“…The NiTi alloy is in martensitic phase at low temperatures and in the austenitic phase at high temperatures [4]. A review of the literature showed that different manufacturing processes are used for the machining of NiTi alloy such as laser processing method [5][6][7][8][9][10][11][12][13][14][15][16], electrical discharge machining (EDM) [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], electrochemical polishing [32] and abrasive water jet processing method (AWJM) [33,34] for shaping NiTi alloy and also conventional machining methods (Turning [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50], milling…”

Shape memory alloys (SMAs) are increasingly used in the fields of aviation, automotive and biomedicine due to their unique properties. Nickel-Titanium (NiTi) alloy materials, which are one of the shape memory alloys, are among the most frequently used alloy materials. The shape memory and super elastic effects of NiTi alloys, high ductility and deformation hardening make it difficult to shape burr. An additional problem is the formation of a white layer during machining. In this study, surface milling operations were performed in dry cutting conditions with uncoated cutting tools with different nose radii. The processing parameters were determined based on the experience gained as a result of the preliminary tests. Tungsten carbide cutting tools with different nose radii (0.4mm and 0.8mm) were used for the milling operations. Milling was carried out at three different cutting speeds (20, 35, 50 m/min), feed rates (0.03, 0.07, 0.14 mm/tooth), and a constant axial cutting depth (0.7 mm). As a result of our experimental studies, the best tool life was found to be in 0.8 mm nose radius cutting tools at 20 m/min cutting speed and 0.03 mm/tooth feed rate (0.264 mm). The minimum average surface roughness was found after milling with 0.8 mm nose radius cutting tool at 20 m/min cutting speed and 0.03 mm/tooth feed rate (0.346 μm). It has been determined that increasing the cutting tool nose radius reduces both the flank wear over the cutting tool and the average surface roughness.

“…In case of ultrasonic-assisted EDM (UAEDM), combining of EDM with ultrasonic vibrations is found to be one of the most effective shared hybrid machining processes with increased metal removal rate during machining of electrically conductive very hard materials [157]. Hybrid machining process which combines laser and micro-EDM processes for drilling microholes in complex engineering materials such as nickel-titanium (Ni-Ti)-based shape memory alloy (SMA) is an example of recent use of hybrid machining process technique [158].…”

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.

Un-conventional or non-traditional machining methods generally create a phantasm in mind that these are very new. In reality these methods are named so because of the process mechanism in which no shear force is used directly neither there is any contact between tool and workpiece. This does not insinuate that these processes are new because 1694 saw the dawn of EDM when Sir Robert Boyle described the phenomena of electric discharges, 1952 saw the birth of electron beam technology andin the year of 1957 and Gordon Gould designed the first laser device. All these non-traditional processes have developed rapidly in last few decades and are now the state of the art of the present manufacturing technology. Among these EDM has accrued a lot because of its advantages over other non-traditional processes. This accruement is result of various unprecedented ideas those changed the countenance of EDM and made it more efficient and economic process among the non-traditional processes. This paper presents the literature survey to throw light on all those ideas those lead to the current state of the art of EDM.
