“…The modeling and optimizing technological parameters in PMEDM is preferred as one of the main research direction by many technical experts [32] . Many computational techniques such as Taguchi, ANN, GRA, Topsis, TGRA, etc were successfully applied to optimization in EDM [33][34][35][36][37] . These techniques have also been used to model and optimize single or multiple targets in PMEDM process.…”

It is very essential to form such high stregth and hard-to-cut materials by using modern machining methods. It is important to introduce the efforts on modification of the process for improving the machining quality. In the present investigation, an effort was made to analyze the effects of micro size aluminium particles mixed dielectric medium under different powder concentration on machining titanium alloy in electro erosion process. The response-surface-methodology(RSM) based algorithm was utilized to analyze the performance measures by considering machinning time with Cost of Goods Manufactured (COGM) method in PMEDM process. It was found that the micron size powders can significantly help to enhance the surface quality of the Ti-6Al-4V surface during machining in EDM process. The presence of carbon, oxygen elements and the formation of surface oxides and carbides has been found due to the decomposition of dielectric fluid in PMEDM process. The lower deep cavities and uniform machining surface have been produced with the aluminum oxide powder EDM process owing to lower surface cracks density, conductivity. To sum up, investigation and comparison of surface scanning showed that this setting has been implied could be considered by the industries needs more precision.

“…Multicriteria decision-making to develop surface performance measurement in the EDM process using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) has been utilized. Minimum levels of average white layer thickness and surface roughness at maximum compressive residual stress are obtained while machining AISI 304 stainless steel showed the most influent parameter which was current for plasma formation [9]. Taguchi-Grey analysis-based criteria decision-making was applied to evaluate quality characteristics (like recast layer thickness, wire wear ratio, and microhardness) of the wire EDM process.…”

The role of rapid tooling (RT) in additive manufacturing (AM) seems essential in improving and spreading out the vista of manufacturing proficiency. In this article, attempts were made to discover the feasibility and the accomplishments of the RT electrode in the field of electro-discharge machining (EDM). Fused deposition modeling (FDM) is one of the AM processes adopted to fabricate the EDM electrode prototype by coating with copper. The copper is deposited on FDM-built ABS plastic component for about 1 mm through thick electroplating. The copper-coated FDM (CCF) and solid copper (SC) electrodes are used to conduct experiments on a die-sinking EDM machine using tool alloy steel as a workpiece. The CCF polymer electrode can be efficiently used in EDM operations as the build time of any complex shape was substantially reduced. However, the material removal rate (MRR) is far less than that of the SC electrode. It is recommended that the CCF electrode is used for semifinishing and finishing operations in which MRR happens to be less. However, CCF can get spoiled as high temperatures are generated on the machining tool, and the plastic core hardly sustains such high temperatures.

“…Sivapirakasam et al, [26] used fuzzy-TOPSIS technique for the optimization of output responses such as process time, relative wear rate of the electrode, process energy and dielectric consumption in EDM process. In the Electrical Discharge Machining of AISI 304 steel, Huo et al, [27] used TOPSIS approach for the multi response optimization and obtained optimal setting for the surface roughness, white layer thickness and compressive residual stress.…”

In this study, an attempt has been made in PMEDM process to sustain the homogeneity in the powder-dielectric mixture irrespective of the nature of the powders, their particle size, concentration etc., The traditional way of powder mixing system in Powder Mixing Electric Discharge Machining (PMEDM) has been refurbished with a novel Eductor based system along with a metering devise to ensure uniform mixing of the powers with the dielectric. Additionally sintered crucible filtration test on the sample of powder-dielectric mixture ensured the presence of known quantity of powders in the dielectric. The experiments are conducted on Titanium alloy with Gap current, Duty factor, Delivery pressure, powder types (Alumina, Silica, and copper) and concentration of these powders as variable process parameters. The output responses, namely material removal rate, tool wear index and surface finish obtained during the machining process have been optimized using AHP-TOPSIS method. The confirmation test indicated that the closeness co-efficient value for the TOPSIS analysis improved by 2.37% compared with the predicted value.
