Optimization of Cutting Parameters in Hole Machining Process by Using Multi-objective Taguchi Approach

29427

In this study, effects of drilling parameters on the various surface roughness characteristics; arithmetic average roughness (Ra), geometric average roughness (Rq) and average maximum height of the profile (Rz) in the wet drilling of AA 5754 Aluminium alloy were experimentally investigated. Cutting speed, feed and depth of cut were considered as control factors; Ra, Rz and Rq were considered as response factors. Experiments were designed according to Taguchi L9 orthogonal array. Varience analysis was performed to determine the importance of control factors on the surface roughness. The percent contributions of the control factors on the surface roughness were obtained to be feed (71.32%) and cutting speed (22.20%). Minimum surface roughness values Ra, Rz and Rq were obtained 120 m/min cutting speed, 0.10 mm/dev feed rate and 0.75 mm depth of cut by using multi-objective Taguchi approach.
