Using Metrics to Assess the Sustainability of Cryogenic Machining

Abstract

Cryogenic machining is considered the most environmentally friendly alternative to the more prevalent flood-cooled, near-dry, and dry machining technologies. This article explores the use of a sustainability evaluation method for manufacturing processes, with a focus on cryogenic machining methods. Our investigation is predicated on Process Sustainability Index (Process) metrics. To To determine the best conditions for cryogenic machining, studies are conducted using a variety of machining parameters as adjustable variables, including cutting speed and coolant flow rate. From an eco- friendly production standpoint, process analysis helps choose the best cutting settings. During the assessment phase, the process's behaviour is taken into account under different process conditions, and its controllability and mechanism are analysed to improve sustainability.
