、確定零件在機床工作台上的最佳位置 在臥式加工中心上加工零件時，由於要進行多工位加工，就要考慮零件（包括夾具）在(zai)機(ji)床(chuang)工(gong)作(zuo)台(tai)上(shang)的(de)最(zui)佳(jia)位(wei)置(zhi)，該(gai)位(wei)置(zhi)是(shi)在(zai)技(ji)術(shu)準(zhun)備(bei)過(guo)程(cheng)中(zhong)考(kao)慮(lv)機(ji)床(chuang)行(xing)程(cheng)，各(ge)種(zhong)幹(gan)涉(she)情(qing)況(kuang)
，優(you)化(hua)匹(pi)配(pei)各(ge)部(bu)位(wei)刀(dao)具(ju)長(chang)度(du)而(er)確(que)定(ding)的(de)。如(ru)果(guo)考(kao)慮(lv)不(bu)周(zhou)
，將(jiang)會(hui)造(zao)成(cheng)機(ji)床(chuang)超(chao)程(cheng)，更(geng)換(huan)刀(dao)具(ju)
，影(ying)響(xiang)加(jia)工(gong)精(jing)度(du)或(huo)重(zhong)新(xin)進(jin)入(ru)試(shi)切(qie)階(jie)段(duan)而(er)造(zao)成(cheng)浪(lang)廢(fei)工(gong)時(shi)等(deng)不(bu)良(liang)後(hou)果(guo)
，也(ye)增(zeng)大(da)了(le)出(chu)現(xian)廢(fei)品(pin)的(de)可(ke)能(neng)性(xing)。 加工中心具有的自動換刀（ATC）功能決定了其最大的弱點為刀具懸臂式加工，在加工過程中不能使用鏜模
