Abstract EN
In this paper, Response Surface Method (RSM) is utilized to carry out an investigation of the impact of input parameters: electrode type (E.T.) [Gr, Cu and CuW], pulse duration of current (Ip), pulse duration on time (Ton), and pulse duration off time (Toff) on the surface finish in EDM operation.
To approximate and concentrate the suggested second- order regression model is generally accepted for Surface Roughness Ra, a Central Composite Design (CCD) is utilized for evaluating the model constant coefficients of the input parameters on Surface Roughness (Ra).
Examinations were performed on AISI D2 tool steel.
The important coefficients are gotten by achieving successfully an Analysis of Variance (ANOVA) at the 5 % confidence interval.
The outcomes discover that Surface Roughness (Ra) is much more impacted by E.T., Ton, Toff, Ip and little of their interactions action or influence.
To predict the average Surface Roughness (Ra), a mathematical regression model was developed.
Furthermore, for saving in time, the created model could be utilized for the choice of the high levels in the EDM procedure.
The model adequacy was extremely agreeable as the constant Coefficient of Determination (R2) is observed to be 99.72% and adjusted R2-measurement (R2adj) 99.60%.
