Aluminium alloys have become the most common material for structural components in most engineering fields because of their unique properties. At some point during the manufacturing process, the material must be drilled to create holes for bolts or fasteners that will be used to attach or join other components. Drilling must be optimised in terms of quality and precision in order to meet the industry’s high standards, as there is a high rejection rate due to these factors. By adjusting the key drilling parameters, it would be possible to save money, time, and effort while enhancing the quality. This study dives into the impact of cutting parameters and coolant on drilling Al6082-T6 aluminium alloy. The focus rests on addressing issues related to internal surface roughness. Experiments were conducted both dry and wet using CNC machines and HSS drills with varying spindle speeds (v) and feed rates (f). ANOVA analysis was used to pinpoint the influence of factors on surface roughness. A comparison is made between drilling with and without coolant. Results reveal that feed rate affects surface roughness, while spindle speed was minimal. Optimal parameters for improved surface roughness were v = 4500 rpm and f = 150 mm/min in dry drilling. Notably, drilling conditions (dry/wet) have the greatest impact (28.8%) on surface finish, followed by spindle speed and feed rate.
