The paper presents experimental results of investigations on deep drawing process of cylindrical drawpieces without collar in four drawing steps (single draw and three redraws). The research involved the use of EN AW-1050A aluminium blanks with diameter D = 66 mm. The material was prepared by rolling with different relative rolling reductions (z = 5%; 10%; 15% and 20%, respectively) at rolling mill DUO-100 and blanking process. In investigations of deep drawing, experimental force waveforms as the function of displacement for different relative rolling reductions of sheet metal made from aluminium were obtained.
