In the present study, the wire cut electric discharge machining (WEDM) parameters were optimized for the machining of Silicon Carbide (SiC) and Titanium Dioxide (TiO2) reinforced LM25 aluminum alloy composite (SiC–TiO2–LM25 Al Alloy composite). The heat treatment was conducted in a muffle furnace and it was performed with solution treatment followed by water cooling and then artificially aged for 4, 6 and 8 h, followed by natural cooling at room temperature. The microstructural and hardness evaluation was conducted to investigate the effect of heat treatment on the Hybrid Metal Matrix Composite. The L9 orthogonal array table was utilized to perform the WEDM experiments. The effect of control variables such as ageing duration (4, 6 and 8 h), pulse on time (1, 2 and 3 µs) and wire feed rate (1, 2 and 3 mm/s) on the cutting speed (CS) was studied. The microstructural examination confirmed the presence of evenly distributed reinforcement particles with spheroidised SiC in the heat treated composite. The 6 h aged sample showed maximum hardness of 112.3 HV compared to various aged samples. The result showed that an ageing time of 8 h, pulse on time of 2 µs and wire feed rate of 2 mm/sec was identified as the optimum control variables to obtain maximum CS. Moreover, ANOVA analysis showed that ageing duration significantly affected the CS followed by wire feed rate and pulse on time. The confirmation experiment showed an increase in CS with optimum control variables.
