Abstract: The of ratio low weight to strength desires to special applications of automobile and components of aerospace which found new scope for advanced studies on “Metal Matrix Composites (MMCs)”. In the present research optimization of WEDM process parameters viz,. “Voltage (V), discharge current (I_p), pulse on Time (T_on) and pulse off Time (T_off) “are carried out to minimize “the White Layer Thickness (WLT)” and “Surface Crack Density (SCD)” of Al-2024 reinforced with volume fraction of 10% TiC_p and 10% B₄C_p separately by Taguchi method and design of experiments. The array of standard L₁₈ orthogonal has elected for experiments design. The results have gotten from the experimental runs have analyzed via. using “Minitab 16 Software”. The process parameters which effecting on WLT and SCD have found by ANOVA for S/N ratios. In this experimental study, it has noticed that WLT and SCD have mainly affected by all process parameters except T_off has little effect on the SCD. The identical values of the response parameters have calculated by mathematical formulae and promoted by carry out validation experimentation. The values of confirmation tests, all being found to be quite satisfactory (2.660% in the worst case), prove the efficacy and reliability of the suggested approach.
