A Review of Unconventional Procedures for Manufacturing Tool Electrodes Used in EDM
Journal Title: RECENT - Year 2014, Vol 15, Issue 43
Abstract
Electrical discharge machining (EDM) is an unconventional process for machining electrically conductive materials that are difficult to process by other known means. EDM requires that the tool, at least in the die sinking technology, to be the negative of the cavity to be processed. Therefore, processing of tool electrodes is a necessary step but also is the cause for substantial costs associated with machining and the time needed to complete it. Technologies based on the principle of additive manufacturing could be a viable alternative to produce these electrodes. This paper intends to provide a review of possibilities of additive manufacturing - AM to be used as a process to produce tool electrodes to be used in die-sinking EDM.
