The problem of dynamic cutting stability when using multi-blade tools (MLIS) to improve the accuracy and quality of processing is relevant due to the difficulty of accounting for rod vibrations and the influence of blades. Loss of stability due to interaction with the footprint of the previous blade has been little studied. It is necessary to develop mathematical models to determine optimal cutting parameters and ensure the stability of the MLI system. The purpose of the model is to determine the optimal parameters to improve processing accuracy and minimize self-oscillation.

The model shows that the force inheritance between the cutting elements significantly affects the dynamics of the process, forming traces of vibrations on the surface. The hereditary parameters determined by the coefficient affect the cutting stability. The developed equations and structural model can be used to create digital models and virtual experiments to improve the quality of processing and reduce defects when using MLI.
