The main idea of the work is to create scientifically grounded technological conditions for treatment of tab grooves in the discs from heat resisting steel, which stipulate formation of roughness of treated surfaces at the level of design requirements, useful compressive residual stresses and a defective surface layer, which increases reliability of operation of interlock in the absence of any defects on the working surfaces of tab grooves of various types, under conditions of maximizing efficiency of their treatment method. Dependences of roughness of the treated surface on the technological factors of the broaching process Ra = f (V, S, γ, HRC) have been proposed. As a result of experimental studies, the nature of distribution of residual stresses, depth and degree of strengthening of the surface layer, depending on the technological conditions of the tab grooves treatment, has been established. The article presents research of surface quality parameters; study all the selected parameters of the surface quality and surface layer and an algorithm to perform experimental work. The algorithm has been built on major principles of control and fixation methods, which stipulate use of non-destructive methods of control. Graphs of strengthening the surface layer of samples, depending on their processing modes and graphs of the distribution of residual stresses in the surface layer are also presented.
