摘要： 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.

摘要： The invention relates to a method and a generator for generating a time sequence of discharge pulses for EDM machining wherein a pulse capacitor (22) for generating the discharge pulse is charged with a charging voltage (U_chrg) and then discharged into the spark gap. The pulse capacitor (22) after being discharged is recharged with a charging voltage (U_chrg) having the same polarity as that of the residual voltage (U_end) remaining at the pulse capacitor (22) after its discharge. Thereafter, the pulse capacitor (22) is discharged with a discharge pulse into the spark gap, wherein the polarity of the discharge pulse is independent of the polarity of the charging voltage (U_chrg) at the pulse capacitor (22) after its recharge.

摘要： The invention relates to a method and a generator for generating a time sequence of discharge pulses separated from each other by pulse pauses for electrical discharge machining. At least two pulse capacitors are discharged each in the form of a partial pulse into the spark gap for forming together a discharge pulse. A discharge pulse having a predetermined waveform is selected from a plurality of discharge pulses having differing predetermined waveforms. The discharge of the at least two pulse capacitors is controlled such that the selected discharge pulse is generated with the predetermined waveform.

摘要： The invention relates to a method and generator for generating a time sequence of EDM pulses having a predefined ignition voltage for electrical discharge machining. An AC voltage is generated from a DC voltage, furnished by a bipolar current source. The AC voltage is applied to an isolating transformer disposed between the bipolar current source and the spark gap. A first pulse capacitor is charged by the bipolar current source to a voltage corresponding to the ignition voltage. The ignition voltage provided by the isolating transformer is switched with a selected polarity to the spark gap.
