為適應全(quan)球制造行業(ye)的(de)需求，數(shu)控(kong)系(xi)(xi)統網絡(luo)化(hua)(hua)(hua)是(shi)必然發展方向(xiang)(xiang)。網絡(luo)可(ke)以把(ba)世界(jie)上的(de)資源(yuan)(yuan)進(jin)行最優配置，數(shu)控(kong)系(xi)(xi)統的(de)網絡(luo)化(hua)(hua)(hua)最先是(shi)企業(ye)內部的(de)數(shu)控(kong)系(xi)(xi)統網絡(luo)化(hua)(hua)(hua)，數(shu)控(kong)之間通(tong)過企業(ye)內部局域網進(jin)行相互通(tong)信，然后再經由因特網通(tong)向(xiang)(xiang)企業(ye)外部，這就是(shi)所謂的(de)Inter-net/Internet技術(shu)。這樣(yang)就把(ba)世界(jie)上幾(ji)乎所有的(de)數(shu)控(kong)系(xi)(xi)統聯系(xi)(xi)起(qi)來，促成了(le)世界(jie)資源(yuan)(yuan)的(de)優化(hua)(hua)(hua)配置。
隨著(zhu)加工(gong)(gong)效率的(de)提高，人們對物質需求的(de)大(da)量增(zeng)加，數(shu)控系(xi)統工(gong)(gong)作(zuo)時(shi)(shi)間(jian)(jian)越(yue)來(lai)越(yue)長，這(zhe)(zhe)就(jiu)必(bi)然需要(yao)數(shu)控系(xi)統在長時(shi)(shi)間(jian)(jian)內能夠(gou)保證其(qi)穩定性(xing)(xing)，加工(gong)(gong)的(de)產品才(cai)能合(he)格。這(zhe)(zhe)就(jiu)對數(shu)控系(xi)統提出(chu)了高可靠(kao)性(xing)(xing)的(de)要(yao)求，對于(yu)每天工(gong)(gong)作(zuo)兩班的(de)無人工(gong)(gong)廠(chang)而言，如(ru)果要(yao)求在16小時(shi)(shi)內連續正常工(gong)(gong)作(zuo)、無故障率達(da)99%以上，則數(shu)控車床(chuang)的(de)平均無故障運(yun)行(xing)時(shi)(shi)間(jian)(jian)就(jiu)必(bi)須大(da)于(yu)3000小時(shi)(shi)。這(zhe)(zhe)就(jiu)要(yao)求數(shu)控配置(zhi)、主軸(zhou)及伺(si)服驅動等的(de)平均無故障運(yun)行(xing)時(shi)(shi)間(jian)(jian)必(bi)須在10萬小時(shi)(shi)以上。日本FANUC系(xi)統早在20世紀80年代末(mo)就(jiu)能夠(gou)達(da)到這(zhe)(zhe)種高可靠(kao)性(xing)(xing)的(de)要(yao)求，現(xian)在正向(xiang)更(geng)高可靠(kao)性(xing)(xing)方向(xiang)發展。
在生產過程(cheng)(cheng)(cheng)中，往(wang)往(wang)發(fa)現(xian)(xian)這(zhe)樣的(de)(de)(de)(de)現(xian)(xian)象：一個(ge)零(ling)件(jian)(jian)本身被刀(dao)具加工(gong)的(de)(de)(de)(de)時(shi)間(jian)(jian)不(bu)長，而工(gong)人裝夾(jia)的(de)(de)(de)(de)時(shi)間(jian)(jian)有(you)時(shi)候大(da)于加工(gong)時(shi)間(jian)(jian)。這(zhe)種(zhong)在零(ling)件(jian)(jian)加工(gong)過程(cheng)(cheng)(cheng)中大(da)量(liang)的(de)(de)(de)(de)無功(gong)(gong)效(xiao)時(shi)間(jian)(jian)對于生產來說是不(bu)利的(de)(de)(de)(de)，所(suo)以現(xian)(xian)代自(zi)(zi)動化高的(de)(de)(de)(de)工(gong)廠一般的(de)(de)(de)(de)數(shu)控車床配有(you)工(gong)件(jian)(jian)搬運、自(zi)(zi)動上下料、自(zi)(zi)動換刀(dao)等系(xi)(xi)統(tong)，可以盡(jin)可能(neng)降低(di)這(zhe)些無功(gong)(gong)效(xiao)時(shi)間(jian)(jian)。這(zhe)種(zhong)能(neng)夠把多(duo)種(zhong)不(bu)同功(gong)(gong)能(neng)的(de)(de)(de)(de)系(xi)(xi)統(tong)整合在一臺數(shu)控車床的(de)(de)(de)(de)過程(cheng)(cheng)(cheng)就是數(shu)控系(xi)(xi)統(tong)的(de)(de)(de)(de)負荷化。
