An investigation was carried out about the possibility of increasing the material utilization coefficient by excluding the flange rimming operation after the first drawing process. The dependency of the earing height on the drawing ratio and anisotropy was determined by means of the «AutoForm» simulation tool. The simulation results allow one to determine the necessity of cutting the flange depending on the required tolerance for the drawn part. Sensible anisotropic parameters, which take essential influence on the materials earing behavior, are determined. Furthermore, connections between the earing height and anisotropic parameters are built.
