FIELD: machine building.
SUBSTANCE: procedure is implemented at machines with numeric programmed control and consists in rough processing in form of cutting lots of uniform width in radial direction and in finish treatment by milling channel section of blades under modes conditioned by value of allowable deformation of processed surface. Thickness of line at finish milling does not exceed length of a cutting section of a tool coinciding with generatrix of blade profile. Cut in by height of profile is carried out gradually from a top of the blade to radius of transition into a hub. Also, the cutter is transferred along a closed trajectory equidistant to profile of a suction face and pan of blade in plane of line.
EFFECT: upgraded accuracy.
