Computational aspects of tribology in metal machining

Abstract The present paper reviews tribological phenomena in metal machining from computational aspects. Emphasis is laid on the interaction between the mechanical aspects of tribology and the characteristics of the cutting process. Firstly, the fundamentals of the mechanics and physics of cutting processes are outlined. This is extended to friction and lubrication at the tool-workpiece interface and tool wear. On the basis of this quantitative knowledge, the interaction of tribology with a cutting process is demonstrated by means of computer simulation including machinability of free-cutting steels, cutting fluid action and prediction of tool wear. Finally, concluding remarks are devoted to the interaction of tribology with wider aspects of cutting towards the goal of ‘better machining‘.
