機械加工中加工機床的運動

    CA6140型(xing)普通(tong)車床只備加工各(ge)種(zhong)回轉表面所必須的(de)(de)(de)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)：工件(jian)的(de)(de)(de)旋轉運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，刀(dao)(dao)(dao)具(ju)作(zuo)平(ping)(ping)行(xing)于工件(jian)中心(xin)線(xian)的(de)(de)(de)縱(zong)(zong)(zong)向(xiang)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)和(he)刀(dao)(dao)(dao)具(ju)作(zuo)垂直于工件(jian)中心(xin)線(xian)的(de)(de)(de)橫(heng)向(xiang)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)。其(qi)中，工件(jian)的(de)(de)(de)旋轉運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)稱(cheng)為(wei)(wei)主(zhu)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)。主(zhu)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)速度較高，消耗的(de)(de)(de)功(gong)凈較多，常以n表示。刀(dao)(dao)(dao)具(ju)的(de)(de)(de)縱(zong)(zong)(zong)向(xiang)或橫(heng)向(xiang)直線(xian)移(yi)(yi)動(dong)(dong)(dong)(dong)(dong)稱(cheng)為(wei)(wei)進(jin)給(gei)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)。進(jin)給(gei)遠(yuan)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)速度較低，消極的(de)(de)(de)功(gong)率也較少，刀(dao)(dao)(dao)具(ju)作(zuo)平(ping)(ping)行(xing)于工件(jian)中心(xin)線(xian)的(de)(de)(de)縱(zong)(zong)(zong)向(xiang)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)稱(cheng)為(wei)(wei)縱(zong)(zong)(zong)向(xiang)進(jin)給(gei)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，其(qi)進(jin)給(gei)量以工件(jian)每轉刀(dao)(dao)(dao)具(ju)縱(zong)(zong)(zong)向(xiang)移(yi)(yi)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)距離f縱(zong)(zong)(zong)表示。
