Abstract
Blisk is a new integrated structure of blades and disk actually used in the aero-engine of high thrust-weight ratio. Based on the study of the state-of-the-art of the blisk manufacturing technology worldwide, a convenient manufacturing process and key technique of 5-axis NC machining are proposed in this paper, Such novelties include analyses of blisk-tunnel feature and partition of manufacturing area, determination of optimal orientation of cutter axis and its refinement, efficient rough-cutting of the tunnel, high-precision shaping, control of blisk distortion and vibration reduction of cutter and blade. Preliminary results of cutting test verify the validity of the techniques mentioned above.
