Abstract
In designing the regular polygonal section shape drawing process, it is convenient to use analytical expressions allowing us to estimate effectively the effect of different process factors. A design procedure of stress calculation for this process is proposed. The ratios for calculation of drawing stress, optimum angle of the drawing tool hole, limit value of deformation degree in using the standard tool and index of stress state in the axial part of the deformation zone are obtained. The use of drawing tools with optimum angles reduces the accumulation rate in the metal structure and in case of repeated drawing allows us to cut down the number of intermediate heat treatments.
