零件(jian)(jian)(jian)金屬板(ban)材加(jia)(jia)工(gong)就叫(jiao)鈑金加(jia)(jia)工(gong)。具體譬如利用(yong)板(ban)材制(zhi)作煙囪(cong)、鐵(tie)桶、油箱(xiang)油壺、通(tong)風管道、彎頭大(da)小頭、天圓地方、漏(lou)斗(dou)形(xing)等(deng)，主(zhu)要(yao)工(gong)序有(you)剪(jian)切、折彎扣邊(bian)、彎曲(qu)(qu)成型、焊接、鉚接等(deng)，需要(yao)一定幾(ji)何知識。鈑金件(jian)(jian)(jian)就是薄(bo)板(ban)五(wu)金件(jian)(jian)(jian)，也(ye)就是可(ke)以通(tong)過(guo)沖壓，彎曲(qu)(qu)，拉伸等(deng)手段來加(jia)(jia)工(gong)的零件(jian)(jian)(jian)，一個大(da)體的定義(yi)就是在加(jia)(jia)工(gong)過(guo)程中厚度不變的零件(jian)(jian)(jian)。相對應的是鑄造件(jian)(jian)(jian)，鍛壓件(jian)(jian)(jian)，機械加(jia)(jia)工(gong)零件(jian)(jian)(jian)等(deng)。
