Provides a theoretical framework for understanding and optimizing cryogenic air MQL in grinding processes. The book explores the physical characteristics of lubricants under cryogenic conditions, the influence of low temperatures on atomization effects, droplet formation dynamics, and heat transfer mechanisms within the grinding zone.
