The studies were performed on martensiticaging steel H8K18M14. As a result of the experiments, it was found that when grinding wheels made of materials such as electrocorundum, CBN (borazon) and diamond, a significant role is played by the values of the cutting force, which increase during processing.</p> <p>During the experiment it was found out: the cutting forces Py and Pz in the width of the allowable modes, which are most often used in circular and flat grinding, can reach the following values: with the structure of the wheel 26 come to values from 2.714N to 30.721 and with the structure of the wheel 40 come to values from 2.49N to 28.185N.</p> <p>Reducing the grain size of the wheel, let’s obtain the effect of increasing the energy costs of the grinding process, by increasing the magnitude of the cutting forces.</p> <p>If to compare the cutting forces that occur when grinding different wheels, it is possible to note the following: in comparison with electrocorundum wheels when using wheels with KNB cutting forces are reduced by 20-25 %, and when grinding with diamond wheels, the effect of cutting forces is reduced by 25 - 30 %. When grinding with highly porous wheels, the cutting force is 15-20 % higher than when grinding with wheels of normal porosity.</p> <p><strong>The area of practical use of research results-</strong>grinding technology for maraging steels.</p> <p><strong>Innovative technological product – </strong>relationship between processing modes and the magnitude of cutting forces when grinding maraging steels.</p> <p><strong>Scope of application of an innovative technological product-</strong>mechanical engineering technology</p&gt;}, number={4}, journal={ScienceRise}, author={Lebedev, Vladimir and Bespalova, Alla and Chumachenko, Tatiana and Omelchenko, Yevhen and Nikolaieva, Tatiana}, year={2021}, month={Aug.}, pages={11-16} }
