Cryogenic cooling-based sustainable machining

Abstract

Machinability is the most important indicator to measure the performance of any machining operation. Cutting force, surface roughness, tool wear, dimensional accuracy, and cutting temperature, etc. are the most important machinability indicators. Various materials such as inconel, titanium, haynes, and waspalloy, etc. are difficult-to-machine (DTM) materials. Cryogenic cooling is one of the techniques to improve the machinability of these materials, and found effective specially when machining at high speed. This chapter sheds light on cryogenic cooling-based machining, its working principle and mechanism, and case studies on cryogenic cooling-based machining of various DTM materials. © 2020 Elsevier Inc.
