This study investigates the dry and near-dry electrical discharge machining (EDM) milling to achieve a high material removal rate (MRR) and fine surface finish for roughing and finishing operations, respectively. Dry EDM uses gas and near-dry EDM applies a liquid-gas mixture as the dielectric medium. Experimental studies leading to the selection of oxygen gas and copper electrode for high MRR d...

A low material removal rate and a high tool wear are two major concerns among the research development community of electric-discharge machining. From literature, it is evident that several researchers have attempted to improve minimize by different means, such as parametric optimizations, powder mixing in dielectric, induced vibrations electrode and/or workpiece, etc. Herein, an attempt made m...

Recent trend in reducing the size of products has given Micro Electrical Discharge Machining (MEDM) a significant amount of research attention. Due to the high precision, low tolerance and good surface quality that it can deliver, MEDM is potentially an important process for fabrication of micro-tools, micro-components and parts with micro-features. This paper briefs and highlights the various ...

In modern machining process, optimization technique is used to find the optimal values of input parameters and the effect of those parameters on response variables. If response parameters are more than one, Taguchi method of optimization may give different set of optimal levels for each response. In the present study, Taguchi-grey relational approach based multi response optimization has been u...

Technological advancement, on the one hand, makes Electrical Discharge Machining (EDM) much faster. One example of that is the presence of Wire Electrical Discharge Machining – High Speed (WEDM-HS) machine, which makes the material removal rate as high as 80 mm/min. On the other hand, it also make Abrasive Waterjet (AWJ) achieve much better quality surface and tighter tolerance. As a result, th...

Abstract Artificial intelligence (AI), robotics, cybersecurity, the Industrial Internet of Things, and blockchain are some technologies solutions that combined to produce “smart manufacturing,” which is used optimize manufacturing processes by creating and/or accepting data. In manufacturing, spark erosion technique such as wire electric discharge machining (WEDM) a process machines different h...
