The article investigates the influence of the relation between the drawing and flanging coefficients on the stability of the combined process when obtaining double walled profile rings. The finite element method has been used. In order to assess the stability the walls height is fixed. The relative thickness and coefficients values pairs ratio diagram for the process stability has been built.
