Electrical discharge machining (EDM) is well established machining technique mainly used to machine complex geometries on difficult-to-machine materials and high strength temperature resistant alloys. In the present research, the objective is to study the shape of the electrode and establish the application of liquid nitrogen in reducing distortion of the electrode during electrical discharge m...

Abstract—Productivity and quality are two important aspects that have become great concerns in today’s competitive global market. Every production/manufacturing unit mainly focuses on these areas in relation to the process, as well as the product developed. The electrical discharge machining (EDM) process, even now it is an experience process, wherein the selected parameters are still often far...

Non-oriented electrical steel (NOES) laminations are commonly used to manufacture the rotor and stator core of electric machines. To achieve high machine efficiencies, it is desirable for these NOES be able a saturation magnetisation whilst incurring minimal losses. It known that inappropriate machining could cause significant deterioration in their magnetic properties. However, mechanisms by w...

In this paper, wire electric discharge machining (WEDM) of Titanium alloy (Ti-4.5Al-2V) is studied. In WEDM, the prime objective in cutting operation is to achieve the highest possible cutting speed along with desirable surface finish without sacrificing productivity. It is evident that a high material removal rate and a very good surface finish can never be achieved simultaneously in WEDM. Sel...

Ceramics are non-conductive materials, consequently, they cannot be machined directly by any electrical means. If these ceramics contain some small fractions of conductive components, e.g., as pollutant or glue perform a certain, really low level, local and accidental flash conductivity. The reported research was performed on this border science, with that below the practical also state-of-the-...

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...
