The paper dwells upon the process of drawing cylindrical parts from sheet blanks, the thickness of which decreases in the direction from the central region to the edge according to the linear law, that studied by the finite element method in the Deform software complex. The author obtained the graphic dependences of the drawing force on the displacement of the work material flange and the thickness of its edge. In his paper the author showed the characteristics of the distribution of the thickness of the elongated part in the cylindrical part of the part, its flat bottom, as well as in the transition of the cylindrical part to the bottom. The author showed the characteristics of the change in the height of the part depending on the initial thickness of the edge of the disk work material.
