The machinability study on Wire Electro Discharge Machining (WEDM) of Al6061/20%SiC has been investigated in the present exploration. The objective of this present investigation is to determine the best possible process parameter to obtain better machining performance during wire EDM of Al6061 matrix reinforced with 20 wt. % SiC which is fabricated through the stir casting processes. The machining parameters such as pulse on time, pulse off time (delay time) and servo voltage are deemed as input process variables. Rate of material removal and roughness of the machined surface were considered as performance measures under this investigation. Taguchi’s design of experiment approach has been adopted for designing the experimental runs and L9 orthogonal array has been selected for conducting the experiments. Analysis of Variance (ANOVA) is adopted for ascertaining the significance of process parameters. Taguchi’s response analysis has been employed to determine the ascendancy of process parameters and the optimum process parameters were determined to obtain better machining performance.

Abstract


The machinability study on Wire Electro Discharge Machining (WEDM) of Al6061/20%SiC has been investigated in the present exploration. The objective of this present investigation is to determine the best possible process parameter to obtain better machining performance during wire EDM of Al6061 matrix reinforced with 20 wt. % SiC which is fabricated through the stir casting processes. The machining parameters such as pulse on time, pulse off time (delay time) and servo voltage are deemed as input process variables. Rate of material removal and roughness of the machined surface were considered as performance measures under this investigation. Taguchi’s design of experiment approach has been adopted for designing the experimental runs and L9 orthogonal array has been selected for conducting the experiments. Analysis of Variance (ANOVA) is adopted for ascertaining the significance of process parameters. Taguchi’s response analysis has been employed to determine the ascendancy of process parameters and the optimum process parameters were determined to obtain better machining performance.
