Study on the ELID grinding of YAG ceramic

Abstract

YAG ceramic is considered as the new generation of the high out-put laser material due to its excellent energy. The YAG ceramic chip using for the laser instrument must be fabricated with the very low surface roughness. In this experiment, ELID grinding on the YAG ceramic chip was carried out. Various experimental conditions were investigated in order to get the ground surface with very low roughness. Through the experiment, the ductile ground surface was obtained. The experimental conditions and the results were introduced in this paper.
