“…We can prepare porous electrode with the help of Borax to create diffusion bond between particles without creating reduction environment also borax will help in improving micro hardness of electrode if prepared with this technique this idea supported by Suarez et al [17]. Also the pour will help in taking debris out of cutting zone without lifting tool and pours will work as chip pocked stated by Flano et al [20].…”

In the past years many researchers have done various advancements in material removal rate, wear of electrode is improved and various researches had done on physical and electrical parameters of EDM machine. This new research contributes the similar objectives to enhance the material removal rate and to increase the life of electrode by reducing the wear rate of electrode. So this paper review the past research work done on porous electrodes to improve the life of electrode and to reduce the lift up time of electrode to flush debris and various work on porous electrodes to reduce lift up time.

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.

“…In this aspect, a simple cylindrical tool is modified to improve flushing and machining performance. Various types of tool geometry used by researcher are foil, 10 slotted, 11,12 stepped, 13 peripheral slots, 14 bunched, 15 tubular, 16 semi-cylindrical, 17 inclined micro-slots, 18 helical slots, 19 single and double-helical, 20 and 3D printed complex profile 21 to improve machining performance. However, all the study was focused on the experimentation to enhance material removal rate and reduce tool wear rate.…”

In micro-electrical discharge milling (μED-milling), the rotation and forward feed motion of the tool is the key element responsible for evacuation of the debris particles. The inability to eliminate debris from the interelectrode gap (IEG) causes secondary discharge, short-circuit, and hampers removal rate. This problem is predominant in electrical discharge machining (EDM) where the tool is stationary. Various methods have been devised in the literature to boost debris removal from the IEG. In this paper, the use of a slotted tool with different cross-sections is proposed. The dielectric flow-field, debris trajectory, and cooling rate are calculated using computational fluid dynamics (CFD). Effect of different parameters such as tool rotation, gap size, jet velocity, the shape of slots on the dielectric flow is determined. The slots on the tool create turbulence which enhances the debris removal from the IEG. It also provides the space to accumulate the debris particles, thereby increasing the removal rate. The variation in the dielectric flow-field greatly affects the debris flushing from the IEG. The trajectory of the debris particles depends on their initial position in the IEG and they cool rapidly, which is validated using simulation and mathematical approach.
