This paper proposed a hybrid intelligent process model, based on finite-element method (FEM) and Gaussian process regression (GPR), for electrical discharge machining (EDM) process. A model of single-spark EDM process has been constructed based on FEM method, considering the latent heat, variable heat distribution coefficient of cathode (f c ), and plasma flushing efficiency (PFE), to predict material removal rate (MRR) and surface roughness (Ra). This model was validated using reported analytical and experimental results. Then, a GPR model was proposed to establish relationship between input process parameters (pulse current, pulse duration, and discharge voltage) and the process responses (MRR and Ra) for EDM process. The GPR model was trained, tested, and tuned using the

“…With the increase in pulse duration MRR showed a peak and then downfall (Chen and Mahdivian, 2000;Lin et al, 2006;). Increase in discharge energy by discharge voltage or capacitance, resulted in higher MRR (Kim et al, 2005).…”

“…Accompanying the cooling process after the spilling of molten metal, residues remain at the periphery of the crater to form a rough surface (Liao et al, 2004). Theoretical model for R y or R max was developed for transistorized pulse generator type EDM (Chen and Mahdivian, 2000). It showed that with the increase in current and pulse duration, R y increased.…”

Abstract-Electro discharge machining (EDM) is anunconventional electro thermal machining process used for manufacturing geometrically complex or hard material parts that are extremely difficult-tomachine by conventional machining process. Modelling of the EDM process provides a functional relationship between operating parameters and output parameters (process performance index) of EDM process. This is the scientific way to study quantitatively EDM process behaviour which helps to get the better understanding of the process. This paper reviews various research work carried out within past decades for the development of EDM process. The study is mainly focused on aspects related to the experimental modelling of EDM process using Artificial Neural Network (ANN) and Response Surface Methodology (RSM).
