【正文】 60。戰(zhàn)略考慮我國是制造大國,在世界產業(yè)轉移中要盡量接受前端而不是后端的轉移,即要掌握先進制造核心技術,否則在新一輪國際產業(yè)結構調整中,我國制造業(yè)將進一步“空芯”。我們以資源、環(huán)境、市場為代價,交換得到的可能僅僅是世界新經濟格局中的國際“加工中心”和“組裝中心”,而非掌握核心技術的制造中心的地位,這樣將會嚴重影響我國現(xiàn)代制造業(yè)的發(fā)展進程。我們應站在國家安全戰(zhàn)略的高度來重視數(shù)控技術和產業(yè)問題,首先從社會安全看,因為制造業(yè)是我國就業(yè)人口最多的行業(yè),制造業(yè)發(fā)展不僅可提高人民的生活水平,而且還可緩解我國就業(yè)的壓力,保障社會的穩(wěn)定;其次從國防安全看,西方發(fā)達國家把高精尖數(shù)控產品都列為國家的戰(zhàn)略物質,對我國實現(xiàn)禁運和限制,“東芝事件”和“考克斯報告”就是最好的例證。發(fā)展策略從我國基本國情的角度出發(fā),以國家的戰(zhàn)略需求和國民經濟的市場需求為導向,以提高我國制造裝備業(yè)綜合競爭能力和產業(yè)化水平為目標,用系統(tǒng)的方法,選擇能夠主導21世紀初期我國制造裝備業(yè)發(fā)展升級的關鍵技術以及支持產業(yè)化發(fā)展的支撐技術、配套技術作為研究開發(fā)的內容,實現(xiàn)制造裝備業(yè)的跨躍式發(fā)展。強調市場需求為導向,即以數(shù)控終端產品為主,以整機(如量大面廣的數(shù)控車床、銑床、高速高精高性能數(shù)控機床、典型數(shù)字化機械、重點行業(yè)關鍵設備等)帶動數(shù)控產業(yè)的發(fā)展。重點解決數(shù)控系統(tǒng)和相關功能部件(數(shù)字化伺服系統(tǒng)與電機、高速電主軸系統(tǒng)和新型裝備的附件等)的可靠性和生產規(guī)模問題。沒有規(guī)模就不會有高可靠性的產品;沒有規(guī)模就不會有價格低廉而富有競爭力的產品;當然,沒有規(guī)模中國的數(shù)控裝備最終難以有出頭之日。在高精尖裝備研發(fā)方面,要強調產、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。在競爭前數(shù)控技術方面,強調創(chuàng)新,強調研究開發(fā)具有自主知識產權的技術和產品,為我國數(shù)控產業(yè)、裝備制造業(yè)乃至整個制造業(yè)的可持續(xù)發(fā)展奠定基礎。參考文獻:[1]中國機床工具工業(yè)協(xié)會[J].世界制造技術與裝備市場,2001(3):1820.[2]梁訓王宣,[J].世界制造技術與裝備市場,2001(3):2128.[3]中國機床工具工業(yè)協(xié)會[J].世界制造技術與裝備市場,2001(5):1317.[4]楊學桐,李冬茹,何文立,等?距世紀數(shù)控機床技術發(fā)展戰(zhàn)略研究[M].北京:國家機械工業(yè)局,2000.附錄2 (外文原文)The number controls the technique and equips todevelop the trend and counterplansSummary:The synopsis introduced the world nowadays count control the trend and our countries of technique and material development number to control the present condition that equip the technique development and industries39。 turn, discussed on this foundation under the new surrounding that our country join the WTO and open outward to turn further and deeply, develop the our country the number controls the technique and equips, exaltation our country the manufacturing industry importance of the informationbased level and international petition ability, and put forward to develop the our country from two levels of strategy and strategy the number controls the technique and material of what time viewpoint. The technique level and the modernization degrees of the material industry decide the whole level of national economy and the modernization degree, the number controls the technique and materials are newly arisen and high new technique industry and sophisticated industry( such as the information technique and its industry, the living creature technique and its industry, aviationses, aerospace etc. the defence industry industry)s of developmentses to make the ability technique and the most basic mark think to have ever said various differentiation of economic ages, don39。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。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 control number the technique and numbers control the strategic supplies that the material lists as the nation, not only adopt the important measure to develop own number to control technique and its industries, and count to control the key technique and material in high point the aspect practices to blockade and limit the policy to the our fine, develop strongly with the number controls the technique for the advanced manufacturing technique of the core has bee the acceleration economy in each flourishing nation in world development, exaltation prehensive important path of the national strength and national position. The number control technique is exercise and work to the machine with the numerical information the process carries on the control of technique, the number control the material to make the industry and newly arisen manufacturing industries to permeate the formative machine electricity integral whole to turn the product to the tradition with the new technique that the number control the technique as representative, the namely socalled numeral masquerade to have, its technique scope overlay a lot of realms:(1)The machine manufacturing technique。(2)The information processing, process, deliver the technique。(3)Automatic control technique。(4)Servo drive the technique。(5)Spread the feeling machine technique。(6)Software technique etc.. 1 The number controls the technical development trend The number not only brought revolution variety for traditional manufacturing industry, make the manufacturing industry bee the symbol of the industrialization, but also control the technical application along with the number control technical develop continuously and applied realm of extension, he rises to some developments of important profession( IT, automobile, light work, medical treatment...etc.) of the national policy people39。s livelihood more and more important function, because big trend that the numeral of the material turns to is already the modern development that these professions currently in the world count control the technique and it equips the trend of the development to see, its main research is hot the point contain following 14 ]s of a few aspect [s. 1. one high speed, high processing technology of and new trend of the materials The efficiency, quantity is a forerunner to make the technical high speed, high processing technology of can lift biggest highefficiency, the quantity and the file times of the exaltation product, shorten to produce the period and exaltation market petition the technique research meeting to list as it to one of the 5 greatest moderns manufacturing technique first for this Japan, international produce the engineering academic association( CIRP) to is certain it to study one of the directions for 21 centuries of center. At the car industry realm, the year produces 300,000 production rhythm
