數(shu)控(kong)機(ji)(ji)(ji)床是按照事先編制好的加(jia)(jia)工(gong)(gong)程(cheng)序，自(zi)動(dong)地對被加(jia)(jia)工(gong)(gong)零件(jian)進行加(jia)(jia)工(gong)(gong)。我們把零件(jian)的加(jia)(jia)工(gong)(gong)工(gong)(gong)藝(yi)路線、工(gong)(gong)藝(yi)參數(shu)、刀具(ju)的運動(dong)軌(gui)跡、位(wei)移量、切(qie)削參數(shu)以及輔助功能(neng)，按照數(shu)控(kong)機(ji)(ji)(ji)床規(gui)定的指(zhi)令(ling)代碼及程(cheng)序格式編寫成(cheng)加(jia)(jia)工(gong)(gong)程(cheng)序單，再把這程(cheng)序單中的內容記錄在控(kong)制介質上，然后(hou)輸入到數(shu)控(kong)機(ji)(ji)(ji)床的數(shu)控(kong)裝置中，從而指(zhi)揮機(ji)(ji)(ji)床加(jia)(jia)工(gong)(gong)零件(jian)。
