【正文】 s accession to the WTO and opening to the outside world on this basis, develop technology of numerical control of our country and the importance of the informationbased level of manufacturing industry of our country and international petitiveness equips , improves, and has put forward technology of numerical control of our country and some views equipped of developing from two aspects of strategy and tactics. The engineering level of equipment industry and modernized intensity are determining the level of the whole national economy and modernized intensity , numerical control technology and equip , develop new developing new hightech industry and most advanced industry To can make technology and basic equipment most (national defense industry industries , such as information technology and their industry , biotechnology , industry , aviation , spaceflight ,etc. ). Marx has ever said the differences of different economic times, do not lie in what is produced, lie in how produce, with what means of labor produce . Manufacturing technology and equipping the most basic means of production that are that the mankind produced the activity, and numerical control technology to equip most central technology. Nowadays the manufacturing industry all around the world adopts the technology of numerical control extensively。 (5)Transducer technology。 The paces and acceleration of main shaft of dual main shaft lathes of Germany DMG Company reach 12* separately! 000r/mm and 1g. In machining accuracy, in the past 10 years, ordinary progression has accused of the machining accuracy of the lathe to already improve from 10μm to 5μm, accurate grades of machining center from 3 5μm, raise to 1 , and ultraprecision machining accuracy begin , enter getting nanometer already. In machining accuracy, the past 10 years, ordinary progression accuse of machining accuracy of lathe raise to 5μm , from 3 5μm accurate grades of machining center from 10μm already, improve to 1 , and the ultraprecision machining accuracy has already begun to enter nanometer ( )ly. In dependability, MTBF value of the foreign numerical co ntrol device has already reached above 6 000h, MTBF value of the servo system reaches above 30000h, demonstrate very high dependability . For realize at a high speed , high finish machining, related to it function part if electric main shaft , straight line electrical machinery get fast development, the application is further expanded . 5 axles link and process and pound and process the lathe to develop fast Adopt 5 axle link , to threedimensional curved surface processing of part , can cut with the best geometirc form of the cutter, not only highly polished, but also efficiency is improved by a large margin . It is generally acknowledged , a 5 axle gear beds of efficiency can equal 2 3 axle gear beds , use cubic nitrogen boron wait ultra hard material milling cutter go on at a high speed milling , sharpening , quenching hard steel at the part, 5 axle link , process constant 3 axle link , process , give play to high benefit. But go over because 5 axles link the numerical control system , plicated reason of host puter structure, price its link numerical control to be lathe several times higher than 3 axle, in addition programming technological difficulty relatively heavy , have restricted 5 axle gear beds of development. At present because of electric appearance of main shaft, make , realize 5 axle pound main shaft hair structure processed to link greatly simplify, it make difficulty and cost reduce by a large margin , numerical control price disparity of systems shrink. So promote pound main shaft head type 5 axle gear bed and pound development to process lathe (process the lathe including 5 ). At EMO2021 exhibition, new Japanese 5 of worker machine process lathe adopt pound main shaft hair, can realize 4 processing and arbitrary processing of angle of vertical plane, make 5 process and 5 axles are processed and can be realized at the same lathe, can also realize the inclined plane and pour the processing of the hole of awls . Company , DMG of Germany , exhibit DMUVoution series machining center , can put , insert , down 5 process and 5 axes link and process in one, can be controlled by CNC system or CAD/CAM controls directly or indirectly. intellectualizations, open style, the work turns into for the contemporary numerical control system development mainly hastens The 21st century numerical control equipments will be has certain intellectualized the system, the intellectualized content including in numerical control system each aspect: In order to pursue the processing efficiency and the processing quality aspect intellectualization, like processing process adaptive control, craft parameter automatic production。39。39。39。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。制造技術(shù)和裝 備就是人類(lèi)生產(chǎn)活動(dòng)的最基本的生產(chǎn)資料，而數(shù)控技術(shù)又是當(dāng)今先進(jìn)制造技術(shù)和裝備最核心的技術(shù)。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。加工一薄壁飛機(jī)零件，只用 30min，而同樣的零件在一般高速銑床加工需 3h，在普通銑床加工需 8h；德國(guó) DMG 公司的雙主軸車(chē)床的主軸速度及加速度分別達(dá) 12*!000r/mm 和1g。但過(guò)去因 5 軸聯(lián)動(dòng)數(shù)控系統(tǒng)、主機(jī)結(jié)構(gòu)復(fù)雜等原因，其價(jià)格要比 3 軸聯(lián)動(dòng)數(shù)控機(jī)床高出數(shù)倍，加之編程技術(shù)難度較大，制約了 5 軸聯(lián)動(dòng)機(jī)床的發(fā)展。目前世界上許多汽車(chē)廠，包括我國(guó)的上海通用汽車(chē)公司，已經(jīng)采用以高速加工中心組成的生產(chǎn)線部分替代組合機(jī)床。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［ 1～ 4］。 裝備工業(yè)的技術(shù)水平和現(xiàn)代化程度決定著整個(gè)國(guó)民經(jīng)濟(jì)的水平和現(xiàn)代化程度，數(shù)控技術(shù)及裝備是發(fā)展新興高新技術(shù)產(chǎn)業(yè)和尖端工業(yè)（如信息技術(shù)及其產(chǎn)業(yè)、生物技術(shù)及其產(chǎn)業(yè)、航空、航天等國(guó)防工業(yè)產(chǎn)業(yè)）的使能技術(shù)和最基本的裝備。 Set up intact related system , plete training , service work ,etc. of high quality support the system. .
