外文摘要：This paper aims to investigate the impact of various cutting parameters on the micro-cutting mechanism of high-entropy alloy FeCoCrNiAl0.6. It examines the cutting force, cutting temperature, and residual stress of FeCoCrNiAl0.6 high-entropy alloy micro-cutting using the finite element simulation method. The research findings reveal the following: as the cutting depth increases, the three-dimensional cutting force gradually rises, exhibiting a significant growth trend, and there is a positive correlation between them. Increasing the cutting speed results in small fluctuations in cutting force, which remains relatively stable. Moreover, the cutting force gradually increases with higher feed rates, demonstrating a positive correlation. The maximum temperatures of the tool surface and chip surface increase with higher cutting depth, and they are positively correlated. There is a positive correlation between cutting temperature and cutting speed. With increased cutting speed, the maximum temperature of the cutting surface steadily rises. Simultaneously, during cutting, the chip temperature increases at a faster rate compared to the tool temperature with increasing cutting speed. As the feed rate continuously increases, the maximum temperatures of the chip surface and tool surface show a steady growth trend, and there is a positive correlation between them. During the cutting process, the workpiece surface is predominantly characterized by residual compressive stress. Under different cutting depths, the absolute value of the maximum residual compressive stress on the workpiece surface decreases. Under the influence of cutting speed, when the cutting speed is below 110 mm/s, the residual compressive stress on the workpiece surface demonstrates an increasing trend. For cutting speeds between 110 and 170 mm/s, the workpiece surface initially exhibits a decreasing trend followed by an increasing trend. Increasing the feed rate leads to an increase in the absolute value of the maximum residual compressive stress on the workpiece surface.
