FIELD: process engineering.
SUBSTANCE: invention relates to metal forming. Proposed method comprises making tubular billet, barrel forged piece radial reduction to obtain curved generating line of outer surface. Reduction at radial reducing machine is carried out with the help of master cam and servo drive with sensing roller that may roll on over said master cam. Barrel forged piece outer surface has curved generating line made up of two section. One section on muzzle section is located at internal angle while at another it is located on breech housing side. Said sections are conjugated by conjugation radius proceeding from definite relationship. Final machining includes cutting.
EFFECT: higher precision.
