Раскатывание резьб, М ., 1974, с. 17, рис. 14 д.The cross section lies in the longitudinal plane of the HG, squeezing about the tool axis by an amount K, on which the axes of the radii are thus mixed. Deforming protrusions 1. When machining the thread, the deforming torture enters into operation sequentially from the top to the bottom, forming LIJII contact with the thread profile parts located at an angle to the velocity vector, which allows the metal to move, to sweep the free zone in the direction of the profile of b6. and by that1: .1M eat; zhpet efforts needed to form a thread. 854 Claims for plastic threading, containing helical lines arranged along a helical line, deforming protrusions made along a radius, ground out in outer and middle diameters, characterized in that, in order to improve the conditions of deformation, the axes of deforming protrusions are offset relative to the axes of symmetry of the tap .
