Abstract

Surface friction plays a significant role in the machining performance and life of cutting tools. This investigation examines the influences of laser produced periodic textures on lubrication across the tool's rake face and the influence on cutting forces when orthogonal turning steels exhibiting ductile chip behaviour. Laboratory tribology and orthogonal turning experiments on TiCN/Al2O3/TiN CVD coated tool inserts enhance understanding of the role of textures in the reduction of cutting forces and coolant film behavior in the sliding pairs by showing shifts in lubrication regimes from boundary to mixed and hydrodynamic, depending on operating parameters, texture design and coverage.
