“…The literature reveals that the mechanism of material removal in the EDM process is not yet very well understood. Undoubtedly, phenomena involved in the EDM process need to be investigated further in order to improve the process [36]. Because of that and based on [35], this present study makes an attempt to further investigate the EDM process and proposes a new energy density parameter (ρ E ) that takes into account the whole process.…”

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.

The machining of a glass material is highly complicated due to its physical as well as chemical properties. The electrochemical discharge machining is an integrated hybrid machining process which has utilized to machining of conducting materials as well as high strength non-conducting materials having brittleness and high hardness. In this research article, the electrochemical discharge machining experimental setup was built and fabricated for machining of non-conducting materials. The electrochemical discharge machining process was applied for drilling on soda-lime glass material. The experiments were done with reference to Taguchi L 27 orthogonal array approach and scrutinized by utilizing the MINITAB 17 software. The machined depth and hole diameter results were inspected after electrochemical discharge drilling on soda-lime glass material with considering the machining conditions such as voltage, electrolyte concentration, and rotation. The observation results showed that voltage is the major parameter for machined depth and hole diameter followed by electrolyte concentration and rotation of tool electrode.

The Electrochemical discharge machining (ECDM) is a hybrid non-traditional process which is specifically used for machining of conducting as well as non-conducting materials. In this research work, the fabricated ECDM experimental setup was used to machine the Soda-lime glass material with Brass tool material. The experiments were done on Soda-lime glass material with the help of Taguchi L27 orthogonal array method and analysed by using MINITAB 17 software. The average hole diameter and average machined depth results were checked after ECDM drilling on Soda-lime glass material with considering the input process parameters such as an electrolyte concentration, voltage and rotation. The experimental results indicated that voltage was the most dominant factor for average machined depth followed by an electrolyte concentration and rotation speed. The rotation speed was the most dominant factor for average hole diameter followed by voltage and electrolyte concentration.
