Industry is under increasing pressure of global competition, stricter environmental legislation and supply-chain demand for improved sustainability performance. The latter can be achieved through changes in products, processes. This research disseminates work related to sustainable cryogenic machining that has a high potential to cut production costs, raise the performances, and improve competitiveness by reducing resource consumption and creating less waste. The details about cryogenic fluids and their use in machining processes as an alternative to oil-based emulsions are presented.

An experimental study has been performed to investigate the capabilities of dry, conventional and high pressure jet assisted turning of two different hard-to-machine materials, namely hard-chromed and surface hardened Ck45 and Inconel 718. The capabilities of different hard turning procedures are compared by means of chip breakability, technological windows, cooling lubrication efficiency, and cutting forces. All machining experiments are performed under conventional cutting speeds using coated carbide tools.
