Surface texture is employed for drag reduction in the aviation and aerospace, since it has a positive effect on boundary layers of flow. In this paper, the triangular surface texture was formed via the rolling process. The effects of the roll gap, sheet thickness, the space and size of the triangular shape on the forming quality of the surface texture were studied. The simulation indicates that a small roll gap is benefit for forming full profile. With the decrease of sheet thickness, the forming height is greater, but the sheet flatness is poorer. The size and space of riblet have significant effects on the stress and strain distribution and forming height. When the electric current is introduced into the rolling process, the formed surface texture shows greater forming profile and better flatness. It is concluded that the electrically-assisted rolling process is a promising way of forming surface texture on metal sheets.
