纳米改性金属陶瓷刀具切削塑性金属的影响规律

纳米改性金属陶瓷刀具是一种新型的刀具材料，本文通过对其力学性能的分析确定其应用的范围，并通过具体的切削实验，验证了其在加工塑性材料时具有优越的切削性能，并分别研究了进给量、切削速度及切削速度对刀具寿命的影响，推导出了切削用量三要素与刀具使用寿命之间关系的广义Taylor公式，从该公式的指数可以看出，进给量对刀具使用寿命的影响也很大，几乎和切削速度对刀具使用寿命的影响相当，实验所得出的结论将有助于合理正确地使用这种新型刀具。

Research on Cutting Properties of Nano-modified Cermet Cutter

Nano-modified cermet cutter is a new kind of tooling material. The applications of this cutter are stated by analyzing its mechanical properties, and cutting tests show that the cutter is of good cutting properties in machining plastic materials. The pattern is studied between tool life and feed, cutting speed or cutting depth. Generalized Taylor's equation is also deduced from them. The index numbers in this formula present that feed affects the tool life a lot and this is the same as the cutting speed. The conclusions will be helpful to implement the new cermet cutter reasonably and correctly.
