Abstract: During cold forming process, the use of an oscillatory motion die brings economic advantages because ensures higher worked piece deformation degrees, even when equipment installed power is smaller than in the conventional one case. The frontal contact surface between tool and worked piece is floating and represents only a part from the whole one. The paper studies material flowing mechanism in cases of pieces having different shapes and these processes dynamics.
