FIELD: metal cutting. SUBSTANCE: method comprises steps of moving end tool by lines, rotating tool around its own axis and rotating tool around two additional axes inclined relative to tool axis in such a way that all axes are crossed in one point coincided with center of worked surface. In order to enhance efficiency of working process due to lowered cost of equipment and technological preparation stage, second additional axis is arranged along bisecting line of angle between first additional axis and tool axis. Angular rotation velocity values of tool relative to additional axes are selected according to given relation. EFFECT: enhanced efficiency. 4 dwg
