【正文】 n the precise and advanced equipment research and development aspect, must emphasize produces, studies, grinds as well as enduser39。 Numerical control technology application domain development dynamics is not strong。s numerical control industry base c. Has established a numerical control research, the development, managerial talent39。 Simplification programming, simplification operation aspect intellectualization, like intellectualized automatic programming, intellectualized manmachine contact surface and so on。s livelihood some important professions (IT, automobile, light industry, medical service and so on) development more and more vital role, because these professions must equip the digitization already was the modern development major tendency. The numerical control technology and the equipment development tendency looked from the present world that, its main research hot spot has following several aspect [1~4]. high speed, high precision work technology and equipment new tendency The efficiency, the quality are the advanced technique of manufacture main bodies. High speed, the high precision work technology may enhance the efficiency enormously, enhances the product the quality and the scale, reduces the production cycle and sharpens the market petition ability. Lists as one of 5 great modern techniques of manufacture for this Japan Tip Technology Research board it, the international production project learns (CIRP) its determination is one of 21st century central research directions. In the passenger vehicle industry domain, yearly produces 300,000 production metres was 40/s， moreover the multivariety processing is one of key questions which the passenger vehicle equipment must solve。 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(jīng)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(chǎn)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(chǎn)業(yè)化發(fā)展的支撐技術、配套技術作為研究開發(fā)的內(nèi)容，實現(xiàn)制造裝備業(yè)的跨躍式發(fā)展。雖然從縱向看我國的發(fā)展速度很快，但橫向比（與國外對比）不僅技術水平有差距，在某些方面發(fā)展速度也有差距，即一些高精尖的數(shù)控裝備的技術水平差距有擴大趨勢。 ，基本掌握了現(xiàn)代數(shù)控技術。 2 對我國數(shù)控技術及其產(chǎn)業(yè)發(fā)展的基本估計 我國數(shù)控技術起步于 1958年，近 50年的發(fā)展歷程大致可分為 3 個階段：第一階段從 1958年到 1979年，即封閉式發(fā)展階段。 STEPNC 的出現(xiàn)可能是數(shù)控技術領域的一次革命，對于數(shù)控技術的發(fā)展乃至整個制造業(yè)，將產(chǎn)生深遠的影響。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。 當前由于電主軸的出現(xiàn)，使得實現(xiàn) 5 軸聯(lián)動加工的復合主軸頭結(jié)構(gòu)大為簡化，其制造難度和成本大幅度降低，數(shù)控系統(tǒng)的價格差距縮小。美國 CINCINNATI 公司的 HyperMach機床進給速度最大達 60m/min，快速為 100m/min，加速度達 2g，主軸轉(zhuǎn)速已達 60 000r/min。 1． 1 高速、高精加工技術及裝備的新趨勢 效率、質(zhì)量是先進制造技術的主體。 在轎車工業(yè)領域，年產(chǎn) 30 萬輛的生產(chǎn)節(jié)拍是 40 秒 /輛，而且多品種加工是轎車裝備必須解決的重點問題之一；在航空和宇航工業(yè)領域，其加工的零部件多為薄壁和薄筋，剛度很差，材料為鋁 或鋁合金，只有在高切削速度和切削力很小的情況下，才能對這些筋、壁進行加工。 在可靠性方面，國外數(shù)控裝置的 MTBF值已達 6 000h以上，伺服系統(tǒng)的 MTBF值達到 30000h以上，表現(xiàn)出非常高的可靠性。德國 DMG 公司展出 DMUVoution 系列加工中心，可在一次裝夾下 5 面加工和 5 軸聯(lián)動加工，可由 CNC 系統(tǒng)控制或 CAD/CAM 直接或間接控制。 重視新技術標準、規(guī)范的建立 關于數(shù)控系統(tǒng)設計開發(fā)規(guī)范 如前所述，開放式數(shù)控系統(tǒng)有更好的通用性、柔性、適應性、擴展性，美國、歐共體和日本等國紛紛實施戰(zhàn)略發(fā)展計劃，并進行開放式體系結(jié)構(gòu)數(shù)控 系統(tǒng)規(guī)范 (OMAC、 OSACA、OSEC)的研究和制定，世界 3 個最大的經(jīng)濟體在短期內(nèi)進行了幾乎相同的科學計劃和規(guī)范的制定，預示了數(shù)控技術的一個新的變革時期的來臨。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％）。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。在攻關成果和部分技術商品化的基礎上，建立了諸如華中數(shù)控、航天數(shù)控等具有批量生產(chǎn)能力的數(shù)控系統(tǒng)生產(chǎn)廠。 ，市場占有率低，品種覆蓋率小，還沒有形成規(guī)模生產(chǎn)；功能部件專業(yè)化生 產(chǎn)水平及成套能力較低；外觀質(zhì)量相對差；可靠性不高，商品化程度不足；國產(chǎn)數(shù)控系統(tǒng)尚未建立自己的品牌效應，用戶信心不足。沒有規(guī)模就不會有高可靠性的產(chǎn)品；沒有規(guī)模就不會有價格低廉而富有競爭力的產(chǎn)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。s HyperMach engine bed feed rate reaches 60m/most greatlymin, fast is 100m/min, the acceleration reaches 2g, the main axle rotational speed has reached 60 000r/min. Processes a thin wall airplane part, only uses 30min, but the same ponents need 3h in the mon high speed milling machine processing, needs 8h in the plain milling machine processing。s special application and the technical knack in the control system, the fast realization different variety, the different scale open style numerical control system, forms has the bright individuality famous brand goods. At present the open style numerical control system architecture standard, the correspondence standard, the disposition standard, the movement platform, the numerical control system function storehouse as well as the numerical control system function software development kit and so on is the current research core. takes the new technical standard, the standard establishment about numerical control system design development standard As mentioned above, the open style numerical control system has a better versatility, the flexibility, the patibility, the extension, countries and so on US, European Economic Community and Japan implements the strategy development plan in abundance, and carries on the open style architecture numerical control system specification (OMAC, OSACA, OSEC) the research and the formulation, the world 3 biggest economies have carried on the nearly same science plan and the standard formulation in the shortterm, has indicated a numerical control technology new transformation time oning. Our country also started in 2020 to conduct China39。s development speed is very quick, not only but crosswise pared to (with overseas contrast) the technical level has the disparity, also has the disparity in certain aspect development speed, namely some precise and advanced numerical control equipment technical level disparity has the expanded tendency. From international looked that, is approximately as follows to our country numerical control technical level and the industrial production level estimate. a. In the technical level, probably falls behind with the overseas advanced level for 10~15 years, in precise and advanced technical aspect then bigger. b. In the industrial production level, the market share is low, the variety coverage fraction is small, but also has not formed the scale production。s stability。
