Abstract:In modern aero-engine manufacturing, high quality and high efficiency are simultaneously required for gas holes machining in turbine blade. Solutions and application results of multi-station electro stream machining technology is described, including the design of multi-station layout and equipment, the technology of blade positioning and automatic detection, the automatic setting of machining gaps and the technology of precise alignment and penetration detection. Through the automatic alignment and detection of blade, correcting the deviation of blade profile is realized. Through the replaced probe, the problem of determining the initial clearance is solved. By monitoring the processing fluid, the automatic transposition machining after penetration is realized.
