"A number of machine parts are provided with design notches for the mounting of lock ring, position of bearing, and cross over sub of diameters etc. These elements significantly affect the durability of machines parts and their influence is inherently implemented into their design. The question is machining itself, particularly ambient surface finishing and intrinsic notch element. The changes and behaviour of machined surface form also very interesting part of paper and particularly under load. A number of new findings concerning the influence of machining on durability of machine parts both under dynamic load and of the cyclic tensile and bending at rotation were discovered in this research. The findings are important for further development, mainly related to car and aviation industries. The best results were achieved at the turned both surface and notch by means of sintered carbide tip for the load of cyclic tensile (fig.3). Significantly lower notch durability is reached at the combinations of grinding and turning just as grinding application for the notch surround and own notch (fig.3, 4, 5). The dependence of load cycle number and surface roughness Ra was found on the basis of experiment (fig.6, 7) and for the ground surfaces then formula (1). The rotation bending simulates the actual dynamical load of notch for the rotary machine parts. The notches making by means of turning with SC tip (fig.9) show very low durability at the fine grinding of notch surround ( grain size 150). The ground notches at the turning of notch surround by means of SC tip show a high durability of machine part, pertinently also the ground notch surround by means of SG fine grains or medium sized grains at the higher grinding speed 45 m.s-1 (fig.10, 11)."@en . . . .
