Description
Summary:This investigation presents the consequence of Wire EDM process variables over the kerf width (KW) of Al6063/SiC/Al2O3 hybrid composite which is fabricated by stir cast method. 31 experiments were conducted on the basis of response surface methodology central composite design. Kerf width is picked as the quality objective. The important coefficients are gotten by achieving successfully an Analysis of Variance (ANOVA) at the 5 % assurance interval. The outcomes discover that KW is much more impacted by Pulse on time, Pulse off time, current and control speed and little of their interactions action or influence. To predict the average kerf width, a mathematical regression model was developed. The forecasted value of optimum kerf width is 0.265 mm for Pulse on time (100), Pulse off time (48), current (200) along with control speed (60%).The Pulse on time is most influential variable for the kerf width. The results have been analyzed using Minitab version 18 software.
