CNC加工方(fang)(fang)式(shi)也是(shi)(shi)會涉(she)及到壓鑄工(gong)藝在工(gong)業領域里，精密零件(jian)分為很多(duo)種。由于(yu)每個(ge)行業所涉(she)及的(de)(de)(de)(de)技術都是(shi)(shi)不(bu)同(tong)的(de)(de)(de)(de)，因(yin)此所采用(yong)(yong)和(he)使(shi)用(yong)(yong)的(de)(de)(de)(de)零件(jian)也是(shi)(shi)截然不(bu)同(tong)的(de)(de)(de)(de)。由于(yu)零件(jian)的(de)(de)(de)(de)造型不(bu)同(tong)，很多(duo)情況(kuang)下它(ta)們都要通過各種加(jia)工(gong)方(fang)(fang)式(shi)來加(jia)強(qiang)它(ta)的(de)(de)(de)(de)質(zhi)量和(he)相關(guan)的(de)(de)(de)(de)屬性(xing)功能(neng)。現如今的(de)(de)(de)(de)數控(kong)加(jia)工(gong)方(fang)(fang)式(shi)已(yi)經(jing)延伸(shen)到各種制造領域，其中CNC加(jia)工(gong)方(fang)(fang)式(shi)也是(shi)(shi)一種加(jia)強(qiang)金屬產品的(de)(de)(de)(de)常(chang)用(yong)(yong)手段。隨(sui)著技術的(de)(de)(de)(de)特(te)點不(bu)斷地提升(sheng)，它(ta)的(de)(de)(de)(de)加(jia)工(gong)質(zhi)量也逐漸(jian)地升(sheng)級和(he)改造。

CNC加(jia)(jia)工(gong)(gong)中壓(ya)(ya)鑄(zhu)工(gong)(gong)藝(yi)就是(shi)利用(yong)機器、模(mo)具(ju)和(he)合金(jin)等三大要(yao)素，將壓(ya)(ya)力、速(su)(su)度(du)及時間(jian)(jian)統一(yi)的過程(cheng)(cheng)。用(yong)于金(jin)屬(shu)熱加(jia)(jia)工(gong)(gong)，壓(ya)(ya)力的存在(zai)是(shi)壓(ya)(ya)鑄(zhu)工(gong)(gong)藝(yi)區別其他鑄(zhu)造(zao)(zao)方(fang)法(fa)的主要(yao)特點.。CNC加(jia)(jia)工(gong)(gong)的壓(ya)(ya)力鑄(zhu)造(zao)(zao)是(shi)近代(dai)金(jin)屬(shu)加(jia)(jia)工(gong)(gong)工(gong)(gong)藝(yi)中發展較快的一(yi)種少無切削(xue)的特種鑄(zhu)造(zao)(zao)方(fang)法(fa)。它是(shi)將熔(rong)融金(jin)屬(shu)在(zai)高(gao)(gao)(gao)壓(ya)(ya)高(gao)(gao)(gao)速(su)(su)下充填鑄(zhu)型(xing)，并在(zai)高(gao)(gao)(gao)壓(ya)(ya)下結晶凝固形成鑄(zhu)件的過程(cheng)(cheng)。高(gao)(gao)(gao)壓(ya)(ya)高(gao)(gao)(gao)速(su)(su)是(shi)壓(ya)(ya)力鑄(zhu)造(zao)(zao)的主要(yao)特征。常用(yong)的壓(ya)(ya)力為(wei)數(shu)十兆(zhao)帕(pa)，填充速(su)(su)度(du)（內澆口速(su)(su)度(du)）約(yue)為(wei)16～80米/秒(miao)，金(jin)屬(shu)液填充模(mo)具(ju)型(xing)腔的時間(jian)(jian)極短，約(yue)為(wei)0.01～0.2秒(miao)。

CNC加工(gong)(gong)中壓(ya)(ya)(ya)(ya)鑄工(gong)(gong)藝是(shi)將壓(ya)(ya)(ya)(ya)鑄機、壓(ya)(ya)(ya)(ya)鑄模和(he)(he)合(he)金(jin)(jin)三大要(yao)素(su)有(you)機地(di)組合(he)而加以綜合(he)運用的過(guo)(guo)程(cheng)。而壓(ya)(ya)(ya)(ya)鑄時(shi)金(jin)(jin)屬(shu)按填充型腔的過(guo)(guo)程(cheng)，是(shi)將壓(ya)(ya)(ya)(ya)力(li)(li)、速(su)度、溫(wen)度以及時(shi)間(jian)(jian)等工(gong)(gong)藝因(yin)(yin)素(su)得到(dao)統(tong)一(yi)的過(guo)(guo)程(cheng)。同時(shi)，這(zhe)(zhe)些工(gong)(gong)藝因(yin)(yin)素(su)又相(xiang)(xiang)互(hu)影響(xiang)，相(xiang)(xiang)互(hu)制(zhi)約，并(bing)且相(xiang)(xiang)輔相(xiang)(xiang)成。只有(you)正確選擇和(he)(he)調(diao)整這(zhe)(zhe)些因(yin)(yin)素(su)，使之協(xie)調(diao)一(yi)致，才能(neng)獲得預期的結(jie)果(guo)。因(yin)(yin)此，在CNC加工(gong)(gong)壓(ya)(ya)(ya)(ya)鑄過(guo)(guo)程(cheng)中不僅(jin)要(yao)重(zhong)視鑄件(jian)結(jie)構的工(gong)(gong)藝性，壓(ya)(ya)(ya)(ya)鑄模的先進(jin)性，壓(ya)(ya)(ya)(ya)鑄機性能(neng)和(he)(he)結(jie)構優良性，壓(ya)(ya)(ya)(ya)鑄合(he)金(jin)(jin)選用的適應(ying)性和(he)(he)熔(rong)煉工(gong)(gong)藝的規范性；更應(ying)重(zhong)視壓(ya)(ya)(ya)(ya)力(li)(li)、溫(wen)度和(he)(he)時(shi)間(jian)(jian)等工(gong)(gong)藝參數對鑄件(jian)質量(liang)的重(zhong)要(yao)作(zuo)用。在壓(ya)(ya)(ya)(ya)鑄過(guo)(guo)程(cheng)中應(ying)重(zhong)視對這(zhe)(zhe)些參數進(jin)行(xing)有(you)效(xiao)的控制(zhi)。
