本文研究了聚晶金刚石(PCD)刀具和硬质合金刀具K10(硬质合金)在加工铝合金(Al 7075-0)时的热性能和力学行为，并对两种刀具的性能进行了比较。这项研究是使用商业有限元软件进行的。该软件界面友好，可输出切削力、温度、压力、等效应力、最大剪应力、塑性应变和塑性应变率等结果。通过对模拟结果的分析，得出结论：与硬质合金刀具相比，多晶刀具在切削力、进给力和温度方面都具有更好的性能。
The purpose of this paper is to study the thermal and mechanical behaviour in machining of aluminium alloys (Al 7075-0) using PCD (polycrystalline diamond) and K10 (cemented carbide) tools and to make a comparison between the performances of both tools. The study was made using a commercial finite element software. This software has a user friendly interface and can output several results including cutting forces, temperature, pressure, von Mises stress, maximum shear stress, plastic strain, and plastic strain rate which were the objectives of this study. By analysing the simulations, it was concluded that the polycrystalline tool has a superior performance in terms of cutting and feed forces and temperature when compared to the cemented carbide tool.
