A brief review on cryogenics in machining process

Abstract

Machining processes aided by cryogenics, and therefore known as cryogenic-assisted machining, are one of the emerging sustainable means of machining superior quality products. The major objective of this work is to brief the readers with the advancements and developments taking place during last few decades in this emerging area of machining technology. The work incepts with an introduction section encompassing delineation of the conceptual framework of cryogenic-assisted machining processes, i.e., the definition and scope of the processes. Subsequently, the readers are illuminated with the thermal aspects of the cryogenic-assisted machining processes. Main applications of the cryogenic-assisted machining processes are discussed next. Consequently, economic aspects have been delineated in the penultimate section of the present work. The sustainability issues associated with the cryogenic-assisted machining have also been discussed in the present work. The work finally terminates with brief concluding remarks encompassing future perspectives.
