鈑金(jin)(jin)零(ling)件(jian)(jian)(jian)指用金(jin)(jin)屬(shu)(shu)（鋼）板經過模具沖壓制(zhi)成的(de)(de)零(ling)件(jian)(jian)(jian)，如(ru)車身(shen)上的(de)(de)金(jin)(jin)屬(shu)(shu)覆蓋(gai)件(jian)(jian)(jian)和加(jia)強零(ling)件(jian)(jian)(jian)。不包括塑料(liao)(liao)等非金(jin)(jin)屬(shu)(shu)零(ling)件(jian)(jian)(jian)。鈑金(jin)(jin)制(zhi)圖(tu)(tu)師機械制(zhi)圖(tu)(tu)的(de)(de)一種，一般先做出(chu)表(biao)面(mian)形狀，因鈑金(jin)(jin)件(jian)(jian)(jian)厚(hou)度(du)是相等的(de)(de)，所(suo)以可不畫出(chu)厚(hou)度(du)，在材(cai)料(liao)(liao)欄標出(chu)材(cai)料(liao)(liao)時表(biao)示出(chu)厚(hou)度(du)。機械制(zhi)圖(tu)(tu)是一種制(zhi)圖(tu)(tu)方法(fa)，可以用于(yu)表(biao)達大多(duo)數零(ling)件(jian)(jian)(jian)，如(ru)塑料(liao)(liao)注(zhu)塑零(ling)件(jian)(jian)(jian)，橡(xiang)膠零(ling)件(jian)(jian)(jian)，金(jin)(jin)屬(shu)(shu)機加(jia)零(ling)件(jian)(jian)(jian)、鑄造、鍛造零(ling)件(jian)(jian)(jian)等。

機械鈑金結構(gou)(gou)設(she)計(ji)的(de)(de)工(gong)(gong)藝性(xing)是指零件在沖(chong)切、彎(wan)曲、拉伸加(jia)工(gong)(gong)中的(de)(de)難易(yi)程度(du)。良(liang)好(hao)的(de)(de)工(gong)(gong)藝應材料(liao)消耗少(shao)，工(gong)(gong)序(xu)數目(mu)少(shao)，模具結構(gou)(gou)簡單，使用(yong)壽命(ming)高(gao)，產品質量穩定。在一般情況下，對鈑金件工(gong)(gong)藝性(xing)影響是材料(liao)的(de)(de)性(xing)能、零件的(de)(de)幾何形狀、尺寸和精度(du)要求。搞鈑金結構(gou)(gou)設(she)計(ji)，需(xu)要了解鈑金的(de)(de)工(gong)(gong)藝性(xing)。要會(hui)工(gong)(gong)藝分(fen)解，否則，是搞不好(hao)鈑金結構(gou)(gou)設(she)計(ji)的(de)(de)。
