there are intelligent diagnosis, intelligent control aspects, to facilitate the system diagnosis and maintenance. To address the traditional closed and CNC numerical control system application software industrial production problems. At present, many countries conduct a study of open CNC system, CNC system and opening up has bee a numerical control system of the future path. The socalled openarchitecture CNC system is the development of numerical control system can be run in a unified platform for machine tool manufacturers and end users, by changing, adding or cutting the structure object (numerical control function), the formation of serialization, and can be easily user39。1. Highprecision, highspeed development trend Although more than 10 years ago, the trend appeared in highprecision highspeed, but the scientific and technological development is not enough, highprecision, highspeed is also changing the connotation of being towards the development of accuracy and speed limits. Efficiency, quality is the main body of advanced manufacturing technology. Highspeed, highfinishing technology can greatly improve efficiency, improve product quality and grades, and shorten the production cycle and improve market petitiveness. To this end, Japan will study advanced technologies listed it as one of five major modern manufacturing technology, the International Institute of Production Engineering be identified as the 21st century, one of the central research directions. In the car industry, the production of an annual output of 300,000 beat is 40 seconds / vehicle, and most varieties of processing is a car equipped with one of the key issues that must be addressed。s livelihood some of the important development of the industry plays a an increasingly important role. NC from the current world trend of technological development, mainly the following aspects: (5) sensor technology。CNC technology is to use digital information on the mechanical movement and the work process control technology, CNC numerical control technology and equipment is represented by new technologies on traditional manufacturing industries and the penetration of the formation of new manufacturing electromechanical integrated product, socalled digital equipment , and its technology, covering many areas: (1) Mechanical manufacturing technology。s developed countries to accelerate economic development, enhance overall national strength and an important way to statehood. 文中簡要陳述當前的發(fā)展趨勢,另外數(shù)控技術的正不斷走向集成化,并行化,仍有廣闊的發(fā)展空間。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。為解決傳統(tǒng)的數(shù)控系統(tǒng)封閉性和數(shù)控應用軟件的產(chǎn)業(yè)化生產(chǎn)存在的問題。但過去因5軸聯(lián)動數(shù)控系統(tǒng)、主機結構復雜等原因,其價格要比3軸聯(lián)動數(shù)控機床高出數(shù)倍,加之編程技術難度較大,制約了5軸聯(lián)動機床的發(fā)展。近來采用大型整體鋁合金坯料掏空的方法來制造機翼、機身等大型零件來替代多個零件通過眾多的鉚釘、螺釘和其他聯(lián)結方式拼裝,使構件的強度、剛度和可靠性得到提高。 效率、質量是先進制造技術的主體。在復雜環(huán)境以及多變條件下,加工過程中的刀具組合、工件材料、主軸轉速、進給速率、刀具軌跡、切削深度、步長、加工余量等加工參數(shù),無法在現(xiàn)場環(huán)境下根據(jù)外部干擾和隨機因素實時動態(tài)調(diào)整,更無法通過反饋控制環(huán)節(jié)隨機修正CAD/CAM中的設定量,因而影響CNC的工作效率和產(chǎn)品加工質量。在集成化基礎上,數(shù)控系統(tǒng)實現(xiàn)了超薄型、超小型化;在智能化基礎上,綜合了計算機、多媒體、模糊控制、神經(jīng)網(wǎng)絡等多學科技術,數(shù)控系統(tǒng)實現(xiàn)了高速、高精、高效控制,加工過程中可以自動修正、調(diào)節(jié)與補償各項參數(shù),實現(xiàn)了在線診斷和智能化故障處理。 數(shù)控技術是用數(shù)字信息對機械運動和工作過程進行控制的技術,數(shù)控裝備是以數(shù)控技術為代表的新技術對傳統(tǒng)制造產(chǎn)業(yè)和新興制造業(yè)的滲透形成的機電一體化產(chǎn)品,即所謂的數(shù)字化裝備,其技術范圍覆蓋很多領域:(1)機械制造技術;(2)信息處理、加工、傳輸技術;(3)自動控制技術;(4)伺服驅動技術;(5)傳感器技術;(6)軟件技術等。制造技術和裝備就是人類生產(chǎn)活動的最基本的生產(chǎn)資料,而數(shù)控技術又是當今先進制造技術和裝備最核心的技術。關鍵詞 數(shù)控技術 趨勢 智能 數(shù)控技術是一門集計算機技術、自動化控制技術、測量技術、現(xiàn)代機械制造技術、微電子技術、信息處理技術等多學科交叉的綜合技術,是近年來應用領域中發(fā)展十分迅速的一項綜合性的高新技術。 指導教師評語:此翻譯文章結合國內(nèi)外情況,分析了數(shù)控技術的發(fā)展趨勢。翻譯用詞比較準確,文筆也較為通順,為在以后工作中接觸英文資料打下了基礎。它是為適應高精度、高速度、復雜零件的加工而出現(xiàn)的,是實現(xiàn)自
