Outline of Final Research Achievements

This research deals with the development of an ultrasonic vibration assisted MCF (Magnetic Compound Fluid) polishing technology for final polishing. This paper describes the fabrication of an experimental apparatus composed mainly of an ultrasonic polishing unit, and the experimental investigation of its performance in surface polishing. In addition, investigation of ultrasonic vibration assisted MCF polishing under different applied methods of ultrasonic vibration was also conducted. The experimental results indicate that applying ultrasonic vibration to the workpiece improves the surface roughness and the material removal rate when the ultrasonic vibrations are changed. In addition, over the range of polishing conditions employed in this paper, the precision surface roughness and high material removal rate can be easily obtained on the acrylic plate by using an elliptical vibration is applied to the ultrasonic vibration.
