Abstract
In this study, the relationship between the share stress by a magnetic functional fluid and the polished material's removal quantity was investigated on the precision processing of vertical tube inner wall utilizing a magnetic compound fluid. On the processing experiment, two kinds of tools consisted of one ring-shaped permanent magnet were used. And the shear stress to act on the each tool and the removal quantity were measured. From the experimental results, the correlation between them was clarified. It can be suggested that the processing pressure induced by the shear stress was related to the removal quantity.
