The invention discloses a method for generating a mixed path of rough-semifine-fine milling of an integrated impeller blade with large extension and weak rigidity. The method comprises steps of generating a rough milling cutter locus source file and a fine milling cutter locus source file of the blade according to the geometrical shape and the technological parameters of the integrated impeller blade with large extension and weak rigidity; extracting a K-channel cutting path close to the blade from the generated rough milling cutter locus source file and rearranging the K-channel cutting path in order to enable the rough mill cutter path to process around the blade; extracting a fine milling part and a semifine milling part of the cutter from the generated fine milling cutter path file in order to generate a semifine-fine milling cutter path file; performing variable feeding operation on a new rough milling cutter path file and the generated semifine-fine milling cutter path file; layering the acquired rough
