  • Method and apparatus for controlling an electric discharge machining process
    Patent number: 8395069
    Abstract: A method for controlling an electric discharge machining process, wherein a tool electrode is moved relatively to a workpiece with a working gap distance, wherein the process includes a current and at least one previous erosion cycle, the current and the previous erosion cycle each being divided into predetermined time intervals each including at least one discharge pulse, wherein similar working gap conditions are present within a time interval of the previous erosion cycle and of the current erosion cycle, and wherein subsequent erosion cycles are separated by a process pause cycle.
    Type: Grant

  • Devices and methods for detecting a processing electrode of a machine tool
    Patent number: 6707304
    Abstract: Devices and methods are disclosed for the contactless detection of a bar-shaped or wire-shaped processing electrode of a machine tool such as a spark erosion machine. The detection is based on measuring an impedance change in the measuring area, which is caused by the processing electrode moving through the measuring area. The impedance change is measured by one or more measuring electrodes disposed in the measuring area.
