Abstract

Wire Electrical Discharge Machining (Wire-EDM) using electrical energy to cutting materials, they penetrate material not continuously instead penetrate with a specific interval that called as a pulse on time. Open voltage is a variable to control value of penetrate energy. Material removal rate caused melted and evaporation work piece material. Flushing by dielectric fluid affected quenching on the surface machined materials. During Wire-EDM process, re-heating of melted material. Constant quenching and re-heating also caused the craters to be relatively deep and width on a microscale. That’s craters affected has impact on surface roughness on macro scale. In Wire-EDM process, surface roughness is important to describe deviation characteristic on surface of workpiece. A research conducting to observe micro topography by using variable pulse on time and open voltage, including surface roughness on tool steel surface who has processed using Wire-EDM. This research using design experiment factorial 3x3. Surface roughness measurement conducting using Mitutoyo surftest. Surface electron measurement (SEM) used to observe micro topography on workpiece surface. From this research we can conclude that pulse on-time and open voltage directly proportional to surface roughness response variable. From this research was achieve lowest surface roughness 1,33 μm on combination pulse on time 2 µs and open voltage 75V and the highest surface roughness 2,52 μm on combination pulse on time 6 µs and open voltage 105V.
