【正文】 h 80m/min is even high , air transport petent 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 highspeed machining center makes up. HyperMach lathe of . 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。 (4)Servo drive technology。畢業(yè)設(shè)計(jì)外文文獻(xiàn)翻譯 1 Numerical control technology and equipping development trend and countermeasure Zhao Changming Liu Wangju (CNC Machining Process and equipment, 2020,China) Abstract:Equip the engineering level, level of determining the whole national economy of the modernized degree and modernized degree of industry, numerical control technology is it develop new developing new hightech industry and most advanced industry to equip (such as information technology and his industry, biotechnology and his industry, aviation, spaceflight, etc. national defense industry) last technology and getting more basic most equipment. Numerical control technology is the technology controlled to mechanical movement and working course with digital information, integrated products of electromechanics that the numerical control equipment is the new technology represented by numerical control technology forms to the manufacture industry of the tradition and infiltration of the new developing manufacturing industry, Keywords: Numerical ControlTechnology, Equipment, industry Equip the engineering level, level of determining the whole national economy of the modernized degree and modernized degree of industry, numerical control technology is it develop new developing new hightech industry and most advanced industry to equip (such as information technology and his industry, biotechnology and his industry, aviation, spaceflight, etc. national defense industry) last technology and getting more basic most equipment. Marx has ever said the differences of different economic times, do not lie in what is produced, and lie in how to produce, produce with some means of labor . Manufacturing technology and equipping the most basic means of production that are that the mankind produced the activity, and numerical control technology is nowadays advanced manufacturing technology and equips the most central technology. Nowadays the manufacturing industry all around the world adopts numerical control technology extensively, 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 畢業(yè)設(shè)計(jì)外文文獻(xiàn)翻譯 2 numerical control equipment of numerical control as the strategic materials of the country, not merely take the great measure to develop one39。 (3)Automatic control technology。s 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 equipping the development trend to see, there is the following several respect [1 ] in its main research focus. 1 A highspeed, high finish machining technology and new trend equipped The efficiency, quality are subjavanufacturing technology. Highspeed, high 畢業(yè)設(shè)計(jì)外文文獻(xiàn)翻譯 3 finish machining technology can raise the efficiency greatly , improve the quality and grade of the products, shorten production cycle and improve the market petitive 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. I n 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。 The ones that simplified programming , simplified operating aspect are intelligent, for instance intelligent automatic programming , intelligent manmachine interface ,etc.。t meet highspeed development of modern numerical control technology39。 Appearance quality is relatively poor。 It is not strong that the technological application of numerical control expands dynamics。 It is not enough to analyse to the technological application level and ability of numerical control of our country. （ 2） 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。s question , at first seen from social safety, because manufacturing industry whether our country obtain employment most populous trade, the development of manufacturing industry not only can improve the people39。 Certainly, it is difficult to have day holding up one39。當(dāng)今世界各國制造業(yè)廣泛采用數(shù)控技術(shù)，以提高制造能力和水平，提高對動態(tài)多變市場的適應(yīng)能力和競爭能力。 1. 數(shù)控技術(shù)的發(fā)展趨勢 數(shù)控技術(shù)的應(yīng)用不但給傳統(tǒng)制造業(yè)帶來了革命性的變化，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，他對國計(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。為此日本先端技術(shù)研究會將其列為 5 大現(xiàn)代制造技術(shù)之一，國際生產(chǎn)工程學(xué)會（ CIRP）將其確 定為 21 世紀(jì)的中心研究方向之一。從 EMO2020 展會情況 來看，高速加工中心進(jìn)給速度可達(dá) 80m/min，甚至更高，空運(yùn)行速度可達(dá) 100m/min 左右。 在加工精度方面，近 10 年來，普通級數(shù)控機(jī)床的加工精度已由 10μm提高到 5μm，精密級加工中心則從 3～ 5μm，提高到 1～ ，并且超精密加工精度已開始進(jìn)入納米級 ()。一
