Automatic polishing method of high-temperature alloy blade

The invention relates to an automatic polishing method of a high-temperature alloy blade. A blade 3D model and a blade rough blank model are imported through numerical control machining software provided with a robot numerical control machining hanging piece; the knife path of blade grinding is generated through the numerical control machining software according to the machining process of a belt sander; and post-treatment is conducted through the robot numerical control machining hanging piece to switch the machining knife path into the blade machining procedure of an ABB robot, and joints and a rotating shaft of the robot are guided to move and feed. A curved face blade is machined through a mechanical arm on the basis of manual polishing, the automation degree is high, operation is convenient, the purposes of labor saving and cost saving are achieved, meanwhile, the needed precision and smoothness requirements can be guaranteed, in addition, manual machining is replaced with automatic machining, and thus h
