The model of oscillation treatment of removable many-sided plates of toolpiece is developed with the central openings and the use of cassette drum, freely placed in a working chamber. Dependences, allowing to determine time of treatment for the receipt of the required radius of rounding off of cuttings edges of removable many-sided plates at the proper modes and terms of oscillation treatment, are got, or to set these parameters for a concrete machine-tool, providing minimum time of treatment.
