Modeling bulk modulus of abrasive cloth wheel and polished surface roughness for polishing blade with abrasive cloth wheel

The blisk surface roughness has a significant impact on its fatigue strength and service life. It is very meaningful to study the influence factors of blisk surface roughness. In this paper, a calculation model for the bulk modulus of abrasive cloth wheel is deduced, the values of bulk modulus of abrasive cloth wheel corresponding to different process parameters are obtained by experiment, and a mathematical model of polished surface roughness about bulk modulus of abrasive cloth wheel is established. By verification, it is found that the model of polished surface roughness can accurately predict the blade surface roughness after polishing. The model has guiding significance for improving polishing process and machining quality.
