ABSTRACT:
Disclosed are various embodiments of an EDM electrode dressing template comprising a body made of an electrically conductive material. Bonded to the body is a pad with an electrically conductive material with hardness greater than the body. An electrode with an eroded end is positioned proximate the pad and a DC current pulses between the eroded end and the pad. After a period of time, the eroded end is shaped into a dressed tip. Since the pad is less susceptible to spark erosion than the body, the electrode is more consistently dressed and the template is replaced less frequently.
