為適(shi)應(ying)全球制造行業(ye)的需求，數(shu)控系統(tong)網絡(luo)化(hua)是必然發展(zhan)方向(xiang)。網絡(luo)可以(yi)把(ba)世(shi)界上的資(zi)源進行最(zui)優(you)配置，數(shu)控系統(tong)的網絡(luo)化(hua)最(zui)先(xian)是企(qi)業(ye)內部(bu)(bu)(bu)的數(shu)控系統(tong)網絡(luo)化(hua)，數(shu)控之間通(tong)過企(qi)業(ye)內部(bu)(bu)(bu)局(ju)域網進行相互通(tong)信，然后(hou)再經由因特網通(tong)向(xiang)企(qi)業(ye)外部(bu)(bu)(bu)，這就是所謂的Inter-net/Internet技(ji)術。這樣(yang)就把(ba)世(shi)界上幾乎所有的數(shu)控系統(tong)聯系起來(lai)，促成了世(shi)界資(zi)源的優(you)化(hua)配置。
隨著加工(gong)(gong)(gong)效率的提高，人們對(dui)物質(zhi)需求(qiu)(qiu)的大量增加，數控(kong)(kong)系(xi)統工(gong)(gong)(gong)作(zuo)時間越來越長，這(zhe)就必然需要數控(kong)(kong)系(xi)統在(zai)長時間內能(neng)夠保(bao)證其穩定性，加工(gong)(gong)(gong)的產品才能(neng)合格。這(zhe)就對(dui)數控(kong)(kong)系(xi)統提出了高可靠(kao)性的要求(qiu)(qiu)，對(dui)于每(mei)天工(gong)(gong)(gong)作(zuo)兩(liang)班的無(wu)人工(gong)(gong)(gong)廠而言，如果要求(qiu)(qiu)在(zai)16小(xiao)(xiao)時內連續正常工(gong)(gong)(gong)作(zuo)、無(wu)故(gu)障率達99%以上，則(ze)數控(kong)(kong)車床的平(ping)(ping)均(jun)無(wu)故(gu)障運行(xing)時間就必須大于3000小(xiao)(xiao)時。這(zhe)就要求(qiu)(qiu)數控(kong)(kong)配置、主軸及伺服(fu)驅動等的平(ping)(ping)均(jun)無(wu)故(gu)障運行(xing)時間必須在(zai)10萬小(xiao)(xiao)時以上。日本(ben)FANUC系(xi)統早在(zai)20世紀80年代末就能(neng)夠達到(dao)這(zhe)種(zhong)高可靠(kao)性的要求(qiu)(qiu)，現在(zai)正向(xiang)更高可靠(kao)性方向(xiang)發展。
在(zai)生產過(guo)程中，往(wang)往(wang)發現這(zhe)樣的(de)(de)(de)現象：一(yi)個零(ling)件(jian)本身被刀具加工(gong)(gong)的(de)(de)(de)時間(jian)不長，而工(gong)(gong)人(ren)裝夾的(de)(de)(de)時間(jian)有時候大于加工(gong)(gong)時間(jian)。這(zhe)種(zhong)在(zai)零(ling)件(jian)加工(gong)(gong)過(guo)程中大量(liang)的(de)(de)(de)無功(gong)(gong)效時間(jian)對于生產來說是(shi)不利(li)的(de)(de)(de)，所以(yi)現代自(zi)動(dong)化高的(de)(de)(de)工(gong)(gong)廠一(yi)般(ban)的(de)(de)(de)數(shu)控(kong)車床配(pei)有工(gong)(gong)件(jian)搬運(yun)、自(zi)動(dong)上下(xia)料、自(zi)動(dong)換刀等系(xi)統，可(ke)以(yi)盡可(ke)能(neng)降(jiang)低這(zhe)些無功(gong)(gong)效時間(jian)。這(zhe)種(zhong)能(neng)夠(gou)把多種(zhong)不同功(gong)(gong)能(neng)的(de)(de)(de)系(xi)統整(zheng)合在(zai)一(yi)臺數(shu)控(kong)車床的(de)(de)(de)過(guo)程就是(shi)數(shu)控(kong)系(xi)統的(de)(de)(de)負荷化。
