On the kinetics of forming an oxide film for lubrication when cutting steel in a controlled atmosphere

An experimental study of the steel-cutting process in a controlled atmosphere is performed. Based on the results, a theoretical model is developed to evaluate the kinetics of the formation of an oxide lubricating film under steel cutting and to optimize the cutting process by decreasing the cutting...

Description
Summary:An experimental study of the steel-cutting process in a controlled atmosphere is performed. Based on the results, a theoretical model is developed to evaluate the kinetics of the formation of an oxide lubricating film under steel cutting and to optimize the cutting process by decreasing the cutting forces and the wear and tear of the tool. The performed studies showed that, for the manifestation of an effective lubricating effect of pure oxygen due to the formation of a separating protective film of adsorbed oxygen, it is necessary to maintain a pressure of more than 1.32 Pa.
