摘要采用一种通过改变刀具位置来调整刀具前角和后角的新方法，利用MD模拟来探索磨损行为。在本文中，一种新的改进的工具，并发现有较低的磨损相比，传统的工具。在相同的切削条件下进行模拟，使用一个工具摆动到六个不同的前角的六个不同的调整角度。通过切削力、摩擦系数、温度、径向分布函数和磨损率等分析了不同调整角度对刀具磨损行为的影响。当工具摆动到−15°时观察到最大法向力，切向力没有产生任何显著变化。也没有观察到摩擦系数随着调节角度的增加而线性变化。同时，通过最直观的刀具后刀面磨损图像，说明了-15 °时的特殊性和差异。最后，从温度和径向分布函数两个方面进一步解释了这一现象产生的原因，证明了这一现象的正确性，这与以往的研究不同。
ABSTRACT A new method for adjusting the tool rake and flank angles by changing the position of the tools was used to explore the behaviour of wear using MD simulation. In this paper, a new improved tool was used and found to have lower wear compared to conventional tools. Simulations under the same cutting conditions were carried out using a tool swinging to six different rake angles of six different adjustment angles. Further analysis of the influence of different adjustment angles on the wear behaviour of the tool by cutting force, friction coefficient, temperature, radial distribution function and wear rate was conducted. The highest normal force was observed with the tool swung to −15°, and the tangential force did not produce any significant changes. The friction coefficients were also not observed as a linear change with the increasing angle of adjustment. At the same time, the particularities and differences at −15° were illustrated, from the most intuitive tool flank wear images. Finally, the causes of this phenomenon were further explained in terms of temperature and radial distribution function and the correctness of this phenomenon was proved, which is different from previous researches.
