FIELD: engines.
SUBSTANCE: invention relates to aircraft engine building, particularly, to gas turbine engines bladed disks manufacturing technology, preferably having geometrically-complex blades. Method involves cutting of grooves, treatment of back, trough and bottom of vane channels in one process cycle with one cutting tool. Tool performs straight-line movement along three axes of three-dimensional coordinate system and turning around said axes. During processing changing of diameter cutting tool cutting part, formed by outer and inner cutting edges, by value, determined by processed surfaces curvature, by cutting elements reciprocation in radial direction.
EFFECT: increasing accuracy and efficiency due to reducing number of passes.
