FIELD: plastic metal working.
SUBSTANCE: invention can be used at plastic shaping of parts by orbital deformation method. Blank is made previously profiled in form of cylinder with ring flange. Dimensions of blank are defined by mathematical expression given in invention. Blank is placed between die and spherodynamic fluctuating deforming module and then is spinned. Ring flange of blank is made for providing its arrangement between die and said deforming module with clearance. Size of clearance between ring flange and die exceeds clearance between ring flange and deforming module by a factor of 10.
EFFECT: provision of deformation resonance in material in process of machining for realizing wave plasticity character in form of rotary modes of plasticity.
