| Abstract: | This study presents a finite element model (FEM)
to model temperature distribution for AISI H13 tool steel workpiece in
electrical discharge machining (EDM) at different machining parameters (pulse
current, pulse on-time, temperature-sensitive material properties, size of heat
source, and material flushing efficiency). Scanning electron microscopy (SEM)
with energy dispersive x-ray (EDX) and micro-hardness tests were used to
validate accuracy of FEM predictions. Increasing pulse on-time leads to a
higher depth of heat affected zone and increasing pulse current results in a
slight decrease of depth of heat affected zone. There is a good agreement
between experimental and numerical results. |
