Mechanical properties and polishing performance of force rheological polishing slurry under vibration

Abstract To explore the influence of vibration on the rheological properties and polishing effectiveness of slurry in vibration-assisted force rheological polishing process, the changes in forces on the vibrating plate under different vibration parameters are simulated using FLUENT software. The simulation results show a similar trend to the experimental results, indicating that the pressure on the workpiece surface under vibration is positively correlated with the amplitude and frequency. The apparent morphology of the slurry under vibration is observed, the slurry undergoes a transition from liquid-like to solid-like state under vibration. The effect of different amplitudes and frequencies on the polishing of stainless steel sheet is investigated. When the polishing speed of 40 rpm, the amplitude of 0.35 mm, and the frequency of 80 Hz, the surface roughness Sa of the workpiece decreases from (80 ± 10) nm to (7.1 ± 0.9) nm after 30 minutes of processing, with a material removal rate of 68 nm min⁻ ¹.
