鈑金(jin)零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)指用(yong)(yong)金(jin)屬(shu)(shu)(shu)（鋼）板經過模(mo)具沖(chong)壓制(zhi)成的零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)，如車身上的金(jin)屬(shu)(shu)(shu)覆蓋(gai)件(jian)(jian)(jian)和加強零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)。不包括塑(su)料等非(fei)金(jin)屬(shu)(shu)(shu)零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)。鈑金(jin)制(zhi)圖師機械(xie)制(zhi)圖的一(yi)種，一(yi)般先做出(chu)(chu)表面形狀，因鈑金(jin)件(jian)(jian)(jian)厚度是相等的，所以可(ke)不畫出(chu)(chu)厚度，在材(cai)料欄標出(chu)(chu)材(cai)料時表示出(chu)(chu)厚度。機械(xie)制(zhi)圖是一(yi)種制(zhi)圖方法，可(ke)以用(yong)(yong)于表達大多數(shu)零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)，如塑(su)料注塑(su)零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)，橡膠零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)，金(jin)屬(shu)(shu)(shu)機加零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)、鑄造(zao)、鍛造(zao)零(ling)(ling)(ling)(ling)件(jian)(jian)(jian)等。

機械鈑(ban)(ban)(ban)金(jin)結構設(she)計(ji)的工藝性(xing)是指零(ling)件(jian)在沖(chong)切、彎曲(qu)、拉伸加工中的難易(yi)程度。良好的工藝應材(cai)料消(xiao)耗(hao)少，工序數目少，模具結構簡單，使(shi)用(yong)壽命高，產品質量穩定。在一般情況下，對鈑(ban)(ban)(ban)金(jin)件(jian)工藝性(xing)影(ying)響是材(cai)料的性(xing)能(neng)、零(ling)件(jian)的幾(ji)何形狀、尺(chi)寸和精度要求(qiu)。搞鈑(ban)(ban)(ban)金(jin)結構設(she)計(ji)，需要了解(jie)鈑(ban)(ban)(ban)金(jin)的工藝性(xing)。要會工藝分解(jie)，否則，是搞不(bu)好鈑(ban)(ban)(ban)金(jin)結構設(she)計(ji)的。
