This studywork systematically investigated the effects of technological parameters on the technological responses, including the cutting velocity (CV) and surface roughness (SR) in the WEDM of SKD61 material. Technological parameters consist of current I, pulse on time Ton, pulse of time Toff, and wire speed S. A WEDM machine was adopted in conjunction with the Box-Behnken matrix to conduct experimental trails. |
