The effect of different abrasive configurations on surface roughness and material removal. Furthermore, the subsequent development uses the rotating magnetic pole to drive the rotation of the magnetic abrasive to investigate the influence of the shape and rotational speed of the magnetic pole on the surface roughness and the amount of material removed, but the surface material removal ability and surface precision, etc., which are difficult to be processed, such as a spiral curved surface of a complicated shape.
