In order to investigate the impact of various milling parameters on the milling force during the ultrasonic vibration-assisted milling process of 7075 aluminum alloy, orthogonal experiments were designed. The experimental data indicated that selecting a higher spindle speed, a lower feed rate, and a smaller milling depth could effectively reduce the milling force. Through analysis, the optimal milling parameter combination was determined to be: n=5500 r·min-1, vf=600 mm/min, and ap=0.2 mm. Furthermore, by measuring the surface roughness of the machined workpieces, it was found that the milling depth, spindle speed, and feed rate affect the surface roughness in descending order, further validating the effectiveness of the obtained optimal milling parameters.
