【 摘 要 】

The article discusses the process of shaping holes with three-bladed counterboring tools, taking into account the inaccuracies of sharpening the cutting part and feed fluctuations arising due to axial beats of the machine spindle. The shaping schemes have been constructed, equations have been derived for calculating the areas of cut-off allowance sections for which the radial cutting forces are calculated. A comparison obtained by mathematical dependencies and in the scale model in a three-dimensional modeling system for the values of the cut section areas was made. Vector sum of radial cutting forces allows to determine the point's coordinates of the resulting surface, which can determine the parameters of machining accuracy.
