數(shu)控加工(gong)(gong)(gong)知識在(zai)(zai)打不銹鋼中(zhong)(zhong)心眼(yan)，或者打不銹鋼眼(yan)的(de)時候(hou)鉆(zhan)頭或者中(zhong)(zhong)心鉆(zhan)中(zhong)(zhong)心必須要小，不然打不動，數(shu)控機床加工(gong)(gong)(gong)中(zhong)(zhong)心，在(zai)(zai)用鈷鉆(zhan)打眼(yan)時不磨槽以(yi)(yi)免在(zai)(zai)打眼(yan)過(guo)程(cheng)(cheng)中(zhong)(zhong)鉆(zhan)頭退火。根據工(gong)(gong)(gong)藝下(xia)料一(yi)(yi)(yi)般分三種：一(yi)(yi)(yi)個(ge)料一(yi)(yi)(yi)下(xia)，兩(liang)個(ge)貨一(yi)(yi)(yi)下(xia)，整個(ge)棒料一(yi)(yi)(yi)下(xia)。在(zai)(zai)車螺紋時出現橢(tuo)圓時可(ke)能是料出現松動，用牙(ya)刀(dao)多理幾刀(dao)就行了。在(zai)(zai)一(yi)(yi)(yi)些可(ke)以(yi)(yi)輸入宏程(cheng)(cheng)序的(de)系(xi)統中(zhong)(zhong)可(ke)以(yi)(yi)用宏程(cheng)(cheng)充代(dai)替子(zi)程(cheng)(cheng)序循環，這樣可(ke)以(yi)(yi)省下(xia)程(cheng)(cheng)序號(hao)，也可(ke)以(yi)(yi)避免很多麻煩。

數控加(jia)工(gong)(gong)工(gong)(gong)藝路線設計中應注(zhu)意的問題：數控加(jia)工(gong)(gong)工(gong)(gong)藝與(yu)普通工(gong)(gong)序(xu)的銜接(jie)：數控加(jia)工(gong)(gong)工(gong)(gong)序(xu)前后一般都(dou)穿插有其(qi)它普通加(jia)工(gong)(gong)工(gong)(gong)序(xu)，如(ru)銜接(jie)得不好就容易產生矛(mao)盾。因此在熟悉(xi)整個加(jia)工(gong)(gong)工(gong)(gong)藝內容的同時，要(yao)(yao)清楚(chu)數控加(jia)工(gong)(gong)工(gong)(gong)序(xu)與(yu)普通加(jia)工(gong)(gong)工(gong)(gong)序(xu)各自(zi)的技術要(yao)(yao)求、加(jia)工(gong)(gong)目的、加(jia)工(gong)(gong)特點(dian)，如(ru)要(yao)(yao)不要(yao)(yao)留加(jia)工(gong)(gong)余量(liang)，留多少(shao)；定位面與(yu)孔的精度要(yao)(yao)求及形位公(gong)差(cha)；對(dui)校形工(gong)(gong)序(xu)的技術要(yao)(yao)求；對(dui)毛坯的熱處理狀態等，這樣(yang)才能使(shi)各工(gong)(gong)序(xu)達到相互(hu)滿足加(jia)工(gong)(gong)需要(yao)(yao)，且(qie)質量(liang)目標及技術要(yao)(yao)求明(ming)確(que)，交接(jie)驗收有依(yi)據(ju)。

刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)選(xuan)(xuan)擇(ze)總的(de)(de)(de)(de)(de)原則是(shi)(shi)：安(an)裝(zhuang)調整(zheng)方便(bian)，剛性(xing)好(hao)，耐用(yong)度(du)(du)和精度(du)(du)高(gao)。在(zai)滿足加(jia)工(gong)(gong)要求的(de)(de)(de)(de)(de)前提(ti)下，盡量選(xuan)(xuan)擇(ze)較短(duan)的(de)(de)(de)(de)(de)刀(dao)(dao)(dao)(dao)(dao)柄，精密數(shu)控(kong)車(che)床加(jia)工(gong)(gong)，以提(ti)高(gao)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)加(jia)工(gong)(gong)的(de)(de)(de)(de)(de)剛性(xing)。選(xuan)(xuan)取(qu)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)時，合肥數(shu)控(kong)加(jia)工(gong)(gong)，要使刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)的(de)(de)(de)(de)(de)尺寸與被加(jia)工(gong)(gong)工(gong)(gong)件的(de)(de)(de)(de)(de)表面(mian)(mian)尺寸相適應(ying)。數(shu)控(kong)加(jia)工(gong)(gong)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)的(de)(de)(de)(de)(de)選(xuan)(xuan)擇(ze)：在(zai)進行曲(qu)(qu)面(mian)(mian)加(jia)工(gong)(gong)時，應(ying)選(xuan)(xuan)用(yong)球頭(tou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)，并且球頭(tou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)半徑應(ying)小于曲(qu)(qu)面(mian)(mian)的(de)(de)(de)(de)(de)1小曲(qu)(qu)率(lv)半徑。由于球頭(tou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)的(de)(de)(de)(de)(de)端部切(qie)削(xue)速度(du)(du)為零，因此(ci)，數(shu)控(kong)沖床加(jia)工(gong)(gong)廠，為保證加(jia)工(gong)(gong)精度(du)(du)，切(qie)削(xue)行距一般(ban)取(qu)得很密，而平1頭(tou)刀(dao)(dao)(dao)(dao)(dao)具(ju)(ju)在(zai)表面(mian)(mian)加(jia)工(gong)(gong)質量和切(qie)削(xue)效率(lv)方面(mian)(mian)都優于球頭(tou)刀(dao)(dao)(dao)(dao)(dao)，因此(ci)，只要在(zai)保證精度(du)(du)的(de)(de)(de)(de)(de)前提(ti)下，無論是(shi)(shi)曲(qu)(qu)面(mian)(mian)的(de)(de)(de)(de)(de)粗加(jia)工(gong)(gong)還是(shi)(shi)精加(jia)工(gong)(gong)，都應(ying)優先選(xuan)(xuan)擇(ze)平1頭(tou)刀(dao)(dao)(dao)(dao)(dao)。
