【正文】 After the research, the establishment of the related and standard norm. The main reason that analyzes to exist the abovementioned margin contain following few aspectses. the the characteristics understanding shortage of the industry progress huge, plexity and longterm to the domestic number。 mercialize, built up to control such as the number in , the aerospace number controls etc. to have the batch quantity production ability of number control the system production number controls a servo system and servo electrical engineerings of to produce factory and Pekings in the state electrical engineering factory, the first tool machine factory, south the first tool machine factory etc. some number controls the host production produce the factory basic became the our country of number control the industry base. up a number controls the research, development, basic troops of the management professional.Although obtained the substantial progress in the aspects of counting to control the technical research development and industries to turn, we also want to know awakely, the our country high level number controls the technical research development, is the technique level present condition and the realistic need of the our countries that turns the aspect in the industry to still have the bigger margin from see the development speed of the our country very quick lengthways, horizontal ratio( with abroad contrast) not only the technique level contain margin, in some aspects development speed also have the margin, the number of namely some high point control the technique level margin of the material contain the extension up to see from the nations, control the technique level and industries to turn the level estimate of to the our country number mostly and as follows. the technique level, fall behind 1015 years about with the foreign advanced level, the sharp technique aspect is then larger in the high . industry turns the level up, the market share is low, the species overlays the rate small, still have no to bee the scale production。At the aviation and the astronautics industry realms, zero partses that it process are the thin walls and thin much, just the degree is badly, the material is aluminum or the aluminum metal alloys, only under the condition that high slice to pare the speed and slice to pare the dint pimping, then can carry on process to these the large and whole aluminum metal alloy 坯 to anticipate the method for fish out recently to make the large spare parts of plane wing, fuselage of airplane...etc. to act for several spare partses to pass numerous rivet, bolts and other coupling methods to put together to pack, make the strength of the piece just the degree and credibilities get the all put forward the high speed, high and high and gentle request towards processing the material. See from the EMO2001 exhibition meeting circumstance, the high speed process the center to enter and can amount to the 80 ms/ min for speed, even higher, the air freight go the speed and can amount to the 100 ms/ min or many automobile factories in the world, include the . pany of Shanghai of the our country, have already at a high speed adopt to process the production line part that center constitute to act for to bine the tool tool machine of HyperMach of the American pany of CINCINNATI enter is biggest for speed to amount to the 60 ms/ min, fast is a 100 ms/ min, the acceleration amounts to the 2 gs, the principal axis turn soon and already 60000 rses/ one thin wall airplane spare parts, use the 30 mins only, but the spare parts of the same processes to need the 3 hs in the general highspeed miller, processing to need the 8 hs in the mon miller。ted lie in to produce what, but lie in how production, use what production.Make the technique and materials are the most basic production of mankind39。中國機床工具工業(yè)協(xié)會不良機制造成人才流失，又制約了技術及技術路線創(chuàng)新、產(chǎn)品創(chuàng)新，且制約了規(guī)劃的有效實施，往往規(guī)劃理想，實施困難?？v觀我國數(shù)控技術近50年的發(fā)展歷程，特別是經(jīng)過4個5年計劃的攻關，總體來看取得了以下成績。在此階段，由于改革開放和國家的重視，以及研究開發(fā)環(huán)境和國際環(huán)境的改善，我國數(shù)控技術的研究、開發(fā)以及在產(chǎn)品的國產(chǎn)化方面都取得了長足的進步。2美國的STEP而在新標準下，NC程序可以分散在互聯(lián)網(wǎng)上，這正是數(shù)控技術開放式、網(wǎng)絡化發(fā)展的方向。數(shù)控技術誕生后的50年間的信息交換都是基于ISO6983標準，即采用G，M代碼描述如何（how）加工，其本質(zhì)特征是面向加工過程，顯然，他已越來越不能滿足現(xiàn)代數(shù)控技術高速發(fā)展的需要。重視新技術標準、規(guī)范的建立網(wǎng)絡化數(shù)控裝備是近兩年國際著名機床博覽會的一個新亮點。System)等。AutomationGeneration21世紀的數(shù)控裝備將是具有一定智能化的系統(tǒng)，智能化的內(nèi)容包括在數(shù)控系統(tǒng)中的各個方面：為追求加工效率和加工質(zhì)量方面的智能化，如加工過程的自適應控制，工藝參數(shù)自動生成；為提高驅動性能及使用連接方便的智能化，如前饋控制、電機參數(shù)的自適應運算、自動識別負載自動選定模型、自整定等；簡化編程、簡化操作方面的智能化，如智能化的自動編程、智能化的人機界面等；還有智能診斷、智能監(jiān)控方面的內(nèi)容、方便系統(tǒng)的診斷及維修等。因此促進了復合主軸頭類型5軸聯(lián)動機床和復合加工機床（含5面加工機床）的發(fā)展。采用5軸聯(lián)動對三維曲面零件的加工，可用刀具最佳幾何形狀進行切削，不僅光潔度高，而且效率也大幅度提高。附錄1 (中文譯文)數(shù)控技術和裝備發(fā)展趨勢及對策摘要：簡要介紹了當今世界數(shù)控技術及裝備發(fā)展的趨勢及我國數(shù)控裝備技術發(fā)展和產(chǎn)業(yè)化的現(xiàn)狀，在此基礎上討論了在我國加入WTO和對外開放進一步深化的新環(huán)境下，發(fā)展我國數(shù)控技術及裝備、提高我國制造業(yè)信息化水平和國際競爭能力的重要性，并從戰(zhàn)略和策略兩個層面提出了發(fā)展我國數(shù)控技術及裝備的幾點看法。高速、高精加工技術及裝備的新趨勢在可靠性方面，國外數(shù)控裝置的MTBF值已達6一般認為，1臺5軸聯(lián)動機床的效率可以等于2臺3軸聯(lián)動機床，特別是使用立方氮化硼等超硬材料銑刀進行高速銑削淬硬鋼零件時，5軸聯(lián)動加工可比3軸聯(lián)動加工發(fā)揮更高的效益。WorkStation/MachineSystems)、日本的OSEC(Open數(shù)控系統(tǒng)開放化已經(jīng)成為數(shù)控系統(tǒng)的未來之路。數(shù)控裝備的網(wǎng)絡化將極大地滿足生產(chǎn)線、制造系統(tǒng)、制造企業(yè)對信息集成的需求，也是實現(xiàn)新的制造模式如敏捷制造、虛擬企業(yè)、全球制造的基礎單元。關于數(shù)控系統(tǒng)設計開發(fā)規(guī)范為此，國際上正在研究和制定一種新的CNC系統(tǒng)標準ISO14649（STEP－NC)，其目的是提供一種不依賴于具體系統(tǒng)的中性機制，能夠描述產(chǎn)品整個生命周期內(nèi)的統(tǒng)一數(shù)據(jù)模型，從而實現(xiàn)整個制造過程，乃至各個工業(yè)領域產(chǎn)品信息的標準化。其次，STEPNC數(shù)控系統(tǒng)還可大大減少加工圖紙（約75％）、加工程序編制時間（約35％）和加工時間（約50％）。Tools公司是全球范圍內(nèi)制造業(yè)數(shù)據(jù)交換軟件的開發(fā)者，他已經(jīng)開發(fā)了用作數(shù)控機床加工信息交換的超級模型(Super對我國數(shù)控技術及其產(chǎn)業(yè)發(fā)展的基本估計第三階段是在國家的“八五”的后期和“九五”期間，即實施產(chǎn)業(yè)化的研究，進入市場競爭階段。分析存在上述差距的主要原因有以下幾個方面。戰(zhàn)略考慮發(fā)展策略在高精尖裝備研發(fā)方面，要強調(diào)產(chǎn)、學、研以及最終用戶的緊密結合，以“做得出、用得上、賣得掉”為目標，按國家意志實施攻關，以解決國家之急需。［J］.世界制造技術與裝備市場，2001(3)：1820.［2］s production data, but the number control the technique and is an advanced manufacturing technique and material to is most the technique of the core the international munity manufacturing industry adopts the number to control the technique extensively, making the ability and levels with the exaltation, the exaltation changes the orientation ability and the petition abilities of the market to the dynamic state addition in the world the flourishing nation of each industry return to
