The burnishing process was developed and designed for the finishing of the workpiece to reduce the production time. This research was to study the burnishing on AA5052 aluminum alloy which affects the surface roughness. The Taguchi method was used to determine the appropriate factors (speed, feed and burnishing Force) for optimization of production processes. From the experiment, the results showed that the condition of the burnishing process was the speeds 200 rev/min, the feeds 0.5 mm/rev and burnishing force 200 N, which had the average surface roughness as low as 0.47 µm and the S/N ratio was found to be 6.53. In the repeated trials, it was found that the values were closed to the first experiment by calculating via the Taguchi method, which was considered acceptable by estimated model coefficients of 98.14%. Therefore, the Taguchi method could be used to design an efficient burnishing process for AA5052 aluminum alloy.
