Abstract

Unlike conventional single special cut methods, W-EDM is a combination of multiple-effects. This study focuses on the effects of second cut on the roughness of surfaces treated with W-EDM. W-EDM is, to a large extent, typical unmanned-machining equipment, which represents NC machining equipment that allows long-time full automation. W-EMD is getting popular as a precise machining technology and STD11 is frequently used in press die manufacture. In this study, the former is applied to the latter to look at the effects of second cut on the roughness of surfaces treated with W-EDM.
