Electrical Discharge Machining (EDM) is a competitive technology for this operation, since it does not depend on material hardness and can fulfill strict geometrical requirements. 2. manufacturing: research, technology outcomes and. Compared with conventional machining—from basic CNC turning all the way up to 5-axis—EDM has certain advantages and disadvantages. are difficult to cut, EDM is still required [54]. 2 Sometimes it is referred to as spark machining, spark eroding, burning, die sinking or wire erosion Its a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). EDM machining process is also known as spark erosion machining. ELECTRO CHEMICAL MACHINING Introduction: The process of metal removal by electro chemical dissolution was known as long back as 1780 AD but it is only over the last couple of decades that this method has been used to advantage. Being a developing country, the electric power required in Bangladesh has been expanding at an essentially high rate. In the present book chapter, Copper-SiC-Graphite hybrid metal matrix composites were prepared by liquid state stir casting process. The choice of reinforcement material is highly influenced by their mechanical properties such as hardness, wear resistance, cost advantage, availability in market and refractory nature. An extensive literature survey is taken for this study from the various databases like Elsevier, Springer and Web of Science. Micro-, Liu, K., Reynaerts, D., & Lauwers, B. Optimal machining parameters for machining SS304 materials identified namely; Current 10, Pulse on Time 60 μs, Pulse off Time 35 μs. Many studies have been done on the factors, drivers and barriers in renewable energy in Bangladesh. In the last few years, the demand of energy over the globe is increasing at the rapid rate due to the rapid growth in industrialization in developing countries. Understanding Electrical Discharge Machining 25 C. Small Hole EDM Drilling Small hole EDM drilling, also known as fast hole EDM drilling, hole popper, and start hole EDM drilling, uses a guided hollow electrode to drill holes by means of electrical discharge machining by eroding material from the workpiece, as shown in Figure 1:4.
