| Summary: | ABSTRACT This article presents a novel approach for fabricating micro‐channels in carbon fiber‐reinforced compositA.J.Se (CFRC) using micro‐electrical discharge machining (μEDM) assisted by particle‐mixed dielectric. The impact of the prime machining parameters such as voltage (V), particle concentration (PC), and tool speed (TS), on machining time (MT) was assessed through the experimentation as per Taguchi's L16 orthogonal array. The machining parameters were significant, as indicated by the ANOVA, with p‐values below 0.05 for a 95% confidence interval. The regression study indicates that voltage has the greatest impact on MT variation. The optimal values of V, PC, and TS for the minimum MT were 180 V, 2 g/L, and 600 rpm, respectively. The highest discrepancy in the MT between the experimental value and the fitted value according to the regression relation was determined to be merely 3.2258%, indicating the adequacy of the generated regression model. The examination of the surface characteristics of the micro‐channels demonstrated that non‐uniform machining leads to the development of a rough and irregular surface on the material. The overcut from excessive material removal at the micro‐channel's periphery leads to deviations in the intended dimensions of the micro‐feature. |
