摘要

The current research focuses mainly on the manufacturing industries in terms of energy savings and cleaner production in order to impart sustainability. The use of conventional cutting fluid is not beneficial for high cutting speeds and feeds, as it can lead to increased tool wear and reduced machining efficiency. In addition, such cutting fluid contaminates the atmosphere in high-production machining, leading to environmental concerns and potential health risks for workers exposed to these harmful substances, such as respiratory issues and skin irritations from prolonged exposure to the chemicals present in the fluid. Cryogenic cooling is useful in lowering the high-flow cutting temperatures, which increases the quality of the workpiece and tool life. This review comprehensively analyses the relevant literature on cryogenic cooling in various machining processes. It provides a review and summary of cryogenic cooling, analyzes and evaluates benefits and developmental challenges in each area, and outlines the future developmental directions of cryogenic cooling. These cooling techniques are found to enhance the sustainability of machining processes and production as a whole, particularly by reducing energy consumption and minimizing waste generated during manufacturing. This study aims to develop new strategies for the research and development of cryogenic cooling technology in machining industries.
