In this paper the author tried to highlight the friction mechanisms of plastic deformation by rolling. After rolling the steel and aluminum strips, under friction conditions, without lubricant and with mineral oil, we calculated the coefficient of friction using a calculation relation. When analyzing the rolling process of cold steel strips without lubrication, the size of the coefficient of friction was 44% higher than if we used lubricants. When rolling aluminum strips, the coefficient is about 20% higher than for steel strips. Thus, the increase in viscosity and reduction causes a decrease in the coefficient of friction.
