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： Spark-erosion machining method and machine implementing a machining gap, a process regulator, a numerical control system, a Nominal Trajectory. The latter describes the movement of the tool electrode relative to the part as it ought to proceed if no disturbance were to occur during the machining. Information contained in the Nominal Trajectory is used to define at least two control vectors Vg, Vp which orient, within the coordinate system XYZ, two independent regulation movements. The first, or Gap Vector Vg, defines the direction in which a first regulation movement of the axes of the machine must be performed to maintain the removal of material. The second, or Position Vector Vp, defines the direction in which a second regulation movement of the axes of the machining machine must be performed to correct a tool electrode position error. The respective amplitudes of the regulation movements are calculated in real time by the process regulator.

摘要： The electrical discharge machining device comprises a first voltage/current source (U1) for discharge initiation connected to the tool electrode (F) and a workpiece electrode (P) forming the poles of a machining gap (G) and a second voltage/current source (U2) that can be disconnected by way of two switches (SW1, SW2). Capacitive elements (C1, C5) are mounted in series in the lines (10, 11) connecting the first source to the poles of the machining gap (G). In addition, these poles can be connected by a self-induction coil (Lm) mounted in series with an adjustable DC source (Sm). Thanks to these features, the energy of the eroding discharges can be significantly reduced in order to obtain a superfine surface finishing process of high quality, while at the same time precisely controlling the mean voltage across the terminals of the machining gap.
