Dynamic prediction of the shape of MRF removal function

The dynamic prediction method is proposed to calculate the shape of magnetorheological finishing (MRF) removal function. After the establishment of transition mechanism of the shape of removal function, numerical analysis is performed to simplify this mechanism and hence resulting in the rapid prediction method for common MRF process configurations. The result indicates that, for most MRF settings, the variations of length and width change linearly with the variation of immersion depth, exhibiting coefficients of determination higher than 95%. Among the 49 prediction results, the relative errors for predictions of length range from -4.52% to 5.51% and the same figure for width predictions fluctuates from -7.2% to 6.63%. (authors)
