This paper is devoted to experimental and numerical studies of the change in the thickness of a thin-walled meniscus-shaped part along the meridian during stamping with lead. Rational values are proposed for the conditions of contact interaction in the matrix — workpiece — ductile metal system, which ensure the best coincidence of the numerical calculations results with experiments. The results obtained are applied to numerically analyze the influence of the radius of the lead-in part of the matrix on the thickness of the meniscus part in the dome part. The presence of a rational value of the radius of the lead-in part is established, which provides the smallest decrease in the thickness of the part in the dome when stamping with lead.
