Wire electrodischarge machining (WEDM) is a vital nontraditional

machining method when die/mould production is considered. The selection of

optimum machining parameters affects the die/mould life time which is one of

the major outputs in today’s manufacturing operation. In this experimental study,

a well-known tool steel (K390) has been machined by WEDM and the influences

of pulse on and pulse off on surface roughness have been examined. Three different

surface roughness parameters (Ra, Rq and Rz) were measured for determination

of their effects on surface quality. It was obtained that the die lifetime

could be increased by reducing surface roughness if WEDM parameters were

selected appropriately.
