FIELD: plastic working of metals, namely manufacture of blades of gas-turbine engines of compressors and turbines.
SUBSTANCE: method comprises steps of determining mean cross section of flat portion of blade with the same angle difference values of setting profile of root and peripheral cross sections; placing blade blank in attachment and fixing it along lock in such a way that chord of mean cross section is parallel to plane of milling blade. Straight line joining centers of maximum thickness of profile of root and peripheral cross sections is to be parallel relative to plane normal to axes of rolls of mill for further milling flat portion of blade.
EFFECT: possibility for making blades whose axis does not coincide with axis of their flat portion.
