Abstract: The fluid magnetic abrasives (FMA) are a new type of precision finishing abrasives, which can be used to finish the work-pieces with intricate or complex shape to a quite low surface roughness value. As a key parameter, the material removal rate has a great impact on the finishing capabilities and the final surface roughness. In order to get a better understand of FMA removal mechanism, the numerical analyses was used to simulate the shearing stress field and velocity distribution. The experimental results are discussed as well in this paper.

Abstract: The fluid magnetic abrasives (FMA) are a new type of precision finishing abrasives, which can be used to finish the parts with intricate or complex shape to a quite low surface roughness value. As a key parameter, the magnetic saturation flux density has a great impact on the design of finishing devices and the control of finishing process. In order to measure the magnetic flux density and determine the magnetization curve of FMA, a new apparatus has been developed. The measuring mechanism and the experimental apparatus are presented. The experimental results are discussed as well in this paper.
