Abstract

The effect of pulse current and tool immersion depth on gas film formation and its consequences on machining quality in the pulse electrochemical discharge machining (PECDM) of glass-fiber epoxy reinforced composite are studied. The frequency and duty cycle of the pulse current were controlled for discharging at no more than single spark per cycle. As compared to ECDM with DC current, the PECDM results in smaller hole diameter and smaller heat affected zone (HAZ). Also, lower tool immersion depth results in thinner gas film and smaller HAZ in the workpiece.
