In this paper, we develop a methodology to determine flow stress at the machining regimes and friction characteristics at the tool-chip interface from the results of orthogonal cutting tests. We utilize metal cutting analysis originally developed by late Oxley and present some improvements. We also evaluate several temperature models in calculating the average temperatures at primary and second...

Abstract Graphene has been shown to be a promising solid lubricant reduce friction and wear of the sliding counterparts, currently is reported only function below 600 °C. In this study, its potential as above °C was studied using ball-on-disc tribo-meter rolling mill. Friction results suggest that reduction up 50% can obtained with graphene nanoplatelets (GnP) under lubricated conditions betwee...
