Abstract
This report proposes a new constant-pressure magnetic abrasive finishing process to improve the workpiece form accuracy for precision machining of planar and curved workpieces, based on the machining principle of an internal magnetic field-assisted machining process using a magnetic machining jig. This new machining method is a process by which a constant pressure is applied to the magnetic pole of a conventional magnetic brush, and the constant pressure acts on the surface of the workpiece through the magnetic particle brush formed at the magnetic pole surface. Experiments were performed using the conventional magnetic abrasive finishing process and the newly proposed constant pressure magnetic abrasive finishing process to compare the deburring characteristics. A brass disk in which was drilled a hole was used as a workpiece. The results showed that burrs can be removed using this new plane magnetic abrasive finishing process, and this process is more useful than the conventional magnetic brush for improving the form accuracy of the workpiece.
