In the present work, the drilling experiments are performed on Aluminum 6061-T6 and Brass C360 alloy block of 8mm thickness using HSS Twist drills by means of universal drilling machine. Cutting parameters drill diameter, speed and feed rate are varied at 3 different levels. A number of drilling experiments are conducted using the L9 orthogonal array according to Taguchi design of experiment (DOE) on both materials separately. The output performances viz. MRR, surface roughness, torque and cutting forces are recorded for each run. Multi objective optimization technique WASPAS (weighted aggregated sum product assessment) method is used for determining the optimal drilling parameters resulting in minimum Surface roughness, Torque, cutting force and Maximum MRR. The measured responses were analyzed and the Influence of drill parameters on output responses such as metal removal rate and surface roughness, cutting force, torque is studied. After nine experimental trials, responses are compared for Al 6061-T6 and Brass C360 alloys.

Multi objective optimization technique WASPAS (weighted aggregated sum product assessment) method is used for determining the optimal drilling parameters resulting in minimum Surface roughness, Torque, cutting force and Maximum MRR.
