Controlling the heat, generated during the cutting process, is an important.lactor in.improving the quality of the product and performance of the machining. A vortex tube was (liaployed to ewthiate the effects of cooling on the turning parametei-s. Various cutting parameters (100 M/min, 250 mfmin and 400 m/min) together with various cooling temperatures (-4 degrees C, 8 C and 20 degrees C) vere considered to find surface roughness, cutting force and cutting temperature. Response surface.mahodology was used to optimize the experimental paramet(TS. Till best attainable surface roughmss 1,Ine was found to be 0.77 mu M Ra, under the conditions of 0.15 mm/rev feed, 400 at/min cutting speed, -4 degrees C (with vortex tube) cutting temperature and 1.2 mm tool edge radius. Cutting forces were not affected by the temperature changes. The difference was negligible and as small as 1%. The minimum cutting temperature was 74.17 degrees C, which Avas obtained under the machining conditions of 0.25 mm feed, 250 M/min cutting speed -4 degrees C (with vortex tube) cutting temperature and 0.8 mm tool edge radius.
