五軸加工中心作為自動化程度高(gao)(gao)的智能(neng)加(jia)工(gong)(gong)(gong)設備常被用(yong)于(yu)高(gao)(gao)端制造中。五軸(zhou)加(jia)工(gong)(gong)(gong)中心(xin)適合加(jia)工(gong)(gong)(gong)自由曲面(mian)的機(ji)體零部件、飛機(ji)輪船(chuan)上的渦輪機(ji)零部件和(he)葉輪。我們可以發現適合五軸(zhou)加(jia)工(gong)(gong)(gong)中心(xin)加(jia)工(gong)(gong)(gong)的工(gong)(gong)(gong)件都具有曲面(mian)程度高(gao)(gao)，通(tong)過(guo)一次(ci)裝夾難(nan)以加(jia)工(gong)(gong)(gong)成型的特點，因(yin)此五軸(zhou)機(ji)床(chuang)可以不改變(bian)工(gong)(gong)(gong)件在(zai)機(ji)床(chuang)上的位置，對工(gong)(gong)(gong)件的不同(tong)側面(mian)進行(xing)加(jia)工(gong)(gong)(gong)，大(da)大(da)提高(gao)(gao)棱柱(zhu)形零件的加(jia)工(gong)(gong)(gong)效(xiao)率。

五軸(zhou)(zhou)加工(gong)中(zhong)心具有(you)X、Y、Z三個(ge)移動軸(zhou)(zhou)和(he)任意(yi)兩個(ge)旋轉軸(zhou)(zhou)，相(xiang)對于傳統的三軸(zhou)(zhou)加工(gong)中(zhong)心而(er)言，五軸(zhou)(zhou)加工(gong)中(zhong)心的五軸(zhou)(zhou)聯動技術在(zai)加工(gong)幾何形狀比較復雜的工(gong)件(jian)時，刀具能夠在(zai)五個(ge)自由度(du)上進(jin)行定位和(he)操作。

很多朋友在(zai)認知五軸(zhou)(zhou)加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)心方面(mian)存(cun)在(zai)一個誤區，認為五軸(zhou)(zhou)加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)心就(jiu)是(shi)(shi)在(zai)三軸(zhou)(zhou)加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)心的(de)基礎上(shang)，添加(jia)(jia)(jia)2個旋轉(zhuan)軸(zhou)(zhou)。這(zhe)兩個旋轉(zhuan)軸(zhou)(zhou)先將切削刀(dao)具固(gu)定(ding)在(zai)一個傾斜位置(zhi)，再由(you)(you)進給軸(zhou)(zhou)X、Y、Z進行移動(dong)和加(jia)(jia)(jia)工(gong)(gong)(gong)。這(zhe)種加(jia)(jia)(jia)工(gong)(gong)(gong)方式實(shi)際上(shang)是(shi)(shi)由(you)(you)于(yu)第四軸(zhou)(zhou)和第五軸(zhou)(zhou)是(shi)(shi)用來確(que)定(ding)在(zai)固(gu)定(ding)位置(zhi)上(shang)刀(dao)具的(de)方向，而不(bu)(bu)是(shi)(shi)在(zai)加(jia)(jia)(jia)工(gong)(gong)(gong)過(guo)程中(zhong)連(lian)續不(bu)(bu)斷的(de)運行。因此這(zhe)不(bu)(bu)是(shi)(shi)真(zhen)正的(de)五軸(zhou)(zhou)聯動(dong)技(ji)術，3+2軸(zhou)(zhou)的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)心可以(yi)滿(man)足普通加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)心無法完成的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)操(cao)作，但(dan)這(zhe)也并(bing)不(bu)(bu)是(shi)(shi)真(zhen)正的(de)五軸(zhou)(zhou)加(jia)(jia)(jia)工(gong)(gong)(gong)中(zhong)心。

真正的五軸加工中心具備刀點跟隨功能，可以在不改(gai)變(bian)任(ren)何參數的情(qing)況下，確(que)保刀具的切削點和(he)零件表(biao)面接觸，避免造成切削陷坑。整(zheng)個路徑運(yun)動(dong)過(guo)程(cheng)中可對(dui)刀具方向進行優化(hua)，同時進行刀具直線(xian)運(yun)動(dong)。這樣，在整(zheng)個路徑上都可保持(chi)最(zui)佳切削狀態。

五軸(zhou)加工中心(xin)是目(mu)前加工異面體、箱體、復(fu)雜(za)腔體特(te)別(bie)有效的(de)設備。對一個國家的(de)航(hang)空航(hang)天、軍(jun)事科研(yan)、精密器械(xie)、汽車設備、高精醫療設備等領(ling)域(yu)有著舉足(zu)輕重(zhong)的(de)影響力。
