FIELD: metallurgy.
SUBSTANCE: method relates to milling of details made of hard-to-cut materials, first of all milling of used rotor in gas turbine with set of implemented with it blades by means of milling cutter movement by at least one predetermined path. Additionally to path or to each path of milling cutter it is defined at least one corresponding to surfaces or edges by at least on side surface collision contour, which or each of which relates herewith to manufactured detail, and it is controlled position and/or orientation of milling cutter relative to collision contour or each collision contour, changing the position and/or orientation of milling cutter and/or forming message about the mistake, is milling cutter break at least one of collision contour.
EFFECT: reliability growth of treatment process.
