Abstract：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.
