In micro-EDM machining process, the debris of materials is difficult to be removed form the discharging gap.
Using this technique, the success of a micro-axis machining, tool steel and processed materials in a tiny hole milling, processing effect is good, indicating that the technique has a good application value.

These materials have very fine grain sizes (usually < 20), which remain stable at the temperature of deformation [1].
This frictional heat softens the material and extrudes it around the tool pin, mixing the two materials together.
