Die-sinking EDM
In electroerosive machining by die-sinking, the shape of a tool called electrode is reproduced in a metal workpiece. Injection moulds for plastic parts are very often machined by die-sinking EDM.
The shape of the electrode is that of the part to be cast later.
In the machining area each discharge produces a crater (removal of material) in the workpiece and a burn-off (electrode consumption of the tool) on the tool. There is never any mechanical contact between the electrode and the workpiece. Usually, the electrode is made of copper or graphite.
