Abstract: Vibration finishing which is often applied to the metal surfaces recently is the finishing method using a disk-type finishing tool with movements of rotational and orbital motion [1]. However, an application of this finishing method and an evaluation of finished surfaces require skills and sensory examinations. This is because the relations between finishing conditions and quality of finished surfaces are not clear. In recent years, image processing methods for evaluating finished surface roughness and texture analysis were proposed [2 - 5]. However, quantitative evaluation has not been fully done.

Abstract: In the magnetic-field-assisted finishing, grinding powder mixed with iron powder is placed inside a part and vibration is applied to the part under magnetic field. Effects of the process on deburring of step-wise holes and internal roughness of brass square pipes were examined. Rotation was given to the pipes with step-wise holes, while the magnetic poles were vibrated. Axial vibration was given to the square pipes, while the magnetic poles were fixed. Burr formed by drilling at internal edges was effectively removed by the process. Inside roughness of the square pipe was successfully finished to 0.023 μm Ra.
