數控車床(chuang)是使用較為廣泛的數控機床(chuang)之一。它主(zhu)要用于軸類(lei)零件或盤類(lei)零件的內(nei)外(wai)圓(yuan)(yuan)柱面、任意錐角的內(nei)外(wai)圓(yuan)(yuan)錐面、復(fu)雜(za)回轉內(nei)外(wai)曲面和(he)圓(yuan)(yuan)柱、圓(yuan)(yuan)錐螺紋等切削加工，并能進行切槽、鉆孔、擴孔、鉸孔及鏜(tang)孔等。

數(shu)控機(ji)(ji)床(chuang)是按照事先編制好(hao)的(de)(de)(de)加(jia)工(gong)(gong)(gong)程(cheng)序，自動地對被加(jia)工(gong)(gong)(gong)零件進行加(jia)工(gong)(gong)(gong)。我(wo)們把(ba)零件的(de)(de)(de)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝路線、工(gong)(gong)(gong)藝參數(shu)、刀具的(de)(de)(de)運動軌(gui)跡、位移量、切削參數(shu)以及(ji)輔助功(gong)能(neng)，按照數(shu)控機(ji)(ji)床(chuang)規定的(de)(de)(de)指(zhi)令代碼及(ji)程(cheng)序格式編寫(xie)成加(jia)工(gong)(gong)(gong)程(cheng)序單，再把(ba)這(zhe)程(cheng)序單中的(de)(de)(de)內容記錄在控制介質上，然后輸入到(dao)數(shu)控機(ji)(ji)床(chuang)的(de)(de)(de)數(shu)控裝(zhuang)置(zhi)中，從而(er)指(zhi)揮機(ji)(ji)床(chuang)加(jia)工(gong)(gong)(gong)零件。
