机械制造中经常碰到球面孔的加工问题,一般情况下是在麻花钻头上磨出圆弧刃来加工。钻头刃磨圆弧刃以后,圆弧切削刃上的前角值是怎样分析的呢?钻头的结构参数又对前角值产生怎样的影响呢?只有掌握了这些规律,才能根据加工条件(工件材料、刀具 Machine manufacturing often encountered ball hole processing problems, under normal circumstances is to twist the twist drill bit to the processing. How to analyze the rake angle on the circular cutting edge after the bit sharpening the circular arc edge? How do the structural parameters of the bit have influence on the rake angle? Only by mastering these rules can the angle be machined according to the machining conditions Materials, knives
