In this study, a low melting temperature alloy, that is expected to generate larger than usual removal volume for each discharge, is used. Through observation of the craters generated on the low melting temperature alloy for each discharge condition, the mechanism of material removal is investigated. Single discharge experiments on the low melting temperature alloy using tungsten electrodes of 0.1mm diameter, were carried out in kerosene oil or de-ionized water. Double pulses continuous discharge experiments were also carried out. The discharge start timing of the second pulse was used as a variable. Observation of bubble behavior in the gap region was done using a high-speed camera. From results of these experiments, the mechanism of material removal in each single discharge are discussed.
