Executive Summary :

The proposed project aims to develop a magnetically assisted finishing process that allows for the variation of abrasive in the working gap or cutting edges in the finishing zone. The abrasive particles are supplied externally through a slurry in the finishing zone. The project introduces a disc-shaped magnet as a tool, allowing for a small contact area with the workpiece surface, allowing for finishing of external workpiece surfaces of varying curvature. The proposed setup introduces abrasive from an external source in the finishing zone, or the number of cutting edges can be varied. Previously, magnetic abrasive particles form the flexible magnetic abrasive brush (FMAB), but the presence of non-magnetic abrasive particles reduces the strength and rigidity of the FMAB. The proposed process does not restrict the number of abrasive particles in the finishing zone. During MAF, the temperature of the workpiece surface increases due to the abrasion action of the abrasive particles. The proposed setup provides abrasive particles mixed with fluid in the finishing zone, acting as a coolant to reduce sub-surface damage. The proposed process ensures the supply of fresh cutting in the finishing zone and ensures true randomness of the process by ensuring the abrasive particles follow the same trajectory repeatedly.
