机(ji)械加(jia)工(gong)(gong)方法和适(shi)用范围应(ying)该怎么(me)选择呢？铣(xian)(xian)(xian)(xian)削(xue)(xue)加(jia)工(gong)(gong)：（1）顺铣(xian)(xian)(xian)(xian)：铣(xian)(xian)(xian)(xian)削(xue)(xue)力的(de)水平分力与(yu)工(gong)(gong)件(jian)(jian)(jian)的(de)进(jin)(jin)给方向相同(tong)，工(gong)(gong)件(jian)(jian)(jian)台进(jin)(jin)给丝(si)杠与(yu)固定螺母之间一(yi)般有间隙存(cun)在，因此切(qie)(qie)削(xue)(xue)力容易引(yin)起(qi)工(gong)(gong)件(jian)(jian)(jian)和工(gong)(gong)作(zuo)台一(yi)起(qi)向前窜动(dong)，使进(jin)(jin)给量突然增(zeng)大，引(yin)起(qi)打刀(dao)。在铣(xian)(xian)(xian)(xian)削(xue)(xue)铸件(jian)(jian)(jian)或锻(duan)件(jian)(jian)(jian)等表面(mian)(mian)有硬度(du)的(de)工(gong)(gong)件(jian)(jian)(jian)时，顺铣(xian)(xian)(xian)(xian)刀(dao)齿(chi)首先接(jie)触工(gong)(gong)件(jian)(jian)(jian)硬皮，加(jia)剧了铣(xian)(xian)(xian)(xian)刀(dao)的(de)磨损。（2）逆(ni)(ni)铣(xian)(xian)(xian)(xian)：可以避免顺铣(xian)(xian)(xian)(xian)时发生的(de)窜动(dong)现象。逆(ni)(ni)铣(xian)(xian)(xian)(xian)时，切(qie)(qie)削(xue)(xue)厚(hou)度(du)从零(ling)开始逐渐(jian)增(zeng)大，因而(er)刀(dao)刃开始经历(li)了一(yi)段在切(qie)(qie)削(xue)(xue)硬化的(de)已加(jia)工(gong)(gong)表面(mian)(mian)上(shang)挤压(ya)滑行的(de)阶(jie)段，加(jia)速了刀(dao)具(ju)的(de)磨损。同(tong)时，逆(ni)(ni)铣(xian)(xian)(xian)(xian)时，铣(xian)(xian)(xian)(xian)削(xue)(xue)力将工(gong)(gong)件(jian)(jian)(jian)上(shang)抬，易引(yin)起(qi)振动(dong)，这是逆(ni)(ni)铣(xian)(xian)(xian)(xian)的(de)不利之处。适(shi)用范围：铣(xian)(xian)(xian)(xian)平面(mian)(mian)、铣(xian)(xian)(xian)(xian)台阶(jie)、铣(xian)(xian)(xian)(xian)沟槽、铣(xian)(xian)(xian)(xian)成形(xing)面(mian)(mian)、铣(xian)(xian)(xian)(xian)螺旋槽、铣(xian)(xian)(xian)(xian)齿(chi)轮、切(qie)(qie)断(duan)杭州五(wu)金配件(jian)(jian)(jian)机(ji)械加(jia)工(gong)(gong)哪家(jia)好(hao)机(ji)械加(jia)工(gong)(gong)零(ling)件(jian)(jian)(jian)表面(mian)(mian)质量的(de)控制注意事(shi)项：对于超精密切(qie)(qie)削(xue)(xue)和低粗糙度(du)工(gong)(gong)件(jian)(jian)(jian)的(de)磨削(xue)(xue)加(jia)工(gong)(gong)。
