Abstract

A curved-hole drilling method by EDM using a metal ball electrode suspended with a thin leading part from the head of an electrical discharge machine has been proposed. This report discussed the effects of the leading part structure and metal ball size on the machining characteristics. Experimental results showed that servo voltage was a dominant factor for stable machining. Furthermore, various types of curved-holes were attempted by varying the tilting angle and direction of workpiece during the process.
