What is EDM Machining?

Electrical discharge machining, EDM, is a manufacturing process where material is removed from a workpiece using a rapid sequence of electrical current discharges between electrodes submerged in a dielectric liquid. The process is used to manufacture parts that are impossible to machine. Since EDM does not use mechanical force to remove material, it is considered to be non-traditional.

EDM is an exceptionally precise process that is ideal for forming complex and intricate shapes and is capable of shaping hard metals such as titanium. The materials shaped using EDM must be electrically conductive for the process to be successful.

The workpiece electrode, anode, of an EDM machine is connected to the positive terminal of a DC power supply while the tool electrode, cathode, is connected to the negative terminal. The electrodes are submerged in the dielectric fluid and separated by the spark gap. Sparking generates extreme electrothermal heat in the spark gap zone, which melts and vaporizes parts of the workpiece surface, a process known as spark erosion.

The EDM wire machining process, an alternative to sinker EDM machining, works much like a wood band saw using a wire for the cutting process. The wire, made of copper or brass, has a high voltage electrical discharge passed through it that makes it possible for the wire to cut through the thickness of the workpiece.

The wire in EDM wire machining creates a spark in deionized water where conductivity is precision controlled. The water cools the material and washes away the removed material with clean dielectric fluid being constantly pumped into the process to flush the excess waste away.

The extreme temperatures of the EDM process rapidly removes excess material from the workpiece by vaporization and melting or spark erosion. The molten metal is partially removed. As the electric potential is withdrawn, the plasma channel is no longer sustained and generates pressure or shock waves as it collapses. This evacuates the molten material forming a crater of material that is removed from around the spark site.

Material is removed by the formation of shock waves as the plasma channel collapses due to electric potential discontinuation where the work material is made positive and the tool negative. As the electrons strike the workpiece, craters are formed by the heating, melting, and removal of material as positive ions strike the tool resulting in tool wear.

Electrical discharge machining requires a great deal of power. Generators used for the process must be capable of supplying the necessary power in order for the process to run efficiently and successfully. They are selected in accordance with their ability to generate the power parameters of the process.
