FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to reconditioning of turbomachine compressor blades. Blade radial end has cat's tongue, its radial divergence is smaller than preset nominal radial divergence. Blade edge is displaced between two rollers with rectilinear generating lines spaced apart through distance smaller than depth of said cat's tongue along the chord connecting its rib of attack with trailing edge. Note here that said cat's tongue is elongated so that its radial elongation exceeds said initial nominal divergence.
EFFECT: enhanced performances.
