キーワード	ultra-precision / fluid jet polishing / ultrasonic cavitation / material removal / surface finishing / optical surfaces / medical surfaces
研究成果の概要	The mechanism of material removal boosting in ultrasonic fluid jet polishing was investigated. Macro-scale fluid vibrations were found to cause increased erosive action by abrasive particles. The fundamental understanding of this novel process opens the door to optical and medical applications.
自由記述の分野	マイクロエンジニアリング（工学）
研究成果の学術的意義や社会的意義	Fluid jet polishing is a very flexible method for polishing small and complex surfaces, such as aspheric lenses for smartphones or dental implants, but was however inefficient. With this research, the productivity of FJP was greatly enhanced, which will benefit consummers of such important products.
