| Summary: | 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.
