Abstract: Cryogenic processing methods are environmentally-clean, toxic-free, and safe sustainable manufacturing processes, which also provide improved surface integrity, superior functional performance and greater product life in manufacturing processes. This paper presents a summary of findings from a preliminary study of the cryogenic cooling effects in a machining process. Various heat transfer scenarios need to be built into the model to consider the boiling phenomena. Cryogenic turning process includes a large radial thermal gradient in a thin layer of machined surface and changes the dynamic recrystallization process. A high speed, wide range temperature measurement system was developed, and preliminary experiments are carried out, investigating the contributing factors and the proper boundary conditions for modeling of cryogenic machining processes. The transition from slow cooling to a rapid cooling is observed.
