Abstract
　　　　
　　　The current trend and present situation in the developm ent of numerical controlled technology technology athome and abroad is troduced.It also introduces the invention,development,and future trend of numerical machine tool from the aspects of capacity,unction and structuer.This article confirms that the numerical control system which is developing and researching atpresent will certainly become reality.This kind of intelligent,flexible and featuer-rich sysrem adapts to complexmanufacturing rocesses,and has a closed-loop control structure.At last,technological theory in the developing direction is put forward.
　　　Key words: CNC techonlogy; The CNC system; development trend; fuction; architecture

　　　　摘 要
　　　　
　　　本文介紹了當(dāng)今數(shù)控技術(shù)發(fā)展的趨勢及國內(nèi)外數(shù)控技術(shù)發(fā)展的現(xiàn)狀，從性能、功能和體系結(jié)構(gòu)三個方面，介紹了數(shù)控機(jī)床的產(chǎn)生、數(shù)控技術(shù)的發(fā)展以及未來數(shù)控技術(shù)發(fā)展的方向，肯定了當(dāng)前在開發(fā)和研究的數(shù)控系統(tǒng)必將成為現(xiàn)實，這種智能化、柔性化的多功能系統(tǒng)，適應(yīng)于復(fù)雜制造過程，具有閉環(huán)控制體系結(jié)構(gòu)，還提出了符合未來數(shù)控技術(shù)發(fā)展方向的關(guān)鍵技術(shù)理論。
