In this paper the basic cutting characteristics such as cutting forces, cutting power and its distribution, specific cutting energies and friction were determined as functions of variable tool corner radius ranging from 400 to 1200 µm and the cutting speed ranging from 150 m/min to 270 m/min for a hardened 41Cr4 alloy steel of 55±1 HRC hardness in finish turning steel using chamfered CBN tools. Moreover, selected roughness profiles produced for different tool corner radius were compared and appropriate surface roughness parameters were determined. The measured values of Ra and Rz roughness parameters were compared with theoretical values and springback effect was taken into account.
