其(qi)實就是(shi)(shi)數控銑(xian)床(chuang)(chuang)(chuang)(chuang)，在廣、江浙滬一(yi)帶有(you)人(ren)叫“CNC加(jia)工中心”，是(shi)(shi)一(yi)種(zhong)(zhong)裝(zhuang)有(you)程序控制(zhi)系(xi)統(tong)的自動(dong)化機(ji)床(chuang)(chuang)(chuang)(chuang)。(數控機(ji)床(chuang)(chuang)(chuang)(chuang))是(shi)(shi)計(ji)算機(ji)數字控制(zhi)機(ji)床(chuang)(chuang)(chuang)(chuang)(Computer numerical control)的簡稱，是(shi)(shi)一(yi)種(zhong)(zhong)由程序控制(zhi)的自動(dong)化機(ji)床(chuang)(chuang)(chuang)(chuang)。該控制(zhi)系(xi)統(tong)能夠邏(luo)輯地處理具有(you)控制(zhi)編碼或其(qi)他符(fu)號(hao)指令規定的程序，通過(guo)計(ji)算機(ji)將(jiang)(jiang)其(qi)譯碼，從而(er)使機(ji)床(chuang)(chuang)(chuang)(chuang)動(dong)作并加(jia)工零(ling)件。通過(guo)刀具切削將(jiang)(jiang)毛坯料加(jia)工成(cheng)半成(cheng)品成(cheng)品零(ling)件等。

CNC加(jia)工(gong)(gong)（CNC Machining）數(shu)控(kong)加(jia)工(gong)(gong)是(shi)指(zhi)用數(shu)控(kong)的(de)加(jia)工(gong)(gong)工(gong)(gong)具(ju)(ju)(ju)進(jin)(jin)行的(de)加(jia)工(gong)(gong)。CNC指(zhi)數(shu)控(kong)機(ji)床由數(shu)控(kong)加(jia)工(gong)(gong)語言進(jin)(jin)行編程控(kong)制，通常為G代碼。數(shu)控(kong)加(jia)工(gong)(gong)G代碼語言告(gao)訴(su)數(shu)控(kong)機(ji)床的(de)加(jia)工(gong)(gong)刀(dao)具(ju)(ju)(ju)采用何(he)種笛卡爾位置(zhi)坐標(biao)，并控(kong)制刀(dao)具(ju)(ju)(ju)的(de)進(jin)(jin)給速度和主軸轉速，以及工(gong)(gong)具(ju)(ju)(ju)變換(huan)器、冷卻劑(ji)等功能(neng)。

數(shu)(shu)控(kong)加(jia)工相對手動加(jia)工具(ju)有(you)很大的優勢，如數(shu)(shu)控(kong)加(jia)工生產(chan)出的零件非常精確并(bing)具(ju)有(you)可重(zhong)復性；數(shu)(shu)控(kong)加(jia)工可以生產(chan)手動加(jia)工無法(fa)完成的具(ju)有(you)復雜外形(xing)的零件。數(shu)(shu)控(kong)加(jia)工技術現已(yi)普遍推廣(guang)，大多(duo)數(shu)(shu)的機加(jia)工車(che)(che)間(jian)都具(ju)有(you)數(shu)(shu)控(kong)加(jia)工能力，典型的機加(jia)工車(che)(che)間(jian)中(zhong)最常見的數(shu)(shu)控(kong)加(jia)工方式(shi)有(you)數(shu)(shu)控(kong)銑、數(shu)(shu)控(kong)車(che)(che)和數(shu)(shu)控(kong)EDM線切割（電火花線切割）。

進(jin)行數(shu)控(kong)(kong)銑的工(gong)具(ju)叫做(zuo)數(shu)控(kong)(kong)銑床(chuang)或數(shu)控(kong)(kong)加工(gong)中心。進(jin)行數(shu)控(kong)(kong)車削(xue)加工(gong)的車床(chuang)叫做(zuo)數(shu)控(kong)(kong)車工(gong)中心。數(shu)控(kong)(kong)加工(gong)G代(dai)(dai)碼可以人(ren)工(gong)編程(cheng)，但(dan)通常機(ji)加工(gong)車間用CAM（計算機(ji)輔助(zhu)制(zhi)造）軟件自動讀(du)取CAD（計算機(ji)輔助(zhu)設計）文(wen)件并生成G代(dai)(dai)碼程(cheng)序，對數(shu)控(kong)(kong)機(ji)床(chuang)進(jin)行控(kong)(kong)制(zhi)。
