Investigation on the Impact of Silicon Carbide and Process Parameters on Wire Cut-EDM of Al/SiCp MMC

In the present work, a model based on dimensional analysis (da) coupled with the taguchi method to analyze the impact of silicon carbide (sic) was presented. the wire cut electrical discharge machining (wedm) performance of aluminium silicon carbide (alsic) metal matrix composite (mmc) was critically examined. to formulate da-based models, a total of 18 experiments were conducted using taguchi’s l18 mixed plan of experimentation. the input data used in the da models include a pulse on time, pulse off time, wire feed rate, % sic, wire tension, flushing pressure, etc. according to these process parameters, da models for the surface roughness and the material removal rate were predicted. the formulated da models showed a strong correlation with the experimental data. the analysis of variance (anova) was applied to determine the impact of individual parameters on response parameters.
