4、計(jì)算機(jī),包括計(jì)算機(jī)數(shù)字控制系統(tǒng)的基礎(chǔ)。數(shù)控技術(shù)是與機(jī)床控制密切結(jié)合發(fā)展起來的。1952年,第一臺(tái)數(shù)控機(jī)床問世,成為世界機(jī)械工業(yè)史上一件劃時(shí)代的事件,推動(dòng)了自動(dòng)化的發(fā)展。13現(xiàn)在,數(shù)控技術(shù)也叫計(jì)算機(jī)數(shù)控技術(shù),目前它是采用計(jì)算機(jī)實(shí)現(xiàn)數(shù)字程序控制的技術(shù)。這種技術(shù)用計(jì)算機(jī)按事先存貯的控制程序來執(zhí)行對(duì)設(shè)備的控制功能。由于采用計(jì)算機(jī)替代原先用硬件邏輯電路組成的數(shù)控裝置,使輸入數(shù)據(jù)的存貯、處理、運(yùn)算、邏輯判斷等各種控制機(jī)能的實(shí)現(xiàn),均可通過計(jì)算機(jī)軟件來完成。數(shù)控技術(shù)的應(yīng)用不但給傳統(tǒng)制造業(yè)帶來了革命性的變化,使制
5、造業(yè)成為工業(yè)化的象征,而且隨著數(shù)控技術(shù)的不斷發(fā)展和應(yīng)用領(lǐng)域的擴(kuò)大,他對(duì)國(guó)計(jì)民生的一些重要行業(yè)(IT、汽車、輕工、醫(yī)療等)的發(fā)展起著越來越重要的作用。關(guān)鍵詞:數(shù)控技術(shù),數(shù)控加工,工藝分析AbstractCNCtechnologyistheuseofnumbers,wordsandsymbolsofthedigitalcommandtoachieveoneormoremechanicalequipment,motioncontroltechnology.Itisusuallycontrolledby
