Characteristics of Material Removal on Micro Processing for Inner Surface of Cylinder Utilizing a Magnetic Compound Fluid

Abstract

　In this study, the relationship between material removal and shear stress from fluid, and the processing pressure on micro-ordered precision processing for inner surface of cylinder utilizing a magnetic compound fluid were investigated. The amount of processing has a local maximum and a local minimum at increasing rotational speed of permanent magnet tool. This cause was discussed with an absorption force between magnetic particles and a circumference force of magnetic cluster. In addition, the amount of processing was clarified to be correlated to the shear stress and the processing pressure respectively. It was also clarified that the characteristics of processing amount and processing pressure were divided into low and high rotational speed regions of the tool.
