Abstract :
Wire electrical discharge machining (WEDM)
is widely used in machining of conductive materials
when precision is considered as a prime importance.
This work proposes a three dimensional finite element
model (using ANSYS software) and new approach to
predict the temperature distribution at different pulse
time as well as stress distribution in wire. A transient
thermal analysis assuming a Gaussian distribution heat
source with temperature-dependent material properties
has been used to investigate the temperature distribution
and stress distribution. Thermal stress developed after
the end of the spark and residual stress developed after
subsequent cooling. The effect on significant machining
parameter pulse-on-time has been investigated and
found that the peak temperature sharply increases with
the parameter.
