For the blisk polishing tool belt flapwheel, the surface morphology of the polishing tool was measured and modeled. The automatic zoom three-dimensional surface measuring instrument was used to scan the surface morphology of the P240 and P320 sampled belts to analyze and obtain characteristic parameters such as the distribution density and the height distribution of abrasive grains. Then, through the two-dimensional digital filtering technology and the Fourier transform method, a rough surface with a specified autocorrelation function was generated. By analyzing the flexible characteristics of the belt flapwheel, models were established for the surface morphology of the static and dynamic belt flapwheel respectively, and the surface morphology of the belt flapwheel under different conditions was obtained, which provided support for the formation mechanism of the workpiece surface polished by the belt flapwheel.
