Study on Corrective Abrasive Finishing for Workpiece Surface by Using Magnetic Abrasive Finishing Processes

Abstract

In order to improve the plane quality of the workpiece shape accuracy, a correction abrasive finishing method is proposed. This method is used to achieve the effect of correcting the workpiece surface by changing the finishing conditions of different areas according to the profile of the initial surface, such as feed speed. In previous research, the feasibility and effectiveness of this method were proven. In this research, a theoretical analysis of this method was carried out and the extension of this method to the processing of larger planes was studied. Through a series of experiments on an aluminum plate (A5052), it was proven that the shape accuracy of the workpiece surface can be effectively corrected by accurately controlling the feed speed. The experimental results showed that the extreme difference of the workpiece can be reduced from 4.81 µm to 2.65 µm within the processed area of 30 mm by 10 mm.
