Abstract
As the heart of the aircraft, aircraft engine is the decisive factors of aircraft performance. The turbofan engine technology is in the forward position of aero engine, and has become the main power of fighter and civil aircraft. In order to improve the processing efficiency of the aero engine fan blades, a high-efficiency and energy-saving technology was given to replace the traditional processing methods. The paper analyzed and researched the problems which appeared in the machining process of the aero-engine, and the high-efficiency and energy-saving methods was summarized which would become the technical guidance of high efficiency machining of the aero engine fan blades.
