A study of machining chracteristics effecting on laser focusing position in the ceramics microhole machining

세리믹 미세 구멍가공에서의 레이저 초점위치가 미치는 가공특성 연구

[ $Al_[2}O_{3}$ ] ceramics are generally used as components in processing equipment, devices or machinery. But it's difficult to machining as being machanical because $Al_[2}O_{3}$ ceramics are brittle materials. This study described a basic study of the input parameters effect on the dimension of the microhole at the $Al_[2}O_{3}$ ceramics using Nd:YAG laser. Major input parameters are peak power, pulse frequency and pulse duration in the laser microhole machining of $Al_[2}O_{3}$ ceramics. We will get a smaller microhole and diameter rate by an appropriate peak power, pulse duration.
