Abstract
The invention relates to a device and a method for electrical discharge machining of a work piece by means of a working electrode. A sequence of working pulses is applied on the work gap between the working electrode and the work piece. The working pulses comprise eroding pulses for eroding material off the work piece and measuring pulses during which an ignition voltage is applied on the work gap in order to initiate a discharge within the work gap and to measure the corresponding, ignition delay time. The ignition voltage and/or the gap width are adjusted such that the ignition delay time is smaller than an oscillation time of the working electrode oscillating within the work gap due to the electrostatic attraction force and the mechanical restoring force.
