The research presents a multi-objective optimization of the slide burnishing process applied to 36CrNiMo4 steel, aiming to enhance surface quality and mechanical properties. The study focuses on key process parameters, including burnishing force, feed rate, and burnishing speed, and their effects on surface roughness, microhardness, and residual stress. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach is employed to identify optimal parameter settings that balance multiple objectives simultaneously. The conducted research demonstrates significant improvements in the treated steel components and the process parameters: P = 120 N, f = 0.04 mm/rev, n = 900 rev/min were found to be the most advantageous. The proposed optimization framework provides an effective decision-making tool for process engineers to achieve superior surface integrity in slide burnishing applications.
