Abstract: The magnetic abrasive finishing (MAF) process which was introduced during the late 1940s has emerged as an important non-traditional metal finishing process. The process has found applications in a wide range of fields such as aerospace, medical, electronics, precision dies and moulds as a part of their manufacturing activities. Magnetic abrasive grit size, magnetic field intensity, magnet & workpiece gap, relative speed between workpiece & magnet, vibration of workpiece/magnet are the principal parameters that control the surface characteristics. MAF is the process that is being developed for efficient & precision finishing upto nanolevel of cylindrical or flat workpieces made of hard to machine materials. This review provides an insight into the fundamental parameters and creates a better understanding of this finishing process, with the objective of helping in the selection of optimum machining parameters for finishing of varied workpieces in practice.

Series Of Experiments

The magnetic abrasive finishing (MAF) process is an ultra-precision surface finishing technology. In order to further improve the finishing efficiency and continuity, a magnetic abrasive finishing process using the circulatory system to renew magnetic abrasive slurry was proposed. This study investigated the mechanism of the compound magnetic finishing fluid in the process using the conveyor belt as the carrier to complete the circulation and finishing through simulation and theoretical analysis. The influence of the different distribution states of the magnetic finishing fluid in the conveyor belt and the finishing area on the finishing characteristics is observed and analyzed, in addition to a series of experiments to explore the feasibility of finishing polychlorotrifluoroethylene resin plate through this process. Experimental results show that as the working gap decreases, the distribution width of compound magnetic finishing fluid on the conveyor belt becomes larger, and the distribution of the points of action on the workpiece in the finishing area is significantly different and the area increases, and obtains a higher finishing force and finishing efficiency. In this study, the surface roughness of polychlorotrifluoroethylene resin plate was improved from 274 nm Ra to 34 nm Ra within 15 min.

In this paper, a new plane magnetic abrasive finishing process by using alternating magnetic field is proposed to improve the efficiency and surface precision. In alternating magnetic field, the forced direction of magnetic particles is changing. Therefore, magnetic particles could produce the up and down movement, which promote the scatter of magnetic particles , improve the roll of abrasive particles and enhance the utilization of abrasive. In order to know well the magnetic intensity distribution in processing area, measured the magnetic flux density. Finishing force is important to understand the mechanism of material removal, investigated to the finishing force and contrasted to the movement changes of magnetic particles in water-soluble finishing fluid and oily finishing fluid. A set of experimental devices have been designed to realize surface polishing on C2801 brass plate, the results proved the feasibility of this method, which can improve the workpiece surface quality.
