Compared to surface grinding, wire-electrodischarge machining (WEDM) is competitive because WEDM allows the machining of any type of conductive material, regardless of its hardness. Nevertheless, WEDM is not preferred for final machining due to the existence of the process-induced damaged layers. In this study, the damaged layers formed in hardened AISI 52100 steel by surface grinding and WEDM are researched and compared. It is found that the damaged layers for both grinding and WEDM are composed of the white layer and dark layer, and the white layer possesses a highly refined grain structure ...
