Abstract: As the power of new aero-engine increases and the structure becomes more complicated,greater demands are placed on the turbine blade.Rigid and tough materials are widely used in the turbine blade in order to increase the strength and stiffness of the blade.The thickness of blade is thinner and airflow is increasing accordingly.The stability of the aero-engine working in the high temperature and pressure condition can be achieved.The blade of aero-engine tends to be more rigid,precise and thinner,so it is necessary to study on the five-axis simultaneous machining technology of the blade.

Key words: blade, five-axis simultaneous, deformation
