Abstract : One of the major issues faced while machining Aluminium and its alloys is built up edge and hence reduced tool life and surface finish. Turning temperature and friction have to be reduced to avoid sticking and built up edges. This work deals turning of AL 6063 rod at two environments a) Pre cooling to sub zero temperature using dry ice and b) Dry turning at room temperature. Depth of cut is kept constant at 2.5 mm. Turning inserts CNMG 120408 MP TT 5100 and CCGT 120408 FC K10 - 1 were used. Cutting speeds of 70, 110, 175 m/minand feed rates of0.2, 0.315 and 0.4 mm/rev were used. The surface roughness, Ra, Rz, material ratio Mr1 Mr2, tool wear are measured. Increase in productivity and cost saving were evident while using CNMG 120408 MP TT 5100 under pre cooled turning environment. © 2015 The Authors. Published by Elsevier B.V.
