The article describes the results of theoretical studies using 3D finite element modeling, which made it possible to determine the rational characteristics of diamond wheels on ceramic bonds. The influence of the parameters of the diamond-bearing layer on the change in its stress-strain state in the sintering zone of the diamond wheel has been studied. The results of finite element and microlevel 3D modeling of the sintering process of a ceramic-matrix diamond-containing composite are analyzed. The influence of the technological parameters of the process and the characteristics of the diamond wheel on the integrity of the grains during sintering was established, on the basis of which practical recommendations were given for the selection of diamond compositions with rational properties.
