Abstract: This keynote paper aims at introducing applications of ultrasonic radiation force in industry. The chosen focus is to understand how to use it. Since the phenomenon of acoustic levitation can reflect the exciting of ultrasonic radiation force directly. The paper starts with an analysis on the tungsten ball floating on a sound field and ultrasonic micro-manipulation study in micro Electronic Mechanical System (MEMS). And ultrasound has been successfully used to degrade wastewater as its cavitation. At the same time, different kinds of micro-ultrasonic machining were used to show how exciting machining and ultrasonic radiation combined. A view from the authors and the final Conclusions show future applications of ultrasonic radiation force.

Abstract: This paper give some literatures for the technology of fluid polishing. Methods of fluid polishing using for optics curved surface, ultra-smooth plane and inner surface of non-circular curved surface. Each method is explained by above classifications, and some domestic cases which can produce ultra-smooth surface in different conditions, parts and technical parameters is listed and evaluated.
