Investigation of a manufacturing process with several eccentric and non-circular cross sections trough a non-circular rolling operation

The non-circular rolling is a pressure forming method with material displacement normal to the rotational axis of the billet. It consists in workpiece forming by means of a wavy wedge tool segments fixed on a flat or concave plates of rolling mills. Here for the billet is positioned between two in the oppositely moving, wavy profiled plates and the cross section stays constant. The goal of this project is to roll a part with several out of round, eccentric and a combination of both forms in one forming operation. The out of round wedge rolling is a forming operation to optimize the mass distribution of a preform.
