Modelling and Analysis of the Effect of EDM-Drilling Parameters on the Machining Performance of Inconel 718 Using the RSM and ANNs Methods

Abstract: Electrical Discharge Machining (EDM) is one of the most efficient processes to produce high-ratio micro holes in difficult-to-cut materials in the Inconel 718 superalloy. It is important to apply a statistical technique that guarantees a high fit between the predicted values and those measured during analysis of test results. It was especially important to check which method gives a better fit of the calculated result values in case they were relatively small and/or close to each other. This study developed mo… Show more

“…In view of contact between the mating surfaces, which are influenced by the degree of isotropy, wear may be intermittent or continuous [14]. Given a small degree of isotropy, the ridges of the irregularities move on one another, and given a high degree of isotropy, the ridges of microirregularities rest on one another or find their way into the cavities, ridge the opposite surface or become shorn [13]. In the latter case, there will be more wear products and the surfaces may demonstrate lower wear resistance.…”

“…According to Shahid Machno M et al [29], the thickness of the recast layer increased when the discharge current was intensi ed. The worn surface was present around the cavity's perimeter and was caused by an increase in spark energy [30][31][32][33].…”
