Tribological Effects in and by Metal Cutting

Abstract

In metal cutting, a severe thermo-mechanical load collective determines the friction and wear behavior at the tool-chip interface. The inaccessibility of this interface complicates studies and thus the understanding of tribological effects in metal cutting. During a tool’s lifetime, local friction conditions change drastically as coatings and tool geometry wear down. This paper shall provide a comprehensive overview of current methods to understand and describe friction conditions in metal cutting and how cutting induced surface layer states may influence the friction and wear behavior of the finished workpiece.

Friction behaviors in the metal cutting process: state of the art and future perspectives

“…Because plastic volumetric deformation altered the development of the contact condition, the cutting friction could not be regarded as a pure surface effect [46]. Moreover, the interface friction in the cutting process was not a simple sliding friction process but involved the complex sticking contact state [47]. The balance between sticking and sliding forms could change with the dynamic cutting friction conditions.…”
