Abstract

In the current paper application of magnetic abrasive polishing process, on paramagnetic workpieces is investigated. A magnetic disc which comprises of six magnetic coils and is electrified with 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 this parameters surface quality 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 final surface quality but 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.
