的(de)辦法是向斜下方進刀，馬鞍山數控加(jia)工(gong)(gong)(gong)(gong)，進到一定深度后(hou)再用(yong)(yong)(yong)側刃橫向切(qie)(qie)(qie)削(xue)(xue)。在銑削(xue)(xue)凹槽面時，可以(yi)預鉆出(chu)工(gong)(gong)(gong)(gong)藝孔以(yi)便下刀。用(yong)(yong)(yong)球頭銑刀垂直進刀的(de)效(xiao)果(guo)雖然(ran)比(bi)平底的(de)端銑刀要(yao)好(hao)，數控加(jia)工(gong)(gong)(gong)(gong)報價，但(dan)也因(yin)軸向力過大、影響切(qie)(qie)(qie)削(xue)(xue)效(xiao)果(guo)的(de)緣故，不(bu)使用(yong)(yong)(yong)這種下刀方式。數控加(jia)工(gong)(gong)(gong)(gong)。數控加(jia)工(gong)(gong)(gong)(gong)模具應(ying)(ying)該注意什么球頭銑刀在銑削(xue)(xue)曲面時，其(qi)刀尖處(chu)的(de)切(qie)(qie)(qie)削(xue)(xue)速度很低，如果(guo)用(yong)(yong)(yong)球刀垂直于被加(jia)工(gong)(gong)(gong)(gong)面銑削(xue)(xue)比(bi)較平緩的(de)曲面時，球刀刀尖切(qie)(qie)(qie)出(chu)的(de)表面質量比(bi)較差(cha)，所以(yi)應(ying)(ying)適當地提高主軸轉速，另(ling)外還應(ying)(ying)避免用(yong)(yong)(yong)刀尖切(qie)(qie)(qie)削(xue)(xue)。
