N2 - Previous research has shown that hard machining can be a viable alternative to grinding of hardened materials. However, the surface integrity effects of hard machining need to be better understood due to their influence on the life of machined components. In particular, the formation of a usually undesirable white layer at the surface, and dark layer below it, needs further investigation. This paper presents the results of an experimental study showing the effects of cutting speed, feed, workpiece hardness and tool edge geometry on formation of white and dark layers in AISI 52100 steel in orthogonal machining. All of the investigated variables were found to have significant effects on the measured cutting and thrust forces, surface and sub-surface hardness variation, as well as on the white and dark layer thicknesses.
