Understanding flexible abrasive brush behavior for double disk magnetic abrasive finishing based on force signature

Abstract

The Double disk magnetic abrasive finishing process (DDMAF) poses better finishing characteristics while finishing paramagnetic thin work piece, when compared to plain magnetic abrasive finishing. This is due to the significant change in the behaviour of the flexible magnetic abrasive brush (FMAB) formed in two cases under similar conditions. Observing and comparing the behaviour of FMAB in action visually is a difficult task. However, FMAB average behaviour can be understood by observing the force signature. Thus present work aims at developing a setup that can be used to capture force signature for the two cases and then understand the FMAB behaviour. The present work present the FMAB force signature obtained while performing finishing with MAF with single disk and double disk. The force signature and the basic magnetic principle have been used to understand the FMAB behaviour and thus understand implications on the finishing process.
