A Review-Electrical Discharge Machining
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2019, Vol 16, Issue 1
Abstract
Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes. EDM process is based on thermoelectric energy between the work piece and an electrode. Amongst the various machining processes EDM is one of the most attractive alternatives for the industry due to its attractive attribute of not non-contact of tool and workpiece that leads to very little or no force exert in the tool and work piece. Electrical discharge machining is a process for shaping hard metals and forming deep complex shaped holes by spark erosion in all kinds of electro-conductive materials. In EDM, a process utilizing the removal phenomenon of electrical discharge in dielectric, the working fluid plays an important role affecting the material removal rate and the properties of the machined surface. Also, input parameters plays important role in determining the Material removal rate and surface quality. In this paper authors have reviewed the different types of electrical discharge machining, dielectric fluids used in the machining process and effect of peak current, voltage and pulse on time parameters on response parameters like material removal rate and tool wear rate. this research work carried out in the development of EDM within the past decades for the improvement of machining characteristics.
