Multiresponse optimization of process parameters in drilling is focused in this article using the TOPSIS technique to obtain minimum cutting temperature (T), thrust force (F-t), torque (M-t) and surface roughness (R-a), Circularity (Cir), Cylindricity (Cyl). The experiments were performed on Titanium alloy Ti-6Al-4V in different cooling environments: Wet cooling and cryogenic cooling conditions. Liquid nitrogen (LN2) as a coolant is used in cryogenic machining. The control factors selected were machining environments, cutting speed (V-c) and feed rate (f). Eighteen experiments were conducted in wet and cryogenic LN2 conditions based on L-18 orthogonal array, respectively. The optimization results indicate drilling at V-c = 40 m/min and f = 0.02 mm/rev which is of the lowest value in cryogenic LN2 condition. A better performance is achieved too. The optimum multiresponses show that TOPSIS method is the most effective performance in the drilling process.
