Abstract

This report deals with the machining performance of electro-chemical discharge machining (ECDM) with isolated multiple electrodes (divided power). Holes were machined by ECDM on glass. Their shapes were observed and compared with those with multiple electrodes connected electrically in parallel (equi-potential) and a single electrode. Cracks are frequently generated on the hole entrance by heat expansion in the equi-potential power and single electrode. Then they originate bases of protrusions by erosion. Eventually, a protrusion is formed. Because bubbles collapse during intervals in the divided power, hole diameter is not enlarged.
