| Outline of Final Research Achievements |
In order to machine optical materials with higher accuracy and higher efficiency, the research on ultra-precision machining by assisting optical resonance and near-field light has been conducted. A novel micro-machining method performing ablation simultaneously has been successfully developed by assisting near-field light and focusing the light to micro-tool edge. From the result of micro end-milling test, it is clear that near-field light assisted machining makes cutting force lower, compared with general micro-machining.
