Abstract
Magnetic field assisted machining method uses flexible particle-brushes that consist of ferromagnetic particles. It is processed using particle-brush and abrasives slurry. Ferromagnetic particles are connected along the line of magnetic force, and form a particle-brush. In magnetic field assisted machining, basic research associated with the particle-brush is crucial for expansion and development of magnetic polishing. However, many items relating to details of machining characteristics are still unknown. In this study, smaller diameter ferromagnetic particles are mixed with larger diameter ferromagnetic particles to form the particle-brush to be used for polishing. It has been clarified that the particle-brush containing smaller diameter ferromagnetic particles is effective in machining the workpiece with a groove.
