Abstract
In this study, the machining characteristics and the removal mechanism in EDM for one directional CFRP was discussed in order to investigate the influence of carbon fiber direction to machining direction and to attain high performance EDM. Then EDM characteristics with two different combinations of machining direction and carbon fiber direction were compared. Experimental results clarified that the material removal mechanism in the EDM for one directional CFRP when the machining direction is perpendicular to the fiber direction is different from that in parallel machining. Therefore, efficient EDM for CFRP is possible by selecting appropriate machining direction to fiber direction.
