ICALEO 2008 Paper #106 (Laser

Electrical discharge machining (EDM) is a simple (normally one-direction feeding) and efficient process for the fabrication of complex dies or moulds. However, the electrodes employed for EDM are usually difficult to be produced, being the major cost and time-consuming part of EDM, reaching more than 50 % of the total machining cost.
