Milling is a common machining technology in the hardware industry,where the rational selection of cutting parameters not only improves the efficiency of the tool but also significantly affects production costs and product quality[1].Based on this,the present study explores the effects of different parameters on the cutting performance during the milling process of 6061-T6 aluminum alloy through finite element simulation and experimental methods.By establishing a finite element model of 6061-T6 aluminum alloy,the study analyzes the impact of milling depth,milling width,and spindle speed on cutting force and temperature.The research indicates that milling depth has the most significant influence on cutting force,while milling width most notably affects temperature.The deviation between simulation results and experimental data remains within 30%,demonstrating that the simulation data are highly reliable.This proves that the simulation model can effectively reflect the actual milling process,providing a theoretical basis and practical guidance for the milling machining of 6061-T6 aluminum alloy,and aiding in the optimization and control of milling parameters in industrial applications.
