模具零件加(jia)工工藝屬機械加(jia)工工藝范疇，是(shi)(shi)指：用(yong)機械加(jia)工的方法改(gai)變毛坯(pi)的形狀、尺寸(cun)、相(xiang)對位置和性質使其成(cheng)為(wei)合格(ge)零件的全過程(cheng)，加(jia)工工藝是(shi)(shi)工人進行(xing)加(jia)工的依據。

加工(gong)(gong)(gong)工(gong)(gong)(gong)藝定義中的(de)(de)(de)(de)(de)(de)關鍵(jian)詞：“機(ji)械(xie)加工(gong)(gong)(gong)的(de)(de)(de)(de)(de)(de)方(fang)法(fa)”，因模具(ju)型(xing)腔加工(gong)(gong)(gong)的(de)(de)(de)(de)(de)(de)特殊性，模具(ju)零件(jian)(jian)加工(gong)(gong)(gong)工(gong)(gong)(gong)藝除(chu)采用(yong)機(ji)械(xie)加工(gong)(gong)(gong)方(fang)法(fa)外，還包(bao)括了電(dian)加工(gong)(gong)(gong)和(he)熱處理(li)。“改(gai)變毛坯尺寸、相對位置和(he)性質”，無論機(ji)械(xie)加工(gong)(gong)(gong)還是電(dian)加工(gong)(gong)(gong)的(de)(de)(de)(de)(de)(de)方(fang)法(fa)，要(yao)達到(dao)使(shi)毛坯成為合格零件(jian)(jian)的(de)(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)(de)，需(xu)要(yao)設備、刀具(ju)、裝夾、輔(fu)具(ju)等硬件(jian)(jian)，需(xu)要(yao)程序、參(can)數等軟件(jian)(jian)。“全過(guo)程”，需(xu)要(yao)不(bu)同(tong)的(de)(de)(de)(de)(de)(de)工(gong)(gong)(gong)序、工(gong)(gong)(gong)步，每個工(gong)(gong)(gong)序的(de)(de)(de)(de)(de)(de)硬件(jian)(jian)和(he)軟件(jian)(jian)不(bu)同(tong)。

從對模具零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)關鍵(jian)詞的(de)分(fen)析，不(bu)(bu)難看出模具零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)是一個(ge)過(guo)程，在這個(ge)過(guo)程中包含了不(bu)(bu)同(tong)的(de)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)，和不(bu)(bu)同(tong)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)的(de)設備、刀(dao)具、裝(zhuang)夾、輔(fu)具、工(gong)(gong)(gong)(gong)(gong)作(zuo)參(can)數的(de)組合。模具零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)設計，就是根據模具零(ling)件(jian)的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)要求，進行的(de)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)劃定(ding)和每(mei)個(ge)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)的(de)硬件(jian)、軟件(jian)組合。

壓鑄模具零件(jian)加(jia)工屬機械加(jia)工范疇特點：復(fu)雜(za)型腔需(xu)要電加(jia)工的組合(he)；可分(fen)類(lei)，但不可完全批量化生產(chan)。幾何體、幾何尺寸變化，看(kan)似單件(jian)生產(chan)，同樣可以實現工序化生產(chan)。

模具(ju)(ju)制造過程(cheng)(cheng)分(fen)為模具(ju)(ju)零(ling)件加工(gong)和模具(ju)(ju)裝配(pei)兩(liang)個部分(fen)，模具(ju)(ju)零(ling)件的(de)加工(gong)結果，直(zhi)接(jie)影響模具(ju)(ju)的(de)裝配(pei)精度(du)、模具(ju)(ju)的(de)使(shi)用性能和壓(ya)鑄(zhu)件的(de)制造精度(du)，模具(ju)(ju)零(ling)件加工(gong)工(gong)藝(yi)設計(ji)是模具(ju)(ju)制造過程(cheng)(cheng)的(de)核心技術(shu)。

加(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)設(she)(she)(she)(she)計(ji)(ji)(ji)的(de)(de)(de)目的(de)(de)(de)，是(shi)要(yao)實現模具(ju)零件(jian)(jian)的(de)(de)(de)設(she)(she)(she)(she)計(ji)(ji)(ji)要(yao)求，模具(ju)零件(jian)(jian)的(de)(de)(de)設(she)(she)(she)(she)計(ji)(ji)(ji)要(yao)求輸出(chu)是(shi)模具(ju)零件(jian)(jian)的(de)(de)(de)二維圖紙，在模具(ju)設(she)(she)(she)(she)計(ji)(ji)(ji)輸出(chu)中，三(san)維造型使用于(yu)描述模具(ju)結(jie)構和作(zuo)為數控加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)依據(ju)，二維圖紙是(shi)用于(yu)零件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)設(she)(she)(she)(she)計(ji)(ji)(ji)的(de)(de)(de)依據(ju)。
