N2 - To investigate the material removal mechanism in complex curved surface polishing with ABFW, it was assumed that the distribution of abrasive grain protrusion heights was normal distribution. The distribution model of polishing pressure between ABFW and blade was obtained based on Hertz contact theory. The force analysis of a single abrasive grain was carried out based on the elastic-plastic contact theory, and then the cutting depth model of the abrasive grain was established combined the height distribution function. Thus, the material removal volume of single abrasive grain was determined by synthesizing the spindle speed, feed speed and the shape of abrasive grain cutting groove, and the material removal depth model was established by integrating along the polishing trajectory. The experimental results show that the maximum deviation and average deviation between the predicted values and the experimental ones of material removal depth arc 4.85% and 2.95%, respectively, which verifies the correctness and effectiveness of the established model.
