마이크로 공구를 이용한 미세구멍가공기술

ll as their high precision is required. In addition, as the national competitiveness is increasingly affected by the development of the micro parts through micro machining technology, the study of the micro machining technology is being conducted in many countries. The goal of this study is to fabricate micro tools under the size of 20mm and to machine micro holes using them. The fabrication is done by grinding and the application of ELID to the grinding wheel. The surface roughness of the micro tools is measured to evaluate the study.
