The proposed method of calculation made with the setpoint wane proved its effectiveness was tested and showed the following results. Volumetric output of lumbers with a blunt wane obtained by the method of cutting breakup increase compared with edging materials obtained in the same way cutting, by 7 %, that is 1.13 times. Volumetric output edged lumbers blunt wane when cutting with squaring increase by 14.17 %, that is 1.27 times. Volumetric output edged lumbers blunt wane obtained lumber-breakup means cutting increases in comparison with breakup method of cutting to 7.17 %, that is 1.085 times.
