Abstract
The main objectives of this study is to estimate the impact of process parameters on the Surface Roughness (SR) and Recast Layer Thickness (RLT), also to find out the empirical equations which refer to the interactions between input parameters and process responses. D2-Tool Steel was selected as the material of the workpiece while copper was selected as electrode material. The impact of independent variables could be recognized by Taguchi Method, these independent parameters include powder concentration, discharge current, and pulse on time. The results show that the model adequacy is acceptable for developed models because of the values for 𝑅𝑅2 is (96.24)% and (94.36)% for SR and RLT respectively.
