  • Electrical discharge machine time slice power supply
    Patent number: 11084112
    Abstract: The specification discloses an electrical discharge machining (EDM) system and method capable of defining an unlimited number of waveforms. The system and method define logical waveforms using a plurality of time slices, each having a voltage and a width. The time slices are applied to the system power section where they are amplified and delivered to the electrode.

  • Electrical discharge machining integrated control system
    Patent number: 9346113
    Abstract: An electrical discharge machining (EDM) system and method including (a) an electrode supported by a spindle, (b) a spindle support, (c) a workpiece holder, (d) a gap voltage measurement device, and (d) a single integrated controller. The single integrated controller is responsive to the measured gap voltage to control all of the spindle, the spindle support, and the workpiece holder, providing improved speed, accuracy, and part quality.
