Optimizing the Cutting Time and Surface Finish for EDMWire Cut Process of AISI 1045 Steel

Rusdi Nur, Muas M, Syah Risal


This paper aims to optimize the machined
surface as well as to study the effect of current strength and
wire speed on wire cut machining on AISI 1045 steel against
the timing of roughness of straight gear surface. The surface
results analyzed are the surface roughness values obtained by
conducting surface roughness testing. Variations of current
used are 3 amperes, 5 amperes, and 7 amperes, while the wire
speed used is 8mm / min, 10 mm, min, and 12 mm / min. In the
process of wire cut machining is used a brass cutting material
with 0.25 mm wire diameter. The results showed that the
greater the current and wire speed used then the surface
roughness value will be lower, otherwise the smaller current
and wire speed used then the surface roughness value will be
higher. The results of data analysis using ANOVA analysis,
correlation, and regression method obtained optimal condition
to get low surface roughness value and fast cut time that is at 7
amperes current with wire speed 8 mm / min.
