FIELD: mechanical engineering. SUBSTANCE: method involves providing multiple percussion actions of equal force and penetration extent by punch onto part placed on rigid continuous base; separating by shear at first cycle, with separating shear effect being further enhanced by the action of part positioned below punch; completely dividing part into portions. EFFECT: increased efficiency in obtaining smooth division surface by providing cooperative motion of division surface and punch percussion actions and reduced material consumption for manufacture of working tool. 3 dwg
