This article describes a method flanging round holes in sheet blanks and profiles which consists of the steps of forming holes cold extrusion to produce a profiled workpiece, punching coffers and flanging.The product after the flanging has a constant wall thickness and a smooth cylindrical surface.The article contains an engineering method to determine the dependence for determining forces of flanging profiled billet spherical punch and the size of the source profile. It shows flanging holes processing profiled billet and flanging with thinning which was carried out by finite element method and it also shows the comparison of results of two methods.
