【正文】 ry production existence question. At present many countries conduct the research to the open style numerical control system, like US39。s OSACA (Open System Architecture for Control within Automation Systems), Japan39。s ONC (Open Numerical Control System) and so on. The numerical control system will open already bees the numerical control system road of the future. The socalled open style numerical control system is the numerical control system development may in the unified movement platform, face the engine bed factory and the enduser, through the change, the increase or the tailor structure object (numerical control function), forms the seriation, and may conveniently integrates user39。 German Simens (Siemens) the pany displays Open Manufacturing Environment (opening manufacture environment, is called OME) and so on, had reflected the numerical control engine bed processing the tendency which develops to the work direction takes the new technical standard, the standard establishment about numerical control system design development gauge As noted previously, there are better monability , flexibility , adaptability , expanding in the open numerical control system, countries such as . , European Community and Japan ,etc. implement the strategic development plan one after another , carry on research and formulation of the systematic norm of structural numerical control of the open system (OMAC , OSACA , OSEC ), 3 of world heavy economy carry on the same science plan and standardize formulation nearly in a short time most, have indicated a new arrival of period of change of the technology of numerical control. Our country started research and formulation which standardized the frame of ONC numerical control system of China too in 2021. About the numerical control standard The numerical control standard is a kind of trend of informationbased development of manufacturing industry. Numerical control technology information exchange of 50 year born , to based on ISO6983 standard, adopt G , M code describes how processes, its essential characteristic faces the processing course, obviously, he can39。s basic team . Though has made considerable progress in research and development and industrialization of the technology of numerical control, but we will realize soberly, the research and development of the technology of advanced numerical control of our country, there is greater disparity between current situation and current demand of our country of engineering level especially in industrialization. Though very fast from longitudinal development to watch our country, horizontal until (contrast with foreign countries ) , the engineering level has disparity, there is disparity too in development speed in some aspects, . the disparity of engineering level between some highgrade , precision and advanced numerical control equipment has the tendency to expand . Watch from world , estimate roughly as follows about the numerical control engineering level of our country and industrialization level. the engineering level, in probably backward 10 1 years with the advanced level in foreign countries, it is bigger in highquality precision and sophisticated technology. the industrialization level, the market share is low, the variety coverage rate is low, have not formed the largescale production yet。 Not setting up one39。 The research , formulation that relevant standards are normal lags behind. It is analyzed that the main reason for having disparity described above has the following several respect. the respect. Know to domestic numerical control industry process arduousness , plexity and longterm characteristic insufficiently。39。 Secondly seen from security of national defence, the western developed country has classified all the highgrade , precision and advanced numerical control products as the strategic materials of the country, realize embargo and restriction to our country, Toshiba incident and Cox Report is the best illustration. Development tactics Proceed from the angles of the fundamental realities of the country of our country, regard the strategic demand of the country and market demand of the national economy as the direction, regard improving our country and making the prehensive petitive power of equipping industry and industrialization level as the goal, use the systematic method , be able to choose the support technology that the initial our country makes the key technology upgraded in development of equipping industry and supports the development of industrialization in 21st century of leading factor, the ability to supply the necessary technology realizes making the jump type development of the equipping industry as the content of research and development. Emphasize market demand is a direction, take terminal products of numerical control as the core , with the plete machine (Such as the numerical control lathe having a large capacity and a wide range, milling machine , high speed high precise highperformance numerical control lathe , model digitized machinery , key industry key equipment ,etc. ) drive numerical control development of industry. Solve the numerical control system and relevant functions part especially The dependability in (digitized servo system and electrical machinery , electric main shaft system of high speed and new attachment that equip ,etc. ) and production scale question. There are no products without high dependability of scale 。馬克思曾經(jīng)說過 “ 各種經(jīng)濟(jì)時(shí)代的區(qū)別，不在于生產(chǎn)什么，而在于怎樣生產(chǎn)，用什么勞動(dòng)資料生產(chǎn) ” ?？傊罅Πl(fā)展以數(shù)控技術(shù)為核心的先進(jìn)制造技術(shù)已成為世界各發(fā)達(dá)國(guó)家加速經(jīng)濟(jì)發(fā)展、提高綜合國(guó)力和國(guó)家地位的重要途徑。 1． 1 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。近來采用大型整體鋁合金坯料 “掏空 ”的方法來制造機(jī)翼、機(jī)身等大型零件來替代多個(gè)零件通過眾多的鉚釘、螺釘和其他聯(lián)結(jié)方式拼裝，使構(gòu)件的強(qiáng)度、剛度和可靠性得 到提高。美國(guó) CINCINNATI 公司的 HyperMach 機(jī)床進(jìn)給速度最大達(dá) 60m/min，快速為 100m/min，加速度達(dá) 2g，主軸轉(zhuǎn)速已達(dá) 60000r/min。 為了實(shí)現(xiàn)高速、高精加工，與之配套的功能部件如電主軸、直線電機(jī)得到了快速的發(fā)展，應(yīng)用領(lǐng)域進(jìn)一步擴(kuò)大。 當(dāng)前由于電主軸的出現(xiàn)，使得
