机(ji)加工(gong)(gong)模(mo)具(ju)(ju)加工(gong)(go🌱ng)工(gong)(gong)艺大抵可划分(fen)为即(ji)使(shi)被断(duan)联(lian)(lian)工(gong)(gong)作(zuo)和(he)定(ding)型工(gong)(gong)作(zuo)（又分(fen)婉(wan)延、拉(la)深、定(ding)型）两个类。即(ji)使(shi)被断(duan)联(lian)(lian)工ꦜ(gong)(gong)作(zuo)是在机(ji)加工(gong)(gong)模(mo)具(ju)(ju)阶段中使(shi)机(ji)加工(gong)(gong)模(mo)具(ju)(ju)件与坯料沿肯定(ding)的接触面线我们之间即(ji)使(shi)被断(duan)联(lian)(lian)，一起(qi)(qi)机(ji)加工(gong)(gong)模(mo)具(ju)(ju)件即(ji)使(shi)被断(duan)联(lian)(lian)坡(po)面的品质保证也需知足肯定(ding)的恳求；定(ding)型工(gong)(gong)作(zuo)是使(shi)机(ji)加工(gong)(gong)模(mo)具(ju)(ju)坯料都不碎(sui)粉的情况发(fa)放生蠕变压扁，并变为成所恳求的原(yuan)料外表，一起(qi)(qi)也应知足长度公役等几(ji)个方面的恳求。
依(yi)据(ju)机加工(gong)时的(de)平均(jun)温度场景有冷机加工(gong)和(he)热机加工(go𓄧ng)这(zhei)两种体(ti)例。这(zhei)考量(liang)于(yu)相关(guan)資料(liao)的(de)硬度、塑性和(he)变(bian)形、机的(de)薄(bo)厚、和(he)变(bian)形平均(jun)水平和(he)辅助装备这(zhei)样才(cai)能等，同(tong)一招考虑(lv)相关(guan)資♑料(liao)的(de)原使热处理状态和(he)终究会采用前题。
