FIELD: plastic metal working, namely, system for investigating process of drawing from sheet material articles having surface portions with minimally admissible rounding radius. SUBSTANCE: master die set for investigating values of parameters characterizing sheet metal drawing process includes coaxially mounted punch and die with working surfaces reciprocal to surfaces of drawn part. Die set includes pickups for measuring at least one typical parameter of drawing process. Pickups are arranged on slide and(or) on die, they are connected with recording device and designed for measuring pressure, temperature, linear motion, vibration and so on. Readings of pickups are processed and used for correcting mathematical model of drawing process. EFFECT: enhanced accuracy of drawing process investigation. 2 cl, 1 dwg
