“…However, as mentioned in the Introduction, the literature [16][17][18][19][20][21] reveals that the following parameters are the most widely used among researchers: current intensity supplied by the generator of the EDM machine (I), pulse time (t i ), duty cycle (η) and polarity. Accordingly, these four factors have been considered in this particular research work.…”

Abstract:In this present research work, a new modelling of energy density in EDM (Electrical Discharge Machining) is proposed. Energy density can be defined as the amount of energy needed to get a unit volume of material removed, and for its modelling, the whole EDM process has been taken into account. This new definition lets us quantify the energy density that is being absorbed by the workpiece and the electrode. Results are compared to those obtained by die sinking EDM in an Inconel ® 600 alloy using Cu-C electrodes. Currently, this material is of great interest for industrial applications in the nuclear, aeronautical and chemical sectors, due to their combinations of good mechanical properties, corrosion resistance and extreme hardness at very high temperatures. The experimental results confirm that the use of negative polarity leads to a higher material removal rate, higher electrode wear and higher surface roughness. Moreover, the optimal condition to obtain a maximum MRR (Material Removal Rate) of 30.49 mm 3 /min was: 8 A, 100 µs and 0.6, respectively, for the current intensity, pulse time and duty cycle.

“…Finally, decomposed carbon, coming from both the electrode (when a graphite electrode is utilized) and the dielectric fluid (when hydrocarbon oil is used), bonded on the surfaces, forming a “shield layer”, which, although it may act protectively for the tool electrode, may also be unbeneficial for the MRR [ 18 ]. The peculiar behavior of MRR and TWR during EDM machining has been reported in the literature [ 43 , 44 ], hence, it is important, scientifically interesting, and should be further investigated. In Figure 3 , the Main Effect Plot and the Interaction Plot of MRR are presented.…”

A Comprehensive Study on Processing Ti–6Al–4V ELI with High Power EDM

et al. 2021

Electrical Discharge Machining (EDM) consists of a non-conventional machining process, which is widely used in modern industry, and especially in machining hard-to-cut materials. By employing EDM, complex shapes and geometries can be produced, with high dimensional accuracy. Titanium alloys, due to their unique inherent properties, are extensively utilized in high end applications. Nevertheless, they suffer from poor machinability, and thus, EDM is commonly employed for their machining. The current study presents an experimental investigation regarding the process of Ti–6Al–4V ELI with high power EDM, using a graphite electrode. Control parameters were the pulse-on current (Ip) and time (Ton), while Machining performances were estimated in terms of Material Removal Rate (MRR), Tool Material Removal Rate (TMRR), and Tool Wear Ratio (TWR). The machined Surface Roughness was calculated according to the Ra and the Rt values, by following the ISO 25178-2 standards. Furthermore, the EDMed surfaces were observed under optical and SEM microscopy, while their cross sections were also studied in order the Average White Layer Thickness (AWLT) and the Heat Affected Zone (HAZ) to be measured. Finally, for the aforementioned indexes, Analysis Of Variance was performed, whilst for the MRR and TMRR, based on the Response Surface Method (RSM), semi-empirical correlations were presented. The scope of the current paper is, through a series of experiments and by employing statistical tools, to present how two main machining parameters, i.e., pulse-on current and time, affect major machining performance indexes and the surface roughness.

“…Average thickness of recast layer rises as pulse-on-time rises at a persistent pulse current. It additionally rises meaningfully with the rise of pulse current at greater voltage and pulse-on-time as well as lesser flushing pressure and pulse-off-time (Verma and Sajeevan, 2015). The material of tool electrode obviously affects the thickness of recast and tempered layers.…”
