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.
