Quality Analysis on Electrical Discharge Machined Metals

Electrical discharge machining, or EDM, is a manufacturing process that removes material via electrical
discharges [1]. This machining process is generally used with conductive metals that would be difficult
to machine with conventional methods.

As with all machining processes, precision and accuracy must be high in order to meet acceptable
tolerance levels. In this application note, the quality of the machined metals will be assessed with a
Nanovea 3D non-contact profilometer.
