Abstract : pChip plays a key role in turning. One of the parameter for characterization of chip is chip reduction co-efficient which determines forces involved and in turn Energy consumption. Energy consumption during turning and chip reduction co-efficient are directly proportional. 95% of energy while turning is spent on Heat loss. Due to higher speed, Feed and depth of cut along with material removal rate, the heat produced during turning is also increased. Hence efforts are made to reduce chip reduction co-efficient to reduce heat produced and Energy consumption. An experiment was conducted on turning of EN8 (AISI 1040) steel rod at different speeds and feeds with constant depth of cut of 1.5mm under two different environments namely cryogenic cooling environment using dry ice and dry turning environment. Chip reduction co-efficient found to be significantly lesser in dry ice cooled turning environment than room temperature turning environment at higher cutting speeds and feed rates which reduces the main cutting force. The dry ice pre cooling also helps in achieving sustainable manufacturing. © 2017 Elsevier Ltd./p
