冷(leng)(leng)冷(leng)(leng)机(ji)(ji)加(jia)(jia)(jia)工(gong)(gong)加(jia)(jia)(jia)工(gong)(gong)道步(bu)(bu)骤大(da)抵可可分成断(duan)联(lian)道步(bu)(bu)骤和定型(xing)道步(bu)(bu)骤（又(you)分婉延、拉深、定型(xing)）两个类。断(duan)联(lian)道步(bu)(bu)骤是在(zai)冷(leng)(leng)冷(leng)(leng)机(ji)(ji)加(jia)(jia)(jia)工(gong)(gong)加(jia)(jia)(jia)工(gong)(gong)的(de)进(jin)程中(zhong)使冷(leng)(leng)冷(leng)(leng)机(ji)(ji)加(jia)(jia)(jia)工(gong)(gong)加(jia)(jia)(jia)工(gong)(gong)件(jian)与坯料(liao)沿必需的(de)外(wai)表(biao)线(xian)我们之间断(duan)联(lian)，同時(shi)冷(leng)(leng)冷(leng)(leng)机(ji)(ji)加(jia)(jia)(jia)工(gong)(gong)加(jia)(jia)(jia)工(gong)(gong)件(jian)断(duan)联(lian)横截面的(de)产品质量也是要知(zhi)足必需的(de)明(ming)确提(ti)出；定型(xing)道步(bu)(bu)骤是使冷(leng)(leng)冷(leng)(leng)机(ji)(ji)加(jia)(jia)(jia)工(gong)(gong)加(jia)(jia)(jia)工(gong)(gong)坯料(liao)是不粉粹的(de)首先下发(fa)文件(jian)生塑形变化，并导出成所(suo)明(ming)💜确提(ti)出的(de)机(ji)(ji)器设备外(wai)貌，同時(shi)也应知(zhi)足长度公役(yi)等角(jiao)度的(de)明(ming)确提(ti)出。
要根(gen)据机(ji)加工时的摄(she)氏(shi)度(du)情况有冷机(ji)加工和(he)热(re)机(ji)加工哪几种体(ti)例。这决定于于材料的硬度(du)、塑型、板材的厚(hou)度(du)、形变情况和(he)辅助装备(bei)就能等，同时招考虑材料的原(yuan)有热(re)救治情況和(he)爱到最后回收(shou𝐆)利用基本原(yuan)则。
