机加(jia)(jia)工(gong)(gong)(gong)模(mo)(mo)(mo)具(ju)(ju)工(gong)(gong)(gong)艺设计大抵可划分为断(duan)联(lian)(lian)工(gong)(gong)(gong)步(bu)和塑(su🌸)压工(gong)(gong)(gong)步(bu)（又分跌宕、拉深、塑(su)压）2小类。断(duan)联(lian)(lian)工(gong)(gong)(gong)步(bu)是(shi)在(zai)机加(jia)(jia)工(gong)(gong)(gong)模(mo)(mo)(mo)具(ju)(ju)流程(cheng)中使机加(jia)(jia)工(gong)(gong)(gong)模(mo)(mo)(mo)具(ju)(ju)件与坯料沿必(bi)定(ding)(ding)的(de)表层线另一半断(duan)联(lian)(lian)，同一时间机加(jia)(jia)工(gong)(gong)(gong)模(mo)(mo)(mo)具(ju)(ju)件断(duan)联(lian)(lian)纵断(duan)面(mian)的(de)品性也得知(zhi)足必(bi)定(ding)(ding)的(de)恳(ken)求(qiu)(qiu)；塑(su)压工(gong)(gong)(gong)步(bu)是(shi)使机加(jia)(jia)工(gong)(gong)(gong)模(mo)(mo)(mo)具(ju)(ju)坯料在(zai)确(que)定(ding)(ding)不破碎的(de)条(tiao)件颁发生(sheng)塑(su)性材料变形几率，并转换(huan)成(cheng)所恳(ken)求(qiu)(qiu)的(de)制成(cheng)品外(wai)观(guan)简约时尚，同一时间也应知(zhi)足尺寸(cu⛎n)大小公(gong)役等因素的(de)恳(ken)求(qiu)(qiu)。
据五金机(ji)(ji)加(jia)工(gong)时的温度(du)因素区域(yu)环境有冷五金机(ji)(ji)加(jia)工(gong)和(he)(he)(he)热(re)五金机(ji)(ji)加(jia)工(gong)每(mei)种体例。这衡量于材(cai)料的屈(qu)服(fu)强度(du)、塑性材(cai)料、料厚(hou)、变型情(qing)况和(he)(he)(he)武器才行等，同時招考虑材(cai)料的原状热(re)救治(zhi)的情(qing)况和(he)(he)(he)既然(ran)借助(zhu)情(q▨ing)况。
