The final machining (or finishing) of precision parts with high accuracy level is making the application of abrasive finishing technologies increasingly important. Magnetic abrasive finishing (MAF) is a new advanced finishing process used for fine finishing of extremely hard materials. It is employed for finishing of metals and non-metals. This paper focuses on the modeling and simulation for the prediction of surface roughness in plane magnetic abrasive finishing. A finite element based model is developed to find the magnetic potential distribution in gap between tool and workpiece. Further, magnetic potential is used to evaluate machining pressure, material removal and finally surface roughness of the workpiece surface. The simulation results are confirmed compared with the experimental results available in the literature. The simulated workpiece surface roughness shows features which are similar in nature to the experimental results.
