controlled efficiency of drilling with a high intensity beam

碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 101 === Drilling with a high intensity energy beam can beincapable if the keyhole induced is collapsed. In this work, we identify the conditions for the keyhole collapse during high power density beam drilling from fundamental principles of thermal physics. The app...
