Abstract: The process of forming cuts by the planetary disk executive body of tunneling and cleaning combines is considered. The main technical solutions for the layout of the drive system of planetary-disk executive bodies in the most common "Ural" type waste-cleaning combines are shown. All known layouts of the water system of tunneling and cleaning combines with a planetary disk executive body assume relative rotation of the cutting discs and portable movement of the destructive organ from different electric motors, which has a significant effect on the formation of cuts on the open face surface. To determine the rational cutting parameters by the executive body, it is necessary to take into account the location of subsequent cuts relative to those previously left after the rotation of the executive body by 180 degrees. A method is proposed for calculating the percentage value of the displacement of the cuts relative to the previous ones after turning the executive body by 180 degrees. based on the data on the load of the drives of the planetary disk executive body of the VATUR software recording complex. The percentage value of the displacement of the incisors relative to those previously left is affected by the sliding of the drive electric motors of the executive body, depending on the magnitude of the operating load. The dependence of the ratio of the rotation frequency of the planetary disk executive body and the percentage value of the displacement of the cuts on the sliding value of the drive electric motors is established. The absence of the possibility of stable cutting along a new track using existing drive system layouts has been revealed.
