摘要：
Air diffuser openings are machined in hollow gas turbine blades. The blade is supported in alignment with a laser machining beam and rotatable around several perpendicular axes. It is simultaneously rotated about both axes whereby a substantially hourglass shape is machined out of the blade. The root of the hourglass shape may thereafter be enlarged.
