We have studied single discharge machining to low melting temperature(47℃) alloy. The purpose of this study is to make clear the crater generation process in single discharge machining. In this report, single discharge machining is carried out with kerosene oil and de-ionized water and air. In kerosene oil and de-ionized water, the cross section profile of the crater is near the one part of sphere shape. Under the negative electrode with over 200μs pulse duration in kerosene oil, the volume of the crater decrease. In de-ionized water and the negative electrode in kerosene oil, a lot of non-spherical debris are observed. From the observation of the craters and the debris of the low melting temperature alloy, the mechanism of the material removal is discussed.
