Abstract : Achieving ideal surface roughness is always a challenge in machining industry. An experimental study was conducted on dry turning of EN8 (AISI 1040) steel rod in two different turning environments namely pre cooling to Sub Zero temperature up to-45°Cand room temperature in dry condition using four different cutting speeds 30, 49, 78, 123 metres/minute and feeds 0.18,0.315,0.4 0.5 mm/revolution respectively at 1.5mm depth of cut. Dry ice was used for pre cooling the steel rod. The various aspects of surface roughness are studied and a regression model is created for predicting the surface roughness. © Research India Publications.
