerical control system has not been set up yet, users have insufficient confidence. c.On the ability of sustainable development, research and development of numerical control technology , project ability are relatively weak to the competition; It is not strong that the technological application of numerical control expands dynamics; Research , formulation that relevant standards are normal lag behind. It is analysed that the main reason for having above-mentioned disparity has the following several respect. a.Realize the respect. Know to industrys process arduousness , complexity and long-term characteristic of domestic numerical control insufficiently; It is difficult to underestimate to add strangling , system ,etc. to the unstandard , foreign blockade of the market; It is not enough to analyse to the technological application level and ability of numerical control of our country. b.System. Pay close attention to numerical control industrialization many in the issue , consider numerical control industrialization little in the issue synthetically in terms of the systematic one , industry chain in terms of technology; Have not set up related system , perfect training , service network of intact high quality ,etc. and supported the system. c.Mechanism. It causes the brain drain, restraining technology and technological route from innovating again , products innovation that the bad machine is made, and has restricted the effective implementation of planning , has often planned the ideal , implement the difficulty. d.Technology. The autonomous innovation in technology of enterprises is indifferent, the project of key technology is indifferent. The standard of the lathe lags behind, the level is relatively low, it is not enough for new standard of the numerical control system to study.中文譯文數(shù)控技術(shù)和裝備發(fā)展趨勢(shì)及對(duì)策 數(shù)控技術(shù)是用數(shù)字信息對(duì)機(jī)械運(yùn)動(dòng)和工作過(guò)程進(jìn)行控制的技術(shù)，數(shù)控裝備是以數(shù)控技術(shù)為代表的新技術(shù)對(duì)傳統(tǒng)制造產(chǎn)業(yè)和新興制造業(yè)的滲透形成的機(jī)電一體化產(chǎn)品，即所謂的數(shù)字化裝備，其技術(shù)范圍覆蓋很多領(lǐng)域：(1)機(jī)械制造技術(shù)；(2)信息處理、加工、傳輸技術(shù)；(3)自動(dòng)控制技術(shù)；(4)伺服驅(qū)動(dòng)技術(shù)；(5)傳感器技術(shù)；(6)軟件技術(shù)等。1 數(shù)控技術(shù)的發(fā)展趨勢(shì) 數(shù)控技術(shù)的應(yīng)用不但給傳統(tǒng)制造業(yè)帶來(lái)了革命性的變化，使制造業(yè)成為工業(yè)化的象征，而且隨著數(shù)控技術(shù)的不斷發(fā)展和應(yīng)用領(lǐng)域的擴(kuò)大，他對(duì)國(guó)計(jì)民生的一些重要行業(yè)（IT、汽車、輕工、醫(yī)療等）的發(fā)展起著越來(lái)越重要的作用，因?yàn)檫@些行業(yè)所需裝備的數(shù)字化已是現(xiàn)代發(fā)展的大趨勢(shì)。從目前世界上數(shù)控技術(shù)及其裝備發(fā)展的趨勢(shì)來(lái)看，其主要研究熱點(diǎn)有以下幾個(gè)方面14。11 高速、高精加工技術(shù)及裝備的新趨勢(shì) 效率、質(zhì)量是先進(jìn)制造技術(shù)的主體。高速、高精加工技術(shù)可極大地提高效率，提高產(chǎn)品的質(zhì)量和檔次，縮短生產(chǎn)周期和提高市場(chǎng)競(jìng)爭(zhēng)能力。為此日本先端技術(shù)研究會(huì)將其列為5大現(xiàn)代制造技術(shù)之一，國(guó)際生產(chǎn)工程學(xué)會(huì)（CIRP）將其確定為21世紀(jì)的中心研究方向之一。 在轎車工
