“…This is in line with existing studies. 22 The eroded particles in gap are removed more effectively with high t off values, and thus there is no continuous discharge, deep melting and structural deterioration on the surfaces are reduced. As a result, surface roughness decreases in the machining performed by keeping the 99 ms t off value constant.…”

“…7 Electric discharge machining (EDM) is a non-traditional erosion and material removal process with no physical contact between the tool and the workpiece. 8 Hard materials in ISO S and H classes are easily processed with EDM according to their electrical conductivity. Since there is no physical contact between the workpiece and the electrode in EDM, when voltage is applied between the electrode and the workpiece, metal-based materials can be easily shaped with the formed electric arc by ionizing the dielectric due to the high potential difference.…”

In this study, the machinability of B4C and TiB2 reinforced Al 2024 based composites produced by powder metallurgy was investigated with EDM (Electro Discharge Machining) method using two different copper electrodes. For this purpose, composite samples were produced at 6% TiB2+12% B4C reinforcement ratios. Then, scanning electron microscopy images were taken to examine the microstructure of the composite samples. Also EDAX analyzes were performed during SEM images. In EDM machinability experiments of the composite material two different electrodes; pure copper and beryllium copper were used. The experiments were carried out using three different current (I) and arc pulse on time ( ton) and two different arc pulse off time ( toff) parameters. As a result of EDM experiments, roughness measurements of the machined surfaces were made and SEM images of the machined surfaces were taken again. According to the experimental findings, material removal rate increased in machining with CuBe tool compared to machining made with pure Cu and CuBe tools showed higher wear tendency than Cu tool sunder the same machining conditions and roughness values in CuBe electrodes were lower than machining made with pure Cu. And the roughness values of CuBe are lower than the machinings with pure Cu.

“…Paswan et al [12] used steam as a dielectric during EDM of AMMCs and explored the effect of input parameters on the MRR, recast layer, and SR. Moghaddam et al [13] developed a model and optimize the EDM process by combining artificial neural networks and PSO. Mandal et al [14] applied MOPSO and TOPSIS for the multi-objective optimization of Cu-MWCNT composite electrode in EDM and observed that MOPSO can be effectively used for multi-objective optimization.…”

In this article, Response Surface Methodology (RSM) and Multi-objective Particle Swarm Optimization (MOPSO) were used to optimize the output response of Material Removal Rate (MRR) and Surface Roughness(SR) of die-sinking Electrical discharge machining (EDM). An aluminum based metal matrix composites, reinforced with alumina, prepared by stir casting, was used for machining on EDM by Copper (Cu) and Titanium (Ti) tool. Box- Behnken Design (BBD) approach of RSM was used to design the experiment by considering four input factors at three levels. This developed model for multi-objective optimization by MOPSO and an RSM-based multi-objective optimization was also designed for input parameters. And it was found that the MOPSO technique was easy and valuable for parametric optimization of EDM. From MOPSO, optimized input parameters for machining of AMMC using Cu tool are current 4A, Voltage 60V, pulse on-time 100 µs, and duty factor 6. From MOPSO, optimized input parameters for machining of AMMC using Ti tool are current 4.241658A, Voltage 60V, pulse on-time 100 µs, and duty factor 4. The confirmatory test found that MRR and SR decreased by 63.86 % and 53.083% for the Cu tool, respectively, for MOPSO compared to RSM optimize value.

“…In general, various parameters such as the pulse duration and the properties of dielectric uid affect the formation of the recast layer. Therefore, correct adjustment of machining operational parameters as well as the use of scienti c innovations play an important role in reducing the thickness of the recast layer, increasing the functional e ciency, and increasing the quality of the machined work pieces [5].…”

Inconel 625 superalloy and stainless steel 304 are known for their signi cant corrosion resistance along with their high hardness and strength. Therefore, they are used in a wide range of industries, including oil and gas, nuclear, etc. Electrical discharge machining is among the most widely used processes for machining of these metals. However, this process has limitations, such as low material removal e ciency, high surface roughness, and the formation of a recast layer. Therefore, in this study, the effective parameters on increasing the material removal e ciency and reducing recast layer thickness are investigated. These parameters include the dielectric uid, electrode material, discharge current, and pulse duration. After performing the test matrix, the effect of each of the input parameters on the material removal rate, surface roughness and thickness of the recast layer is evaluated using the ANOVA method. The results of this analysis showed that the type of dielectric uid and the presence of silver oxide nanoparticles have a signi cant effect on output variables. When using sun ower oil uid containing nanoparticles and the silver electrode, the recast layer and surface roughness are reduced, while the average material removal rate increases by 40% compared to the traditional mode. Also, due to the biodegradability of deionized water and sun ower oil uids, the environmental sustainability of the process in this study is increased and while increasing productivity, it leads to the sustainable development of the EDM process.
