Key Engineering of Electrical Discharge Machining: A Review
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 7
Abstract
EDM is one of the most extensively used non-conventional material removal processes. Both electrode (tool) and work piece must be electrically conductive. The spark occurs in a gap filled with dielectric solution between the tool and work piece. The process removes metal via electrical and thermal energy, having no mechanical contact with the work piece. Its unique feature of using thermal energy is to machine electrically conductive parts regardless of their hardness; its distinctive advantage is in the manufacture of mould, die, automotive, aerospace and other applications. In addition, EDM does not make direct contact between the electrode and the work piece, eliminating mechanical stresses, chatter and vibration problems during machining. In recent years, EDM researchers have explored a number of ways to improve EDM Process parameters such as Electrical parameters, Non-Electrical Parameters, tool Electrode based parameters & Powder based parameters. This new research shares the same objectives of achieving more efficient metal removal rate reduction in tool wear and improved surface quality. This paper reviews the research work carried out from the inception to the development of die-sinking EDM, Water in EDM, dry EDM, and Powder mixed electric Discharge Machining. Within the past decade briefly describing the Current Research technique Trend in EDM, future EDM research direction.
