EDM, abbreviated as EDM, is a non-traditional method in which heat energy is used to remove data from the workpiece. Similar to the process of laser cutting, EDM does not require mechanical force in the removal process. This is why it is considered unconventional, as opposed to machining with cutting tools, for example.

EDM is very popular because it is suitable for hard materials such as titanium, or for milling complex shapes that are difficult to achieve.

When the voltage between the two electrodes increases, the electric field strength in the volume between the electrodes becomes stronger, leading to the dielectric breakdown of the liquid and the generation of an arc. The data was replaced by electrodes. Once the current is stopped (or stopped, depending on the type of generator), the new liquid dielectric will be transferred to the space between electrodes, so that the solid particles (chips) are taken away, and the dielectric insulation function can be maintained. Recovered. Adding new liquid dielectrics to the volume between electrodes is usually called flushing. When the current flows back, the voltage between the electrodes returns to the voltage before the breakdown, so as to generate a new liquid dielectric breakdown to repeat the cycle.
