experimental investigation of magnetic abrasive polishing of paramagnetic workpieces

This study investigates the application of the magnetic abrasive polishing process for paramagnetic workpieces. a magnetic disc, which comprises six magnetic coils and is electrified with a three-phase ac current, is used to perform the experiments. in the experimental setup, various parameters including rotational speed of abrasive pins, quantity of abrasive pins, working gap, abrasive pins' dimensions, and process's time can be changed. changing the surface quality of these parameters is investigated. two kinds of workpieces with different mechanical properties are examined. it is observed that both increasing the rotational speed and using smaller pins improve the final surface quality; however, the rotational speed has a sharper effect. there are optimum abrasive pins quantity and working gap in which the best surface quality is obtained. the results are similar for the both selected materials.
