EDM machining is strictly confined to the engineering sector, as this technology can essentially only be used
for the removal of metal material. Unlike the other types of machine tools..., EDM does not remove metal by means of the cutting tool's connection to the workpiece, but rather the removal takes
place through the use of the erosive capacity of electrical discharges. The machining operations that exploit this technology are very high precision machining operations and are particularly
suitable for the machining of small and medium sized workpieces with high manufacturing complexity. Normally the pieces made by electroerosion do not require further grinding or finishing as
the cutting and removal carried out with this type of machining is extremely precise and without imperfections. There are essentially two types of EDM, die-sinking EDM and wire EDM. The latter
uses a tensioned wire that is used as an electrode to remove the material from the workpiece. Die sinking EDM, on the other hand, makes the workpiece by giving a complementary form to the electrode.
In this case the work is divided into two phases, the first one is the creation of a negative electrode shape and the second the actual machining with the obtaining of the piece with the desired
shape using the negative electrode previously made.
