Background. A distinctive feature of the implementation of the centerless grinding method is the condition of power closure at the contact points of the treated surface and the elements of the technological system, compliance with which largely determines the stability of the processing process. Of decisive importance in ensuring this requirement are issues related to the establishment of the scheme of acting forces and the calculation of their values. Materials and methods. The sequence of developing dependencies for determining the components of forces and their values, taking into account the characteristics of the treated surface, equipment and tooling in the entire space of the working area, is presented. Results. A generalized model has been created for calculating the components of cutting forces and forces at the points of interaction of the workpiece with the leading circle and the plane of the support knife, the relationships between them and the factors affecting the processing process have been established. Conclusions. The models presented in the article make it possible to assign reasonable parameters for setting up equipment and determine rational processing modes to ensure the stability of the flow of the process of centerless grinding.
