Electrical discharge machines (EDM) are widely employed in machining components containing complex profiles of hard-to-cut and machining materials. However, the fabrication-of-tool time for the EDM process is excessively high in the traditional machining method, which significantly affects the machining rate. Therefore, in this paper, a powder metallurgy (PM) technique is employed to fabricate the tool electrode using copper (Cu), titanium carbide (TiC), and zirconium silicate (ZrSiO4) for different combinations. An L18 orthogonal array (OA) is planned using the following input parameters: three types of tools (Cu, Cu90, Cu80), peak current (PC) [A], pulse on time (PT) [µs], and gap voltage (GV) [V]. The performance of EDM is evaluated through the material removal rate (MRR), tool wear rate (TWR), and surface roughness (SR). The process parameters are optimized using two different techniques: the technique for order of preference by similarity to the ideal solution (TOPSIS) and grey relational analysis (GRA). TOPSIS and GRA optimization techniques produce the same optimal parametric solution for less TWR, SR, and higher MRR with the combination of the Cu90 tool, E8 APC, 15 µs pulse PT, and 75 V GV. Based on the ANOVA table of TOPSIS, pulse on time plays a major role, contributing 46.8 % of the machining performance; peak current shows the most significant contribution of 39.3 % of the machining performance using GRA values. Furthermore, the scanning electron microscope (SEM) image analyses are carried out on the machined workpiece surface to understand the effect of tools on machining quality.

“…Due to its crystalline nature the copper material produces more burrs while machining through conventional technology due to the tool structure, rotational speed and cutting forces [1,2]. On the other hand, among various techniques in unconventional methods, EMM provides right solutions for the problems stated above due to its advantages characteristics such as non-contact machining, no tool wear, high precision and excellent surface finish etc., [3,4]. In the view of enhancing the machining rate, researchers worldwide followed various strategies in EMM.…”

Micro hole is the fundamental feature found in any device/components. Hence this paper aims to produces the micro holes using electrochemical micromachining (EMM). The existing machining techniques in EMM for creating micro holes are associated with more overcut (OC). Hence, it is very essential to reduce OC and enhance the machining rate (MR). This paper aspires to investigate the effect of graphite electrode with magnetic force on copper plate. Four different tools namely electromagnetic graphite tool (EMGT), permanent magnet graphite tool (PMGT), graphite tool and stainless steel (SS) tool are employed for these experiments. The major influencing factors are machining voltage in volts, duty cycle in % and electrolyte concentration in g/l was considered on MR and OC. The results exposed that EMGT, PMGT and graphite electrodes produce MR of 106.4%, 74.6 % and 44.5 % over SS tool at parameter level of 23 g/l, 15 V, and 85% respectively. Graphite and EMGT electrode resulting in 11.9% and 3.41 % reduced OC respectively than SS tool at parameter level of 8V, 95% and 28 g/l. Additionally, scanning electron microscope (SEM) picture examination is conducted to identify the magnetic field effect on the work surface.

“…An application of micro features such as micro square holes, micro grooves, taper surfaces, slots, micro holes and micro slits were increasing enormously in micro electromechanical systems (MEMS). Also due to the miniaturizations of electronic, medical, biomedical and automobile devices the micro machining plays significant role in manufacturing [1][2][3][4].The documented knowledge in EMM for generation micro features is archived for micro holes .In line with that, Pradeep et al [5] studied the performance of EMM using cryogenic treated graphite electrodes on SS 304. The use cryogenic treated tool shows good stray current protection and improves the accuracy of the micro-hole.…”

The use of micro components is increasing day by day in the industries such as aviation, power circuit boards, inkjet nozzle and biomedical. Among various non-traditional micromachining methods, electrochemical micromachining (EMM) shows unique characteristics such as no tool wear, no residual stress and high accuracy. In this research EMM is considered to study the effect of square shaped stainless steel (SS) and aluminum metal matrix composite (AMC) tool on square hole generation. The significant process parameters such as machining voltage, duty cycle and aqueous sodium nitrate (NaNO3) electrolyte of varying concentration is considered for the study. The performances of EMM process are evaluated in terms of machining rate (MR) and Overcut (OC). The AMC tool shows 43.22 % lesser OC than the SS tool at the parameter combinations of 8V, 85% and 23 g/l. Also, for the same parameter combination MR for SS tool is 71.6 % higher than the AMC tool. Field emission scanning electron microscope image (FESEM) analysis shows that the micro square hole generated using composite electrode shows micro-pits on the circumference of the square hole. The energy dispersive X-ray spectroscopy (EDAX) analysis is conducted to verify presence and distributions of reinforcement in AMC tool.
