The concept of cutting tool life-cycle management was put forward, and divided it into four phases: planning period, input time, serviceable life and discarding period.
提出了刀具全生命周期管理的概念，将刀具全寿命周期管理划分为计划期、投入期、使用期、报废期四个阶段。
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。
Since only a few of the cutting edges are engaged with the workpiece at a time, heavy cuts can be taken without adversely affecting the tool life.
由于同一时间只有部分切削刃切削工件，因此可以在对刀具寿命没有不利影响的情况下承担重型切削。
