    摘要: An apparatus for measuring and/or controlling the tension in a ribbon or wire-type electrode of an electric discharge machine in which the ribbon or wire-type electrode is passed around a rotatable roller which is in operative engagement with a sensor. The roller is adapted to be driven in rotation by a motor or to be retarded by a brake. A support member for the roller and the motor or for the roller and the brake accommodates the weight of the roller and the motor or of the roller and the brake so that no load caused by the motor or the brake plus the roller acts in the direction of the tensile stress of the electrode. Any movement of the support means can be detected by a sensor, and the magnitude of the tension can be derived by a control unit from the output signal of the sensor. In operation, the control unit determines the tension on the wire and causes the unit to either increase or decrease the resistance caused by the roller.

    摘要: A pulse generator for spark-erosive metal working contains a charge regulator circuit for charging a storage capacitor. A storage capacitor is sinusoidally discharged across a switching device to a spark gap. Charging always occurs in a defined manner independently of the preceding pulses, so that uniform pulses can be generated. The storage capacitor is charged with an energy excess of required for discharge and the energy still remaining after spark discharge is recovered in a d.c. voltage source. The switching device (3) is non-conductive only when the discharge current has substantially decayed.

    摘要: A control device for controlling a machine tool includes at least one memory for storing control data characterizing the instantaneous operating state of the machine tool during machining and a memory management device for managing the control data such that machining can be resumed after an interruption. The control data is separated into dynamic control data and static control data. The method for controlling a machine tool uses the control device and stores the static and dynamic control data in the memory. As a workpiece is machined, the instantaneous operating state of the machine tool is continuously stored so that machining can be resumed after an interruption.

    摘要: To eliminate short-circuits between a countersink electrode and a workpiece during countersink erosion, when a short-circuit occurs, the countersink electrode is initially moved back by a predetermined path length (.delta.) along the previously travelled path from a first locus (P.sub.K) at which the short-circuit occurred to a second locus or intermediate point (P.sub.R) and it is established at that location whether there is still a short-circuit. If this is the case, the countersink electrode is moved in an upwardly sloping manner along a second path (R), which has a first angle (.alpha.) with respect to the working plane (AE) and has a movement component (R.sub.1) having a second angle (.beta.) with respect to a surface normal to the short-circuit or intermediate point (P.sub.K or P.sub.R). All the parameters (.alpha.,.beta.,.delta.,.vertline.R.vertline.) can be freely preselected and are variable during erosion.
