Unlike other traditional mechanical
cutting methods, EDM removes materials away by sparks, which leads to high temperature and
pressure.
It's a good method to machine high hardness materials, but the heat during EDM process also causes recast layers.
So the Ra roughness values are: origin material>300µm>200µm>100µm.
