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.
Claims10
An EDM method comprising the steps of:
- defining a logical waveform;
- creating time slice information defining the waveform, the time slice information including a plurality of time slices each having an amplitude and a width;
- and
- amplifying the time slice information to create power to be delivered to an EDM electrode.

An EDM system comprising:
- a logic processor including a memory for storing a logical waveform;
- a shape controller for receiving the logical waveform from the logic processor and for generating time slice information defining the logical waveform, the time slice information including a plurality of time slices each having an amplitude and a width;
- and
- a power section for receiving the time slice information from the shape controller, for amplifying the power of the time slice, and for delivering the amplified power to an EDM electrode.
