其實就是(shi)數(shu)控(kong)(kong)(kong)(kong)銑床(chuang)(chuang)，在廣(guang)、江浙滬一帶(dai)有(you)(you)人(ren)叫“CNC加(jia)工zhong心”，是(shi)一種裝有(you)(you)程(cheng)(cheng)序控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)的自動化機(ji)(ji)床(chuang)(chuang)。(數(shu)控(kong)(kong)(kong)(kong)機(ji)(ji)床(chuang)(chuang))是(shi)計算機(ji)(ji)數(shu)字控(kong)(kong)(kong)(kong)制(zhi)(zhi)機(ji)(ji)床(chuang)(chuang)(Computer numerical control)的簡稱，是(shi)一種由程(cheng)(cheng)序控(kong)(kong)(kong)(kong)制(zhi)(zhi)的自動化機(ji)(ji)床(chuang)(chuang)。該控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)能(neng)夠邏輯(ji)地處理具(ju)有(you)(you)控(kong)(kong)(kong)(kong)制(zhi)(zhi)編(bian)碼或其他(ta)符號(hao)指令規定(ding)的程(cheng)(cheng)序，通過計算機(ji)(ji)將其譯(yi)碼，從而(er)使機(ji)(ji)床(chuang)(chuang)動作并加(jia)工零件。通過刀具(ju)切削將毛坯料加(jia)工成半成品成品零件等(deng)。

CNC加(jia)(jia)工（CNC Machining）數(shu)(shu)(shu)控(kong)(kong)(kong)(kong)加(jia)(jia)工是指(zhi)用數(shu)(shu)(shu)控(kong)(kong)(kong)(kong)的加(jia)(jia)工工具進行的加(jia)(jia)工。CNC指(zhi)數(shu)(shu)(shu)控(kong)(kong)(kong)(kong)機(ji)床由數(shu)(shu)(shu)控(kong)(kong)(kong)(kong)加(jia)(jia)工語言(yan)進行編程控(kong)(kong)(kong)(kong)制，通(tong)常(chang)為G代碼(ma)。數(shu)(shu)(shu)控(kong)(kong)(kong)(kong)加(jia)(jia)工G代碼(ma)語言(yan)告訴數(shu)(shu)(shu)控(kong)(kong)(kong)(kong)機(ji)床的加(jia)(jia)工刀具采用何(he)種笛卡(ka)爾位(wei)置坐標，并(bing)控(kong)(kong)(kong)(kong)制刀具的進給速度和主軸轉(zhuan)速，以及(ji)工具變換器、冷卻劑等功能(neng)。
