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.

Description

technical field [0001] The present invention relates to an electrical discharge machining (electrical discharge machining, EDM) system and method, in particular to a control system and power supply for the EDM system and method. Background technique [0002] Electrical discharge machining (EDM), also known as spark machining, spark erosion, combustion, die-cutting, wire combustion or wire erosion, is a manufacturing process that uses electrical discharges to achieve a desired shape. Material is removed from the workpiece by a series of rapidly cycling electrical sparks between two electrodes. One of the electrodes is the tool, or simply an electrode, and the other of the electrodes is the workpiece. [0003] EDM systems and methods, as well as control systems and power supplies for such systems and methods, are well known to those skilled in the art. Figure 3 shows a typical prior art standard waveform 30 used in a system for powering an electrode spark. It can be seen th...
