This paper investigates the influence of cutting parameters such as drilling speed and feed rate on burr size when drilling 5A02, 5A06, 6061, and 6063 aluminum alloys on a CNC machine tool. An experimental plan using the full factorial method was employed to obtain experimental data. Methods such as signal-to-noise ratio (S/N) and analysis of variance (ANOVA) were used to analyze the main factors affecting burr formation. By observing the S/N ratio and ANOVA, the optimal set of process parameters was selected, the significance of the process parameters was evaluated, and the cutting parameters were optimized to achieve the purpose of reducing and suppressing burr formation. Through verification experiments, the optimal combination of process parameters was determined. The results show that the optimal process parameter combination for 5A02 aluminum alloy is a drilling speed of 5000 r/min and a feed rate of 0.02 mm/r. The optimal process parameter combination for 5A06, 6061, and 6063 aluminum alloys is a drilling speed of 3000 r/min and a feed rate of 0.02 mm/r. Among all parameters, the feed rate has a relatively large impact on the generated burr height and thickness, and is an important drilling parameter affecting burr height and thickness, while the effects of other factors are not significant.
