| Research Abstract |
An electrical discharge machining method makes a micro crater form by electrical discharge, and processing advances by repeating this phenomenon. In order to measure growth around crater fabrication, the circuit which detects contact was constituted. In addition, the Z-axis was taken as the drive by piezo. As a result, when crater fabrication was carried out, it became tens of micrometers growth in several milliseconds time. A short circuit occurs at a place unrelated to the present electrical discharge which is controlling the Z-axis by this growth phenomenon.
