Extremely hard materials can be easily machined by Electrical Discharge Machining process due to its thermal erosion nature. In this process, the amount of material removed is directly proportional to the discharge current. Due to the stochastic nature of the thermal erosion process, the discharge current is varied for every applied electrical pulse. It results in different levels of material r...

among the several non-conventional processes, electrical discharge machining (edm) is the most widely and successfully applied for the machining of conductive parts. in this technique, the tool has no mechanical contact with the work piece and also the hardness of work piece has no effect on the machining pace. hence, this technique could be employed to machine hard materials such as super allo...

Abstract Super abrasive diamond grinding wheels are the most promising tools for precision machining of advanced ceramics and carbide materials. However, efficiency conventional conditioning these is limited owing to high dressing tool wear, long process time, low form flexibility, induced damage grains. Wire electrical discharge (WEDM) an alternative method superabrasive with electrically cond...

With the properties of high specific strength, small thermal expansion and good abrasive resistance, particle-reinforced aluminum matrix composite is widely used in fields aerospace, automobile electronic communications, etc. However, cutting performance very poor due to severe tool wear low machining efficiency. Wire electrical discharge has been proven be a method for conductive material with...

Electrical Discharge Machining performance is generally evaluated on the basis of Material Removal Rate (MRR), Tool Wear Rate (TWR), Relative Wear Ratio (RWR) and Surface Roughness (SR). The important EDM machining parameters affecting to the performance measures of the process are discharge current, pulse on time, pulse off time, arc gap, and duty cycle [9]. A considerable amount of work has b...

In machining to improve machinability, productivity and to extend tool life coolants and lubricants where used .Increasing industry the use of cutting fluids subsequently increasing this leads in reduce of living conditions nearby future all the governments recommend the manufacturers to reduce the usage of toxicity cutting fluids. Still research for dry machining challenge is exiting for the i...
