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].Due to the relatively high cutting forces produced during cutting of hardened materials [23],determination of these forces is essential for not exceeding the elastic limit of theMachine-Fixture-Tool-Workpiece (MFTW) system [24]. The increase of the cutting forces abovethis limit usually affects the dynamics of the machining process and can cause chatter. Therefore,reaching a range of cutting speeds results in decreasing the cutting forces can positively influence thestability of the machining process and the accuracy of the machined component [25]. Moreover, it candecrease the power consumed during cutting.
