机加(jia)工(gong)(gong)(gong)加(jia)工(gong)(gong)(gong)制作工(gong)(gong)(gong)艺 大抵可划分为不爱了后(hou)(hou)了工(gong)(gong)(gong)艺和挤压(ya)(ya)成(cheng)型工(gong)(gong)(gong)艺（又(you)分坎坷(ke)不平、拉深、挤压(ya)(ya)成(ch🍒eng)型）两个(ge)类。不爱了后(hou)(hou)了工(gong)(gong)(gong)艺是(shi)在机加(jia)工(gong)(gong)(gong)的进程中使机加(jia)工(gong)(gong)(gong)件(jian)与(yu)坯(pi)料(liao)沿自(zi)(zi)然的表层线这样不爱了后(hou)(hou)了，并且(qie)机加(jia)工(gong)(gong)(gong)件(jian)不爱了后(hou)(hou)了横断面的品控还是(shi)要(yao)知足自(zi)(zi)然的請(qing)求；挤压(ya)(ya)成(cheng)型工(gong)(gong)(gong)艺是(shi)使机加(jia)工(gong)(gong)(gong)坯(pi)料(liao)不在搅碎的基本前提发放生塑(su)性材料(liao)断裂，并还原成(cheng)成(cheng)所請(qing)求的原材料(liao)外观形状，并且(qie)也应知足尺寸图公役等方位的請(qing)求。
要根据模(mo)具机(ji)加(jia)工时的(de)气温区域(yu)环境有冷模(mo)具机(ji)加(jia)工和(he)热(re)模(mo)具机(ji)加(jia)工两者体例(li)。这在于(yu)于(yu)资源的(de)硬(ying)度(du)、塑性磨(mo)(mo)损、高(🅺gao)度(du)、磨(mo)(mo)损能力和(he)武器也能等，另外(wai)招(zhao)考(kao)虑(lv)资源的(de)默认热(re)处治现象(xiang)和(he♏)终归进行本质。
