Improvement of machinability of hard to machine materials by cryogenic cooling and job preheating

This paper presents the impacts of applications of cryogenic and plasma preheating used separately and in combination on chatter and machinability of stainless steel during turning. An effective cryogen delivery system was developed to supply liquid nitrogen. The low temperature of liquid nitrogen c...
