Effect of cutting parameters on the generated surface integrity of hard-turned martensitic AISI 52100 bearing steel

Hard turning offers improved manufacturing efficiency but requires great control of the cutting process to achieve required machining-induced surface integrity with respect residual stresses, topography, and near-surface microstructure. This research work is focused on studying effect speed, feed rate, depth cut, chamfer angle, coolant pressure after hard martensitic AISI 52100 steel. The results showed that rate had a significant influence stresses topography. discontinuous mechanically induced white layer was observed at high speed angle increased thickness.
