Improving surface hardness is a method to increase the component resistance against fatigue and fretting fatigue. Deep rolling (DR) process can be utilized as a fast, effective and economical method to improve surface hardness of industrial components. The effects of deep rolling (DR) parameters on the surface hardness of 7075-T6 aluminum alloy have been investigated in this paper. Fractional factorial design of experiment (DOE) has been used to study the effect of DR Parameters such as ball diameter, feed rate, rotational speed of specimen, penetration (rolling depth) and rolling pass number on the surface hardness. For the experimental work, an innovative, simple and inexpensive rolling-setup was designed and fabricated. The set-up is mounted on lathe machine. The results indicate that feed rate, penetration and rolling pass number are the most influential factors than ball diameter and rotational speed.
