Abstract

Abstract: According to the new method of hydrodynamic suspension polishing, CFD software is used to simulate the polishing to obtain the distribution of fluid pressure and the velocity of the particles impacting on the work piece surface under different working conditions by the method of orthogonal design. The simulation results show that the rotational speed ω of the disc is the main factor affecting the dynamic pressure and the abrasive particle velocity, while the machining gap H is the secondary factor,and the least influence factor is the polishing liquid concentration φ. The optimal design parameters are: ω=1500 r/min, H=50 μm, φ=0.3. Under the combined parameters, the distribution of the fluid dynamic pressure gradient along the radial direction, the velocity field distribution of the workpiece is consistent with the velocity distribution of uniform circular motion, and the velocity can assure the polishing quality and efficiency.
