<p>Chips are formed during turning. Chips take away most of the energy in the form of heat which is non productive. The chip handling and disposal is always a difficult process. The use of metal cutting fluids calls for better disposal management to due strict environment norms worldwide. Aluminium alloys are used extensively in aerospace and structural industries. Hence it becomes important to study about chip in terms of its shape, size and process of separation while turning. This work discusses about chip morphology of Aluminium alloy 6063, in terms of chip types and chip reduction coefficient in two different environments, namely cryogenic pre cooled environment using dry ice and dry turning environment. AA 6063 rods are pre-cooled in a closed chamber for 36 hours. Two types of inserts are used one being a high positive rake insert (CCGT 120408FC K10 -1)which is used for turning Aluminium alloy and another is a general purpose insert (CNMG120408 MP TT 5100)used very commonly in workshops. Feed rates of 0.2, 0.315, and 0.4 mm/rev and Cutting speeds of 70,110,175 m/min are chosen for experiment with a constant depth of cut of 2.5mm. © 2017 Elsevier Ltd.</p>
