| Ringkasan: | Electrical Discharge Machining (EDM) is non-traditional manufacturing process for
shaping hard metals and forming deep and complex-shaped holes by arc erosion in
all kinds of electro-conductive materials. Despite that, EDM also a process of
utilizing the removal phenomenon of electrical discharge in dielectric, therefore the
electrode plays an important role which affects the material removal rate and the tool
wear rate. The mains problems in EDM is the high rate of tool wear. The objective
of this project are to study the behavior of electrode wear, to analyze the effect of
process parameter on electrode wears and propose an optimum machining condition
of EDM. As a result, there are 9 experiments will be conducted with different peak
current (IP) and gap size. And mathematical modeling which is Design of
Experiment (DOE) program is used to analysis data for optimization result. The
obtain result according to this study is the optimum machining conditions that can
be implemented to reduce the rate of the tool wear and at the same time the
machining productivity and process reliability are increased. |
