鈑(ban)金零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)指用金屬(shu)（鋼）板經過模具沖壓制(zhi)(zhi)成(cheng)的(de)(de)(de)零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)，如(ru)車身上(shang)的(de)(de)(de)金屬(shu)覆(fu)蓋(gai)件(jian)(jian)(jian)(jian)和加(jia)強零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)。不包括塑(su)料(liao)等(deng)非(fei)金屬(shu)零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)。鈑(ban)金制(zhi)(zhi)圖師(shi)機(ji)械制(zhi)(zhi)圖的(de)(de)(de)一種(zhong)，一般先做(zuo)出表(biao)面形狀，因(yin)鈑(ban)金件(jian)(jian)(jian)(jian)厚(hou)度(du)(du)是相等(deng)的(de)(de)(de)，所以可不畫出厚(hou)度(du)(du)，在材(cai)(cai)料(liao)欄標(biao)出材(cai)(cai)料(liao)時表(biao)示出厚(hou)度(du)(du)。機(ji)械制(zhi)(zhi)圖是一種(zhong)制(zhi)(zhi)圖方法，可以用于(yu)表(biao)達(da)大多數零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)，如(ru)塑(su)料(liao)注(zhu)塑(su)零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)，橡膠零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)，金屬(shu)機(ji)加(jia)零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)、鑄造(zao)、鍛造(zao)零(ling)(ling)(ling)(ling)(ling)件(jian)(jian)(jian)(jian)等(deng)。

機械鈑(ban)金(jin)結構(gou)設計(ji)的工(gong)(gong)(gong)(gong)藝(yi)性(xing)(xing)是指零件在(zai)沖切、彎曲、拉(la)伸(shen)加工(gong)(gong)(gong)(gong)中的難易程度(du)。良好的工(gong)(gong)(gong)(gong)藝(yi)應材(cai)(cai)料消耗少，工(gong)(gong)(gong)(gong)序數目少，模具結構(gou)簡單(dan)，使用壽命(ming)高，產品質(zhi)量穩定。在(zai)一般情況下(xia)，對鈑(ban)金(jin)件工(gong)(gong)(gong)(gong)藝(yi)性(xing)(xing)影響是材(cai)(cai)料的性(xing)(xing)能(neng)、零件的幾何(he)形(xing)狀、尺寸和精(jing)度(du)要求。搞鈑(ban)金(jin)結構(gou)設計(ji)，需(xu)要了(le)解鈑(ban)金(jin)的工(gong)(gong)(gong)(gong)藝(yi)性(xing)(xing)。要會(hui)工(gong)(gong)(gong)(gong)藝(yi)分解，否則，是搞不好鈑(ban)金(jin)結構(gou)設計(ji)的。
