| Outline of Final Research Achievements |
In this study, processing technique of super precision with high quality by utilizing a magnetic functional fluid on a nano-meter ordered flat surface and a sub-micron ordered shape precision was developed for the inner surface of a short or long tube that is difficult to cut.
As specific results, the processing characteristics on the inner tube walls were clarified as the characteristics of magnetic field distribution on the micro-processing, the one of magnetic clusters on the micro-processing and the one of correlation between the removal quantity and the shear stress by the ring-shaped permanent magnet. Moreover, it was confirmed that the material quantity follows as Preston’s law. Using those obtained basic data, the examination of the equipment of the nano-processing was applied for an inner surface of a long tube. And the processing characteristics of the long inner tube wall were investigated.
