: The authors carried out the experimental study of the influence of ultrasonic dressing of grinding wheels on the energy-force indicators of the grinding process. The study showed the degree of ultrasonic dressing influence on the cylindrical plunge grinding indicators in the automatic cycle of processing. The authors identified that ultrasonic dressing of grinding wheels with a dressing tool executing vibrations with the frequency of 22 kHz and the amplitude of 10…15 µm allows decreasing the supporting face of a grinding wheel texture 4 – 5 times through the increase of the abrasive grains quantity with the relatively sharp micro-edges and microcracks. It is shown, that the distinctive features of formation of the grinding wheel working surface texture during ultrasonic dressing ensure the reduction of cutting perpendicular force about by 30 % during the whole period of grinding wheel life as well as allows increasing the wheel life 1.5…2 times. It is noted that during the ultrasonic dressing, the abrasive grains break due to the repetitive impact loading creating numerous cutting edges and microcracks at the less dressing depth than after traditional dressing. In the result of interference of si-nusoidal trajectories of diamond points of a dressing tool, on a grinding wheel, a certain cammed texture forms, what de-creases the wheel bearing surface. The existence of two texture components explains the higher cutting power of a grinding tool compared to the traditional dressing.

: It is known that the most of breakdown fractures of the structures or machine parts are related either to the fatigue fracture or brittle fracture caused by the fatigue crack. For this reason, to reduce the possibility of the fatigue crack initiation and development, the expensive medium and highly alloyed steels are often used. This paper presents the com-parative analysis of the parameters of the fatigue fracture of samples of low alloyed 40H steel and medium alloyed 38H2N2MA steel. The fatigue tests of 10×15×80 mm prism samples made of 40H steel with the U - and V-shaped stress concentrators and of 38H2N2MA steel samples with the U-shaped stress concentrator were carried out on the Instron 8802 installation at the temperature of 20 °C according to the three -point bending scheme with ⱱ =10 Hz, R =0.1 and various Δ
目前已知，结构或机械零件的击穿断裂大多与疲劳断裂或疲劳裂纹引起的脆性断裂有关。因此，为了减少疲劳裂纹萌生和发展的可能性，通常采用昂贵的中合金钢和高合金钢。本文对低合金化40H钢和中合金化38H2N2MA钢试样的疲劳断裂参数进行了对比分析。在温度为20℃的Instron 8802安装装置上，按照ⱱ=10 Hz, R =0.1和各种Δ的三点弯曲方案，对带有U形和v形应力集中器的40H钢10×15×80 mm棱镜试样和带有U形应力集中器的38H2N2MA钢试样进行了疲劳试验
