Enhanced magnetic abrasive polishing of non-ferrous metals utilizing a permanent magnet

This study aimed to improve the magnetic flux density in magnetic abrasive polishing process for non-ferrous materials, specially focused on magnesium. The magnetic flux density for ferrous and non-ferrous materials was simulated. To increase the magnetic flux density for non-ferrous materials, a practical method that installed a permanent magnet at the opposite side of the workpiece to be machined was proposed and evaluated by computer simulation and experimental verification. For determining a dominant process factor and optimal conditions of the magnetic abrasive polishing for a thin magnesium plate as a case study, the design of experimental method was adopted.
