Abstract Aeronautical applications are permanently improving because of the excellent mechanical capabilities of glass-fiber-reinforced polymers (GFRP). Drilling is a vital machining task required to put the structures made of these composites together. However, these GFRP composites need more precise machining than metallic materials. This machining procedure causes delamination in the composite composition. Delamination at the exit and entry of drilled holes is a severe problem for composite materials. By maximizing the controlling variables of the drilling process, superior-drilled holes can be generated. The present study aims to optimize the drilling settings by considering various performance aspects using the entropy weight-coupled proximity indexed value method. For this study, Taguchi’s L25 5-level orthogonal array was employed. The responses are at the exit, entry delamination, and thrust force, while the control variables are feed rate and spindle speed. The findings indicate that more significant spindle speeds and smaller feed rates improve drilling success. Furthermore, current research indicates that feed rate has a more significant impact on the quality of the drilling holes.
