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.
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。
To improve a tool life in this case, therefore, the flank notch wear must be depressed to generate.
为了提高刀具耐用度，就必须减小后刀面边界磨损。
This was due to the increase in the contact area at the tool-chip and tool-work interface due to the presence of flank and crater wear.
这是由于增加了接触面的工具，芯片和工具的工作界面因侧翼和火山口的磨损。
