“…Also when machining AISI 304 stainless steel with WC electrodes, Bhaumik and Maity [112] observed a major influence of discharge current and duration on MRR and TWR. Fu et al [105] compared WC and W electrodes during micro-EDM drilling of AISI 304, reporting that tungsten-carbide electrodes always achieved higher wear when compared to tungsten.…”

Over the years, sinking electrical discharge machining has become one of the most important production technologies to manufacture very accurate three-dimensional complex components on any electrically conductive material. This article reports a literature review on the diversity of conventional and non-conventional materials that are used or have potential to be used as EDM electrodes. In addition, additive manufacturing of EDM electrodes are also reviewed.

“…This approach is also used for fabricating blind noncircular microholes. Fu et al [48] used a 40 µm diameter of electrodes made of pure tungsten and a tungsten-carbide alloy to determine the effect of electrode materials on tool wear rate, and the side gap in the drilling of microholes by the µ-SEM process using machining oil (CASTY-LUBE EDS) and deionized water as the dielectric. They concluded that (i) TWR is more in machining oil as compared to deionized water; (ii) side gap-width increases with the increase in the drilling feed and drilling energy; (iii) tungsten electrodes produce more gap-width; (iv) TWR increases with machining feed; and (v) more TWR in tungsten-carbide electrodes than a bare tungsten electrode.…”

The increased demand for miniature components has drawn the attention of researchers, engineers, and industry users to manufacture precision micro and mesoholes on foils, sheets, and plates made from a variety of engineering materials. These days, micro-drilling is extensively being adopted as a fundamental operation in all kinds of smart manufacturing industries to make different types of microholes, such as through holes, blind holes, and taper holes on micro-parts and components. Drilled holes with a diameter of less than 1 mm are referred to as microholes, while drilled holes whose diameter ranges between 1 and 10 mm are known as mesoholes. Meso and microholes are commonly referred to as fine-holes. Modern or advanced drilling processes are mostly used to drill microholes from a variety of materials. This paper presents an extensive review of the previous research conducted on the drilling of fine holes (meso and micro size) by spark- erosion-based processes along with highlighting work and tool electrode materials, specifications of drilled holes, types of microholes (through or blind holes), process parameters, performance measures, and key findings. The paper aims to facilitate researchers and scholars by highlighting the capabilities of spark erosion machining, drilling, and its variants to fabricate miniature holes. The paper ends with a conclusion and future research directions to encourage further work in this area.

“…In another work by Shuliang et al (2017) high aspect ratio micro-holes are drilled using micro-EDM on C17200 beryllium copper alloy. Fu et al (2016) have focused their work on two major problems associated with micro-EDM; slow machining rate and high tool wear. The electrodes of pure tungsten and tungsten carbide were compared for tool wear with respect to two different dielectric fluids; oil and deionized water.…”

Simultaneous parametric optimization of micro-EDM drilling of brass C360 using Taguchi based grey relation analysis

Micro-EDM (Electro Discharge Machining) is widely used for precision manufacturing and drilling micro-holes in materials used in fuel nozzles, micro sensors and robots, surgical instruments, turbines etc. Present paper deals with drilling common C360 brass components by micro-machining and optimizing the process parameter using a hybrid approach of design of experiments (DoE) and grey relation analysis (GRA) concept. The three process responses considered are material removal rate (MRR), tool wear rate (TWR) and taper in drilled hole while the four selected controllable process parameters are capacitance(C), voltage(V), feed rate(f) and rotational speed of electrode (N). Significance of input factors on each response is analyzed with the help of a 24 full factorial by conducting 16 experiments at two levels for factors. Optimum levels of robustness for each process response are established through Taguchi’s S/N ratio. A combined grey relation grade is applied to find the process levels conducive for optimizing MRR and TWR simultaneously.
