A novel wheel‐type vibration‐magnetorheological compound finishing method

Magnetorheological fnishing (MRF) is an important technique to achieve the surface precision of difcult-to-cut materials. In this paper, a wheel-type vibration-magnetorheological compound fnishing is proposed in terms of reducing the unidirectional scratch caused by the wheel-type magnetorheological fnishing tool and further improving the convergence rate of surface roughness. The vibration-magnetorheological coupling was realized through utilizing designed magnetorheological fnishing (MRF) wheel and a nonresonant vibrational device (NRVD). Through the theoretical and experimental analysis, the surface roughness has been verifed improved through increasing the normal and tangential forces, which are associated with introducing 2D vibration. The fow and viscoelastic models of the MRP fuid were established based on hydrodynamic lubrication and viscoelasticity theories. Finally, the feasibility of the proposed fnishing method was verifed by the results of improving surface roughness through designing reasonable processing experiment.
