【正文】 動化、數(shù)字化、柔性化、信息化、集成化、網(wǎng)絡(luò)化的基礎(chǔ)，是現(xiàn)代機床裝備的靈魂和核心，有著廣泛的應(yīng)用領(lǐng)域和廣闊的應(yīng)用前景。當(dāng)今世界各國制造業(yè)廣泛采用數(shù)控技術(shù)，以提高制造能力和水平，提高對動態(tài)多變市場的適應(yīng)能力和競爭能力。2 國內(nèi)外數(shù)控系統(tǒng)的發(fā)展概況 隨著計算機技術(shù)的高速發(fā)展，傳統(tǒng)的制造業(yè)開始了根本性變革，各工業(yè)發(fā)達國家投入巨資，對現(xiàn)代制造技術(shù)進行研究開發(fā)，提出了全新的制造模式。 長期以來，我國的數(shù)控系統(tǒng)為傳統(tǒng)的封閉式體系結(jié)構(gòu)，CNC只能作為非智能的機床運動控制器。由此可見，傳統(tǒng)CNC系統(tǒng)的這種固定程序控制模式和封閉式體系結(jié)構(gòu)，限制了CNC向多變量智能化控制發(fā)展，己不適應(yīng)日益復(fù)雜的制造過程，因此，大力發(fā)展以數(shù)控技術(shù)為核心的先進制造技術(shù)已成為我們國家加速經(jīng)濟發(fā)展、提高綜合國力和國家地位的重要途徑。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)周期和提高市場競爭能力。這些都對加工裝備提出了高速、高精和高柔性的要求。當(dāng)前由于電主軸的出現(xiàn)，使得實現(xiàn)5軸聯(lián)動加工的復(fù)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。 目前許多國家對開放式數(shù)控系統(tǒng)進行研究，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(luò)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(chǔ)單元。 參考文獻 [1] 王立新. 淺談數(shù)控技術(shù)的發(fā)展趨勢[J]. 赤峰學(xué)院學(xué)報，2007.

Keywords: CNC Technology Trends Smart CNC technology is a set of puter technology, automation and control technology, measurement technology, modern machinery manufacturing technology, microelectronics, information processing technology, an integrated multidisciplinary crosstechnology, application areas in recent years developed very rapidly in a prehensive hightech. It is to meet the highprecision, high speed, plex parts processing and there is automatic, digital, flexible, informationoriented, integrated, networkbased foundation, the soul of modern machine tools and equipment and the core, has a wide range of application fields and broad application prospects. 1, numerical control technology and equipment development trends and countermeasures The equipment industry39。 (2) information processing, processing and transmission technology。 (6) software technology. Second, the development of numerical control system at home and abroad overviewWith the rapid development of puter technology, the traditional manufacturing industries began a fundamental change, the industrialized countries invested heavily in modern manufacturing technology research and development and put forward a new manufacturing model. In modern manufacturing systems, numerical control technology is the key technology, which bines microelectronics, puter, information processing, automatic detection, automatic control and other hightech in one, with high precision, high efficiency, flexibility and automation features to achieve flexible manufacturing automation, integrated, intelligent play a decisive role. At present, the numerical control technology is undergoing a fundamental transformation, from specialpurpose closedopenloop control mode to the generalpurpose realtime dynamic openloop control mode. In an integrated basis, numerical control system to realize ultrathin, ultrasmall。 in aviation and aerospace industry, its processing parts are mostly thinwalled and thin bars, stiffness is poor, aluminum or aluminum alloy material, and only at high cutting speed and cutting force in the case of a small can of these ribs,
