Abstract
In this study, a magnetic pole vibration device that uses a proximity sensor for magnetic abrasive finishing equipment using a permanent magnet was developed, and the performance of this system was proved, focusing on how the surface roughness of STS 304 pipes is affected by the magnetic pole arrangement. The results of this study confirm that the resulting magnetic fields of different magnetic pole arrangements change the behavior of the magnetic abrasive mixture, thus impacting the abrasion effect. Among the four different pole arrangements investigated, the M-S-N magnetic pole arrangement provides the best surface finish. A mixture of iron particles and magnetic abrasive materials in a 3 to 1 ratio is found to be the most advantageous in terms of surface roughness and material removal rate. In addition, the wet processing, in which light oil is added to the magnetic abrasion mixture, is more effective than the dry processing. Finally, the effect of the spindle speed was also investigated for speeds from 200 to 1,400 rpm. At 1,400 rpm, the surface roughness shows approximately 76.1% improvement over that at 200 rpm.
