【正文】 gress in production domesticization of the products of the technology of numerical control of our country. The third stage is that on the later stage in the Eighth FiveYear Plan Period of the country and during the Ninth FiveYear Plan Period , implement the research of industrialization , enter market petition stage. At this stage, made substantive progress in industrialization of the domestic numerical control equipment of our country. In the Ninth FiveYear Plan latter stage, domestic numerical control domestic market share of lathe reach 50% , mix domestic numerical control system (popular ) to up to 10%. Review the development course in the past 50 years of technology of numerical control of our country, especially pass the brainstorm of 4 FiveYear Plans, all in all has made following achievements. a. Have establish the foundation of the technical development of numerical control, has basically mastered the technology of modern numerical control. Our country know from numerical control system , servo urge , numerical control host puter , special plane and their basic of fittings basically already now, among them most technology have already possessed the foundation that is mercialized and developed , some technology has already, industrialization mercialized. formed the industrial base of numerical control tentatively. In tackling key problems the foundation that the achievement and some technology mercialize , set up the systematic factories of numerical control with production capacity of batch such as numerical control of Central China , spaceflight numerical control etc.. Electrical machinery plant of Lanzhou, a batch of servo systems and first machine tool plant , first machine tool plant of Jinan of servo electrical machinery factory and Beijing ,etc. several numerical control host puter factories such as the numerical control in Central China. These factories have basically formed the numerical control industrial base of our country. set up research of a numerical control, development , managerial talent39。s special application and the technical knack in the control system, the fast realization different variety, the different scale open style numerical control system, forms has the bright individuality famous brand goods. At present the open style numerical control system system structure standard, the correspondence standard, the disposition standard, the movement platform, the numerical control system function storehouse as well as t he numerical control system function software development kit and so on is the current research core The work numerical control equipment is a nearly two year international famous engine beds expositions new luminescent spot. The numerical control equipment work enormously will satisfy the production line, the manufacture system, the manufacture enterprise to the information integration demand, also will be realizes new manufacture pattern like agile manufacture, hypothesized enterprise, the global manufacture foundation unit. The domestic and foreign some famous numerical controls engine bed and the numerical control system manufacture pany has all promoted the related new concept and the prototype in the nearly two years, if unfolds in EMO2021, Japanese Shan Qima Mazak the pany displays CyberProduction Center (intelligence production control center, is called CPC)。s OSEC (Open System Environment for Controller), China39。S NGC (The Next Generation WorkStation/Machine Control), European Economic Community39。 In order to enhance the actuation performance and the use connection convenient intellectualization, like the feedforward control, the electrical machinery parameter autoadapted operation, the automatic diagnosis load automatic designation model, is automatic entire grades。39。 (6)Software engineering ,etc.. 1 Development trend of a numerical control technology The application of the technology of numerical control has not only brought the revolutionary change to traditional manufacturing industry, make the manufacturing industry bee the industrialized symbol , and with the constant development of the technology of numerical control and enlargement of application, the development of he some important trades (IT , car , light industry , medical treatment ,etc. ) to the national economy and the people39。 (2)Information processing , processing , transmission technology。 in order to improve manufacturing capacity and level, improve the adaptive capacity and petitive power to the changeable market of the trends. In addition every industrially developed country in the world also classifies the technology and numerical control equipment of numerical control as the strategic materials of the country, not merely take the great measure to develop one39。The development trend of the numerical control technology（數(shù)控技術的發(fā)展趨勢） —— 中英文對照 The development trend of the numerical control technology Summary : Have introduced numerical control technology and the development trend of the equipment and the current situations of the technical development of numerical control equipment and industrialization of our country of our times briefly , have discussed under the new environment further deepened in our country39。39。 (3)Automatic control technology。39。s spare parts are mostly the thin wall and thin muscle, rigidity very bad, material aluminum or aluminum alloy, in high to cut pace and cut strength very under the little situation only, could process these muscles, walls. Adopt largescale whole aluminium alloy blank method of pay empty make the wing recently, largescale parts such as the fuselage ,etc. e to substitute a lot of parts to assemble through numerous rivet , screw and other connection ways, make the intensity , rigidity and dependability of the ponent improved. All these requirement for processing and equipping
