Abstract

Deep cold rolling (DCR) process is a cold working process, which easily produces a smooth and work hardened surface by plastic deformation of surface irregularities. The present work focuses on the surface hardness and microstructure aspects of AISI 4140 work material, using fractional factorial design of experiments. In the present work, the influence of process parameters on the surface hardness of AISI 4140 steel were investigated for DCR process and the experimental results are compared with the empirical values. The results show that DCR process improves the surface hardness by 442%. It is also observed that the empirical results were quite close to the experimental results.
