Glass Polishing Technology Using MR Fluids

Based on the properties that yield stress would increase as an applied magnetic field increased, magnetorheological (MR) fluids were used on glass polishing. MR fluids were considered as a polishing fluid whose rigidity could be adjusted. Therefore, different polishing effects could be achieved by adjusting the strength of magnetic field. The mathematical model of this technology was established and based on this model, the effects of several parameters on MR fluids polishing were investigated. The removal rate was proportional to the strength of magnetic field and the velocity of MR fluids and inversely proportional to the distance between the part and the moving wall. The agreement between mathematical model and experimental results was very satisfactory.
