The purpose of this paper was to obtain a comprehensive understanding of the relation between cutting data and surface integrity, in terms of residual stresses and surface roughness, during hard turning with PCBN inserts in 18MnCr5 case carburised steel. In the study, fractionally reduced CCF test plan was used. It was found that the effect of cutting parameters on residual stress could only be predicted at 0-50 μm below the surface. The cutting geometry and data can be changed to alter the residual stress in area referred to above. The surface roughness values were mainly influenced by the feed rate and nose radius.
