Flexible polishing technology is widely used in the precision machining of aero-engine blisk blades.It has become one of the important research contents of flexible polishing technology to systematically study the flexible polishing process and understand the connotation of the microscopic morphology of the polished surface.In this pa-per,the flapwheel is used as a flexible abrasive tool,and the spatial kinematics model for the abrasive grains on the surface of the flapwheel and the geometric interference model for the abrasive grains and workpiece are established by transforming the spatial geometric coordinates.Based on the surface topography model for the abrasive tool,MATLAB software was used to simulate the micro topography generation process of the flexible polishing surface with flapwheel as abrasive tool,and the three-dimensional topography of the workpiece surface and its influence law under different process parameters were obtained.The polishing experimental results verified the simulation algorithm correctness and effectiveness.
