In Wire-EDM the machining time is relatively high compared to conventional cutting technologies. In addition the workpiece surface often needs to be polished in order to achieve a better surface roughness and to reduce the rim zone. In order to reach optimum results in Sinking-EDM one approach is the use of powder additivated dielectrics. Here the application of powder suspended dielectrics in Wire-EDM is investigated. Hence, the influences of different powder concentrations and machining parameters are analysed regarding average gap width, material removal rate and surface roughness in different workpiece materials.
