| Liquid-magnetic abrasive tool finishing is a kind of new technology on precise finishing. It is an innovative finishing technology that takes advantage of the theory of magnetorheological fluid. It is composed with magnetic particle, carrier, surfactant and abrasive particle. Liquid-magnetic abrasive tool is liquid condition at zero magnetic fields so that it can close around the complex surface of workpiece. On application of external magnetic fields, Liquid-magnetic abrasive tool prompt generates facies change from Newton fluid to plastic Bingham body. At the same time, it embeds the surface of workpiece like a molding abrasive disk. When the relative movement between workpeice and Liquid-magnetic abrasive tool happening, a portion of the part surface materials is removed.The dissertation investigate the physical property and working mechanism of Liquid-magnetic abrasive tool with adopting combination of theoretical analysis, experimental investigation and numerical calculation. |
