Abstract: The severe urge for need of cleaner machining techniques has led to continuous exploration of various alternative cooling and lubrication methods. Surface integrity of machined components play a crucial role, but the same cannot be the only criteria for deciding on the machinability aspects as well as eco-friendliness of specific machining approach. This paper proposes a model for sustainability assessment of machining considering surface integrity aspects along with machining environment aspects for better understanding of sustainability in machining. High-speed turning of Inconel 718 at varying MRR levels depicting productivity rates has been carried out under dry, flood coolant and water vapour machining environments, and then sustainability assessment has been carried out using the developed model. Within the investigated experimental regime, the results show that the use of water vapour as coolant and lubricant in machining gives highest product sustainability index (PSI) of 82.92% thus suggesting it to be a promising eco-friendly machining technique.
