“…At higher electrolyte concentration from level B2 to B3 (20% to 30%), the MRR slightly increases due to diminution of EDM action in machining mechanism. This finding is in agreement with micro-machining of copper plates, quartz glass and borosilicate glass using ECM and ECDM processes, respectively [ 29 , 30 , 31 ].…”

The applications of carbon fiber reinforced polymer composites (CFRPCs) in aerospace, automotive, electronics and lab-on-chip devices require precise machining processes. Over the past decade, there have been numerous attempts to machine CFRPCs using both traditional and unconventional machining techniques. However, because of their limitations, these methods have not gained widespread acceptance. In the present research investigation, Electrochemical Discharge Machining (ECDM) process has been employed to produce micro-holes on CFRPC. The experimental strategy was scheduled using L9 orthogonal array keeping applied voltage, electrolyte concentration and inter-electrode gap as input parameters. The material removal rate (MRR) and overcut were selected as output parameters. The technique for order preference by similarity to the ideal solution (TOPSIS) methodology was executed for multi-response optimization. The overcut and MRR of machined samples improved from 150 µm to 48 µm and 2.232 mg/min to 2.1267 mg/min correspondingly while using the optimum parametric settings of the TOPSIS approach. The shape of drilled micro-holes produced by the TOPSIS process is indicative of a machined surface of superior quality, with a reduction in the number of micro-cracks and a diameter that is uniform.

The production of miniature parts and various shape of micro-pro le by electrochemical discharge micromachining process (µ-ECDM) draw challenging attention to the researchers. Parametric in uences as well as comparative analysis on machining depth (MD) and surface roughness (R a ) has been propounded using NaOH and KOH at the ratio of 1:0, 3:1, 1:1, 1:3 and 0:1 with their varying concentration(wt.%), and applied voltage (V), pulse frequency(Hz) and duty ratio (%)in straight as well as in reverse polarity using template guided stainless steel (SS) cylindrical tool with motion and spring feed mechanism for fabrication of different shapes of micro-channel like Zig-Zag, 'Y' shaped on glass by µ-ECDM process.Tool electrode wear rate (TEWR) has been reduced using mixed electrolyte and reversed polarity. The SEM analysis has been performed to identify the micro-crack and uncut debris into micro-channel. Machining

“…Taguchi-GRA is extensively employed for evaluating the degree of relationship between arrangements by grey relational grade (GRG). Several researchers have recently used GRA technique to optimize the combination of different process parameters on sodalime glass [15], quartz glass [16], fiber glass reinforced [17], borosilicate glass [18][19], CFRP composites [12], silica (quartz) material [20], silicon wafer [21]. Works reported hitherto prove the effectiveness of Taguchi-GRA for optimizing ECDM process parameters; nevertheless the available literature reveals the scarcity of published works reported on micromachining of silica glass and relevant multi response optimization through GRA.…”

In this work, machining of microchannel in silica glass was successfully carried out using electro chemical discharge machining (ECDM) process. The experiments were planned according to L27 orthogonal array with applied voltage, stand-off distance (SOD), electrolyte concentration, pulse frequency and pulse-on-time (TON) as control factors. The material removal rate (MRR), overcut (OC) and tool wear rate (TWR) were considered as response characteristics. In this study the effects of control parameters on MRR, OC and TWR have been investigated. The multi-objective optimization of ECDM was carried out through grey relational analysis (GRA) method. Optimal combination of process parameters achieved from GRA was 45V applied voltage, 25wt.% electrolyte concentration, 1.5mm SOD, 400Hz pulse frequency and 45μs TON. ANOVA for GRG study revealed that the applied voltage (70.33%) was most significant factor affecting output responses followed by electrolyte concentration (11.69%), pulse frequency (4.98%) and SOD (4.13%). Furthermore, the regression equations were formulated for the optimum combination to predict the collaboration and higher-order effects of the control parameters. In addition confirmation test was conducted for the optimal setting of process parameters and the comparison of experimental results exhibited a good agreement with predicted values. The microstructural observation of machined surface for the optimum combination was carried out.
