    南露醬

    很多人不了解數(shù)控車簡(jiǎn)單零件綜合編程,下面就給大家看一下數(shù)控車簡(jiǎn)單零件綜合編程實(shí)例。

    確定加工路線:按先主后次,先粗后精的加工原則確定加工路線,采用固定循環(huán)指令對(duì)外輪廓進(jìn)行粗加工,再精加工,然后車退刀槽,再加工螺紋,最后切斷。

    裝夾方法和對(duì)刀點(diǎn)的選擇:采用三爪自定心卡盤自定心夾緊,對(duì)刀點(diǎn)選在工件的右端面與回轉(zhuǎn)軸線的交點(diǎn)。

    刀具的選擇:

    根據(jù)加工要求,選用四把刀,1號(hào)為粗加工外圓車刀,2號(hào)為精加工外圓車刀,3號(hào)為切槽刀,4號(hào)為車螺紋刀。采用試切法對(duì)刀,對(duì)刀的同時(shí)把端面加工出來(lái)。
