“…The model simulated the influence of discharge duration and peak current on the average SR [116]. An inversion model showed that SR increases with the peak current level: the increase in current and pulse ontime in positive charged electrodes, EWR decreases, and the increase in pulse on-time increases the MRR [117]. The effect of pulse current had significantly linear relation with the EDM surface texture and square surface parameters [118].…”

Electro discharge machining (EDM) is a popular unconventional machining process widely employed in die-making industries. Careful selection of process parameters such as pulse current, voltage, on and off time, etc. is essential for machining of hard and conductive materials using EDM. Previous researchers working in the area of EDM have extensively analyzed the machining performance through experimental study, modeling, and simulation and also by theoretical analysis. This article discusses the significant summary of the work performed by earlier researchers through a detailed literature survey. Relevant literature on EDM and impact of process parameters on performance measures such as surface quality, tool wear rate and material removal rate are reviewed. The challenge and limitation of EDM process are also highlighted in this article. It is observed that optimization of process parameters is essentially required for effective and economical machining. So, this article addresses the various issues related to EDM and also provides brief insight into some of the current generation applications of EDM process explored in various industries.

“…Increased material removal rate and reduction in tool erosion observed because of this alteration. An inversion model based on least squares theory was proposed by Sanchez et al [2] for solving machining of AISI 1045 steel with a set of response parameters. Analysis of results showed that this model can be used in future applications in EDM machining.…”

Electrical discharge machining (EDM) is one of the oldest nontraditional machining processes, commonly used in automotive, aerospace and ship building industries for machining metals that have high hardness, strength and to make complicated shapes that cannot be produced by traditional machining techniques. The process is based on the thermoelectric energy between the work piece and an electrode. EDM is slow compared to conventional machining, low material removal rate, high surface roughness, high tool wear and formation of recast layer are the main disadvantages of the process. Tool wear rate, material removal rate and surface quality are important performance measures in electric discharge machining process. Numbers of ways are explored by researchers for improving and optimizing the output responses of EDM process. The paper summarizes the research on die-sinking EDM relating to the improvements in the output response.

“…The inversion model and forward model was constructed from a set of experiments for AISI 1045 steel. The conclusion was that, the inversion model was intended to be more flexible and simple since EDM parameters were easily worked out as a function of the admissible limits of the Ra, TWR and MRR which can be easily modified by the EDM user [6].…”

Abstract-Electrical discharge machining is a nontraditional machining process which removes metal by a series of discrete electrical discharges that cause high temperatures which is enough to melt or vaporize the metal. The process is adopted for the materials which often have special properties that make them difficult to machine by conventional machining. In present study work of different researchers has been discussed which shows the effect of process parameters such as pulse on time, pulse off time, gap voltage , peak current and duty factor on output responses such as tool wear rate (TWR), material removal rate (MRR) and surface roughness (Ra)
