Study on the finishing mechanism of fluid magnetic abrasive

The Fluid Magnetic Abrasive (FMA) is a new type of precision finishing abrasives that has the capability of processing complex part to a quite low surface roughness. The microscopic and macroscopic finishing mechanism of FMA is investigated in this paper for the first time. A process models is derived to elucidate the mechanism and material removal rate in FMA and some key parameters in finishing process that may affect the finishing efficiency and the final surface roughness are analysed theoretically. The experimental results are also discussed in this paper.
