Investigation of Tribological Mechanism of Near Dry Machining (NDM)

This paper describes tribological mechanism of Near Dry Machining (NDM). Two special setups to understand Tribological mechanism of near dry machining are designed. One is mainly to measure the behavior of some fed gases in controlled atmosphere. The other is to make sure the effectiveness of gasses like oxygen or nitrogen, and that of lubricants. As a result, oxygen has a very important roll in lubrication when steel is cut.
