CNC加工方(fang)(fang)式(shi)(shi)(shi)也是會涉及到壓(ya)鑄工(gong)(gong)藝在工(gong)(gong)業領(ling)域(yu)里，精密零件(jian)分(fen)為(wei)很多(duo)種。由(you)于每(mei)個行(xing)業所(suo)涉及的(de)技術(shu)都是不(bu)同的(de)，因此所(suo)采用(yong)(yong)和使用(yong)(yong)的(de)零件(jian)也是截然不(bu)同的(de)。由(you)于零件(jian)的(de)造(zao)型不(bu)同，很多(duo)情(qing)況下它們(men)都要通(tong)過各種加工(gong)(gong)方(fang)(fang)式(shi)(shi)(shi)來加強(qiang)它的(de)質(zhi)(zhi)量和相關的(de)屬性功能。現如今的(de)數控加工(gong)(gong)方(fang)(fang)式(shi)(shi)(shi)已(yi)經延伸到各種制(zhi)造(zao)領(ling)域(yu)，其(qi)中(zhong)CNC加工(gong)(gong)方(fang)(fang)式(shi)(shi)(shi)也是一(yi)種加強(qiang)金屬產品的(de)常用(yong)(yong)手段(duan)。隨(sui)著(zhu)技術(shu)的(de)特點不(bu)斷地提升(sheng)，它的(de)加工(gong)(gong)質(zhi)(zhi)量也逐漸地升(sheng)級和改造(zao)。

CNC加工(gong)(gong)(gong)(gong)中(zhong)壓(ya)(ya)(ya)鑄工(gong)(gong)(gong)(gong)藝就是(shi)利用(yong)(yong)機器(qi)、模具(ju)和合金等(deng)三大要素(su)，將壓(ya)(ya)(ya)力(li)、速(su)度(du)及時間(jian)統一的(de)(de)(de)過(guo)(guo)程。用(yong)(yong)于金屬(shu)熱加工(gong)(gong)(gong)(gong)，壓(ya)(ya)(ya)力(li)的(de)(de)(de)存(cun)在是(shi)壓(ya)(ya)(ya)鑄工(gong)(gong)(gong)(gong)藝區別其他(ta)鑄造方(fang)法的(de)(de)(de)主要特(te)點.。CNC加工(gong)(gong)(gong)(gong)的(de)(de)(de)壓(ya)(ya)(ya)力(li)鑄造是(shi)近(jin)代金屬(shu)加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝中(zhong)發展(zhan)較快的(de)(de)(de)一種(zhong)少無(wu)切(qie)削的(de)(de)(de)特(te)種(zhong)鑄造方(fang)法。它是(shi)將熔(rong)融金屬(shu)在高(gao)壓(ya)(ya)(ya)高(gao)速(su)下(xia)充填(tian)鑄型，并在高(gao)壓(ya)(ya)(ya)下(xia)結晶凝固(gu)形(xing)成鑄件的(de)(de)(de)過(guo)(guo)程。高(gao)壓(ya)(ya)(ya)高(gao)速(su)是(shi)壓(ya)(ya)(ya)力(li)鑄造的(de)(de)(de)主要特(te)征。常用(yong)(yong)的(de)(de)(de)壓(ya)(ya)(ya)力(li)為數十兆帕，填(tian)充速(su)度(du)（內(nei)澆(jiao)口速(su)度(du)）約(yue)為16～80米/秒，金屬(shu)液(ye)填(tian)充模具(ju)型腔的(de)(de)(de)時間(jian)極短，約(yue)為0.01～0.2秒。

CNC加工(gong)(gong)中壓(ya)(ya)鑄(zhu)(zhu)工(gong)(gong)藝是將壓(ya)(ya)鑄(zhu)(zhu)機、壓(ya)(ya)鑄(zhu)(zhu)模(mo)和(he)(he)合(he)(he)金(jin)三大要素(su)(su)有機地組合(he)(he)而(er)加以綜(zong)合(he)(he)運用(yong)的(de)(de)(de)過(guo)程(cheng)(cheng)。而(er)壓(ya)(ya)鑄(zhu)(zhu)時金(jin)屬按填充型腔的(de)(de)(de)過(guo)程(cheng)(cheng)，是將壓(ya)(ya)力、速(su)度(du)、溫度(du)以及(ji)時間(jian)等(deng)工(gong)(gong)藝因素(su)(su)得到統(tong)一的(de)(de)(de)過(guo)程(cheng)(cheng)。同時，這(zhe)些(xie)(xie)工(gong)(gong)藝因素(su)(su)又相互(hu)影響，相互(hu)制約，并且相輔相成。只有正確(que)選(xuan)擇和(he)(he)調(diao)整這(zhe)些(xie)(xie)因素(su)(su)，使之協調(diao)一致，才能獲(huo)得預期的(de)(de)(de)結果。因此，在CNC加工(gong)(gong)壓(ya)(ya)鑄(zhu)(zhu)過(guo)程(cheng)(cheng)中不(bu)僅要重視(shi)(shi)鑄(zhu)(zhu)件結構的(de)(de)(de)工(gong)(gong)藝性(xing)(xing)，壓(ya)(ya)鑄(zhu)(zhu)模(mo)的(de)(de)(de)先進性(xing)(xing)，壓(ya)(ya)鑄(zhu)(zhu)機性(xing)(xing)能和(he)(he)結構優良性(xing)(xing)，壓(ya)(ya)鑄(zhu)(zhu)合(he)(he)金(jin)選(xuan)用(yong)的(de)(de)(de)適應性(xing)(xing)和(he)(he)熔煉(lian)工(gong)(gong)藝的(de)(de)(de)規范性(xing)(xing)；更應重視(shi)(shi)壓(ya)(ya)力、溫度(du)和(he)(he)時間(jian)等(deng)工(gong)(gong)藝參數對(dui)(dui)鑄(zhu)(zhu)件質量的(de)(de)(de)重要作(zuo)用(yong)。在壓(ya)(ya)鑄(zhu)(zhu)過(guo)程(cheng)(cheng)中應重視(shi)(shi)對(dui)(dui)這(zhe)些(xie)(xie)參數進行(xing)有效的(de)(de)(de)控(kong)制。
