其(qi)實就是數(shu)控(kong)(kong)銑床(chuang)，在廣、江浙滬一帶有(you)人叫“CNC加工(gong)(gong)中心”，是一種裝(zhuang)有(you)程序控(kong)(kong)制系統(tong)的自動(dong)化(hua)機(ji)(ji)(ji)床(chuang)。(數(shu)控(kong)(kong)機(ji)(ji)(ji)床(chuang))是計算(suan)機(ji)(ji)(ji)數(shu)字控(kong)(kong)制機(ji)(ji)(ji)床(chuang)(Computer numerical control)的簡稱，是一種由程序控(kong)(kong)制的自動(dong)化(hua)機(ji)(ji)(ji)床(chuang)。該控(kong)(kong)制系統(tong)能夠邏輯地處理(li)具(ju)有(you)控(kong)(kong)制編碼(ma)或其(qi)他符號(hao)指令規定(ding)的程序，通(tong)過計算(suan)機(ji)(ji)(ji)將其(qi)譯(yi)碼(ma)，從而使機(ji)(ji)(ji)床(chuang)動(dong)作(zuo)并加工(gong)(gong)零件。通(tong)過刀具(ju)切削將毛(mao)坯料加工(gong)(gong)成半成品(pin)成品(pin)零件等。

CNC加(jia)(jia)(jia)工(gong)(gong)（CNC Machining）數(shu)控(kong)加(jia)(jia)(jia)工(gong)(gong)是(shi)指用數(shu)控(kong)的加(jia)(jia)(jia)工(gong)(gong)工(gong)(gong)具進(jin)行的加(jia)(jia)(jia)工(gong)(gong)。CNC指數(shu)控(kong)機床由數(shu)控(kong)加(jia)(jia)(jia)工(gong)(gong)語言進(jin)行編程(cheng)控(kong)制，通常為G代碼。數(shu)控(kong)加(jia)(jia)(jia)工(gong)(gong)G代碼語言告訴(su)數(shu)控(kong)機床的加(jia)(jia)(jia)工(gong)(gong)刀(dao)具采用何種笛卡爾位置坐(zuo)標，并控(kong)制刀(dao)具的進(jin)給速(su)度和主軸轉速(su)，以(yi)及(ji)工(gong)(gong)具變換(huan)器(qi)、冷(leng)卻劑等(deng)功能。

數(shu)(shu)控(kong)加(jia)工(gong)(gong)相(xiang)對手(shou)動加(jia)工(gong)(gong)具有很大(da)的優勢(shi)，如數(shu)(shu)控(kong)加(jia)工(gong)(gong)生產出(chu)的零件(jian)非常精確并具有可重(zhong)復(fu)(fu)性；數(shu)(shu)控(kong)加(jia)工(gong)(gong)可以(yi)生產手(shou)動加(jia)工(gong)(gong)無法完成的具有復(fu)(fu)雜外形的零件(jian)。數(shu)(shu)控(kong)加(jia)工(gong)(gong)技(ji)術現已普遍推廣，大(da)多數(shu)(shu)的機加(jia)工(gong)(gong)車間都(dou)具有數(shu)(shu)控(kong)加(jia)工(gong)(gong)能力(li)，典型的機加(jia)工(gong)(gong)車間中最常見的數(shu)(shu)控(kong)加(jia)工(gong)(gong)方式有數(shu)(shu)控(kong)銑、數(shu)(shu)控(kong)車和數(shu)(shu)控(kong)EDM線切割(ge)（電火花線切割(ge)）。

進行(xing)數(shu)(shu)(shu)(shu)控(kong)(kong)(kong)(kong)銑的工具叫(jiao)做(zuo)數(shu)(shu)(shu)(shu)控(kong)(kong)(kong)(kong)銑床或數(shu)(shu)(shu)(shu)控(kong)(kong)(kong)(kong)加工中心(xin)(xin)。進行(xing)數(shu)(shu)(shu)(shu)控(kong)(kong)(kong)(kong)車(che)削加工的車(che)床叫(jiao)做(zuo)數(shu)(shu)(shu)(shu)控(kong)(kong)(kong)(kong)車(che)工中心(xin)(xin)。數(shu)(shu)(shu)(shu)控(kong)(kong)(kong)(kong)加工G代(dai)碼可以人工編程，但通常(chang)機(ji)(ji)加工車(che)間用CAM（計算(suan)機(ji)(ji)輔(fu)(fu)助(zhu)制造）軟件自動讀取(qu)CAD（計算(suan)機(ji)(ji)輔(fu)(fu)助(zhu)設計）文件并生成(cheng)G代(dai)碼程序，對數(shu)(shu)(shu)(shu)控(kong)(kong)(kong)(kong)機(ji)(ji)床進行(xing)控(kong)(kong)(kong)(kong)制。
