集中论述了在实际微孔钻削加工过程中主切削刃对微钻头折断和微孔加工精度的影响。
This article focused on drilling in the actual processing of microporous main cutting edge of micro-drill breaks and microporous processing accuracy.
硬质合金刀具在不锈钢加工中，其刀具耐用度主要是取决于后刀面边界磨损而不是主切削刃后刀面的平均磨损量。
In many cases of stainless steel cutting operations with carbide tools, a tool life strongly depends on flank notch wear of depth of cut rather than average flank wear of main cutting edge.
以此为基础，提出一种通过测量主刃投影曲线间接测量主刃各点切削角度的新方法，较好地解决了任意刃形钻头切削角度的测量问题。
Then a new method is proposed to measure indirectly cutting angles of drills with arbitrary point geometry by measuring the curve of the main edge projected.
