Profile precision and stability of aeroengine blade has a direct influence on the global performance of aeroengine. Because of high machining difficulty and weak stiffness

profile precision and surface quality are very hard to meet the design requirements. So

many methods are developed and utilized to control the deformation of aeroengine blade. Based on the analysis of deformation mechanism and application characteristics

the deformation control methods and mechanism for machining aeroengine blade are classified. Meanwhile

different characteristics of deformation control methods are analyzed in depth. According to the structure

difficult-to-cut material characteristic and some processing problems of aeroengine blade

controlling the deformation caused by residual stress is the key point to reduce the profile errors of blade to be 20μm. Moreover

the high-speed helical cantilever grinding process using the super-hard abrasive wheel is effective in the finish machining aeroengine blade to control the integrated deformation.
