Cryogenic Machining Sustainability Assessment using Metrics

Abstract

When compared to the more common flood-cooled, near-dry, and dry machining methods, cryogenic machining is seen as the greenest option. Cryogenic machining techniques are the topic of this article, which discusses the implementation of a sustainability assessment approach for manufacturing processes. Metrics from the Process Sustainability Index (Process) serve as the basis for this analysis. To Different machining parameters, such as the cutting speed and the coolant flow rate, are employed as the tunable factors in the experiments to address the optimal process conditions for cryogenic machining. The Process analysis aids in selecting the optimal cutting parameters from a green manufacturing perspective. Analysis of the process's mechanism and its controllability for enhanced sustainability is conducted throughout the assessment phase, with consideration given to the process's behavior under a variety of process circumstances.
