2015/10/6Nowadays, graphite is one of the most popular electrode materials in electrical discharge machining (EDM) processes due to the high rate of removal material which reduces machining times. This reduction has a direct impact on the cost of manufacturing the parts. In this research, the influence of EDM parameters and graphite electrode in an INCONEL 600 alloy has been studied for both positive

The key to Better Electrode Making

Although each mold and electrode could be different, there is a great deal of repetition that can be avoided by saving common tasks and processes as templates for future use. For example, the process described above for extending the surfaces can be saved as a template—with different templates for different electrode contours.

What are the Advantages of Using Wire EDM Machining?

Wire electrical discharge machining (EDM) is a method commonly used to cut almost any kind of electrically conductive material with a great deal of precision. The first electrode in this process is the actual material being cut, while the second electrode is created by having a thin, electrically charged EDM wire positioned between the lower and upper mechanical guides used for the process.

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning amber (from which the word electricity is derived), and hodos, a way.
