FIELD: mechanical engineering. SUBSTANCE: screw tap has biting and calibrating areas with deforming edges, peaks of which are made on radius ρ . Value of radius r at the peaks of deforming edges of the biting area of the screw tap increases in direction to calibrating area of the screw tap and is determined by formula, given in description. EFFECT: chipfree tap provides for metal and money saving production. 3 dwg
