Electrical Discharge Machine (EDM) is especially used for the manufacturing of 3-D complex geometry and hard material parts that are extremely difficult-to-machine by conventional machining processes. In this paper authors review the research work carried out in the development of die-sinking EDM within the past decades for the improvement of machining characteristics such as Material Removal R...

Titanium surfaces processed by wire-type electric discharge machining (EDM) are microfabricated surfaces with an irregular morphology, and they exhibited excellent in vitro bone biocompatibility. In this study, the efficiency of in vivo osteogenesis on EDM surfaces was investigated by surgically placing screw-shaped EDM-processed and machined-surface implants into the femurs of four Japanese wh...

Advances in micromachining techniques have led to the evolution of micro-electromechanical systems (MEMS). These techniques are typically based on semiconductor manufacturing processes, which offer various advantages such as batch manufacturing of miniaturized devices and monolithic integration of microelectronics with the devices. Surface micromachining has been used to construct complex micro...

Advanced ceramic materials are gradually becoming very important for their superior properties such as high hardness, wear resistance, chemical resistance, and high strength to weight ratio. But machining of advanced ceramic like Al2O3-ceramics is very difficult by any well known and common machining processes. Normally, cleavages and triangular fractures generate when machining of these materi...

Micro Electric Discharge Machining is a nontraditional machining process which can be used for drilling micro holes in high strength to weight ratio materials. This present research study deals with the single optimization of micro EDM process using Genetic Algorithm. Mathematical models using Response Surface Methodology (RSM) is used to correlate the response and the parameters. The desired r...

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...

The operating control parameters of injection flushing type of electrical discharge machining process on stainless steel 304 workpiece with copper tools are being optimized according to its individual machining characteristic i.e. material removal rate (MRR). Lower MRR during EDM machining process may decrease its’ machining productivity. Hence, the quality characteristic for MRR is set to high...
