Under high temperatures (such as in HSM), tribo-films can be generated at the frictional surfacesduring cutting [20]. They are formed due to interactions between the workpiece, the tool material,and the environment. Oxygen from the environment can penetrate along the tool-chip interfaceand react with active elements near the surface to form different tribo-films [11]. Different typesof tribo-films can be generated in this way [21]; protective and thermal barrier tribo-films reducechemical tool wear and help to decrease the thermal effects on the cutting tool. They can also act ashigh-temperature lubricants, lowering the adhesion effect of the chip on the tool face [22].
