    • 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 (4) 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 (Uign) is applied on the work gap (4) in order to initiate a discharge within the work gap and to measure the corresponding ignition delay time (TD). The ignition voltage (Uign) and/or the gap width are adjusted such that the ignition delay time (TD) is smaller than an oscillation time of the working electrode oscillating within the work gap (4) due to the electrostatic attraction force and the mechanical restoring force.
    • 本发明涉及一种借助于工作电极对工件进行放电加工的装置和方法。 工作脉冲序列施加在工作电极和工件之间的工作间隙(4)上。 工作脉冲包括用于将材料从工件上侵蚀的腐蚀脉冲和测量在工作间隙(4)上施加点火电压(Uign)的脉冲,以便启动工作间隙内的放电并测量相应的点火延迟 时间(TD)。 调整点火电压(Uign)和/或间隙宽度,使得点火延迟时间(TD)小于工作电极在工作间隙(4)内由于静电吸引力而振动的振荡时间 恢复力。
