YF-D8070型數控雕銑機是一種能夠裝(zhuang)載數控(kong)雕(diao)(diao)銑(xian)(xian)(xian)(xian)程(cheng)(cheng)序(xu)自動(dong)控(kong)制(zhi)雕(diao)(diao)銑(xian)(xian)(xian)(xian)機(ji)運(yun)(yun)動(dong)的(de)加(jia)工系(xi)統(tong)，它通(tong)常(chang)由(you)(you)雕(diao)(diao)銑(xian)(xian)(xian)(xian)程(cheng)(cheng)序(xu)計算系(xi)統(tong)(包括計算機(ji)和(he)雕(diao)(diao)銑(xian)(xian)(xian)(xian)軟(ruan)件(jian))、數控(kong)裝(zhuang)置、主(zhu)軸控(kong)制(zhi)系(xi)統(tong)和(he)進(jin)給控(kong)制(zhi)系(xi)統(tong)組成(cheng)。雕(diao)(diao)銑(xian)(xian)(xian)(xian)程(cheng)(cheng)序(xu)計算系(xi)統(tong)由(you)(you)計算機(ji)和(he)雕(diao)(diao)銑(xian)(xian)(xian)(xian)軟(ruan)件(jian)組成(cheng)，在電腦上通(tong)過(guo)雕(diao)(diao)銑(xian)(xian)(xian)(xian)軟(ruan)件(jian)將需要雕(diao)(diao)銑(xian)(xian)(xian)(xian)的(de)圖(tu)形數字化，生成(cheng)每個步驟的(de)雕(diao)(diao)銑(xian)(xian)(xian)(xian)程(cheng)(cheng)序(xu)。雕(diao)(diao)銑(xian)(xian)(xian)(xian)程(cheng)(cheng)序(xu)是由(you)(you)一系(xi)列連續的(de)數控(kong)指令組成(cheng)的(de)，用來控(kong)制(zhi)主(zhu)軸轉速(su)、進(jin)給速(su)度(du)、換刀、運(yun)(yun)動(dong)暫(zan)停等。因為這些指令最(zui)終都是為刀具運(yun)(yun)動(dong)服務的(de)，所以雕(diao)(diao)銑(xian)(xian)(xian)(xian)程(cheng)(cheng)序(xu)也稱為刀具路徑文件(jian)。

　　雕(diao)銑(xian)軟(ruan)件根據設計圖(tu)樣和刀(dao)具(ju)自動(dong)計算(suan)出刀(dao)具(ju)的(de)運(yun)動(dong)位置，即刀(dao)位點，并(bing)將它們寫入雕(diao)銑(xian)程(cheng)序。數控(kong)系統(tong)從雕(diao)銑(xian)程(cheng)序中讀取刀(dao)位點之后自動(dong)計算(suan)各個坐(zuo)標軸的(de)運(yun)動(dong)分量，連續發送脈沖給電機，以控(kong)制(zhi)各個軸的(de)運(yun)動(dong)，最終完(wan)(wan)成實(shi)際的(de)雕(diao)銑(xian)加工。完(wan)(wan)整的(de)雕(diao)銑(xian)程(cheng)序包(bao)括如(ru)下指令：

　　1)刀具指令，包括換刀、對刀等；

　　2)主(zhu)軸(zhou)指令，包(bao)括主(zhu)軸(zhou)的開停、主(zhu)軸(zhou)轉速；

　　3)運(yun)動指令，包括(kuo)快速(su)定位、走直線、走圓弧(hu)、走樣條及走刀(dao)速(su)度；

　　4)其他指(zhi)令(ling)，包括冷卻系(xi)統的狀態、照明系(xi)統的狀態等。
