Özet
Wire electrodischarge machining (WEDM) is a vital non-traditional machining method when die/mould production is considered. The selection of optimum machining parameters affects the die/mould lifetime 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 noted that pulse on and pulse off times were influential parameters on surface roughness, low of these times produced smoother finishes. This result would positively affect the die lifetime by reducing surface roughness if WEDM parameters were selected appropriately.
