“…The electrochemical micromachining has various advantages and visible limitations are stray cut. Research on reducing the stray cut is reported by various researchers such as applying epoxy resin, electroplating of nickel and chromium, spin-coating, polytetrafluoroethylene and ceramic coated tools [1][2][3][4][5][6]. In this research the research the ceramic coated electrode is considered to machine copper plate in sodium nitrate electrolyte.…”

Electrochemical micromachining (ECMM) is an important machining process for machining materials susceptible to produce burrs during contact machining process. In this research copper plate of thickness 2mm and tool electrode of 464μm were machined through ECMM process under the sodium nitrate electrolyte (NaNO3).The tool electrode is coated with ceramic material and prevent stray current and chemical attack. The control factors namely, voltage, electrolyte concentration and duty cycle are varied on machining time and overcut. Higher voltage of 12V takes 1 minute to complete the through hole and the use of ceramic coated tool produces good arc on the circumference of the micro-hole and 65% reduction of overcut. The suitable range of electrolyte concentration for reduced machining time is 24 to 26g/lit. As per TOPSIS analysis, 10V, 24g/lit and 65% duty cycle and 11V, 24g/lit and 75% are the best optimal combinations. ANOVA results show that voltage and electrolyte concentration are the most significant factors with 57.73% and 28.83% contribution, respectively

Electrochemical machining (ECM) is a nontraditional technique for application of metal matrix composites in aerospace, military, and other engineering uses. ECM factors such as voltage, electrolyte concentration, duty cycle, and electrolyte temperature are varied to evaluate the machining rate. radial overcut, and delamination factor on scrapped alloy wheel MMC. The entropy-based weight assessment method coupled with gray relational analysis is used to perform multi objective optimization. As per the entropy method the weight assigned to MR, ROC and DF is 0.3105, 0.3432 and 0.3463, respectively. The gray relational grade predicts that 8 V, 20 g/lit, 50% and 40°C is the optimal setting for higher machining rate and lower radial overcut and delamination factor.
