A study on the micro hole machining of Al2O3 ceramics
$Al_2O_3$ 세라믹의 미세구멍 가공에 관한 연구
Abstract
This paper describes result of experiment of parameters affecting the micro hole drilling time, kind of assisting gas and it's pressure. The result reveals that parameter value of 0.08J, 20Hz, dwell time of 300 microseconds can be a good machining condition to make micro hole diameter range of 50-70
