Abstract :
The properties of the Inconel 718 super alloy
are used in the manufacturing of aircraft components,
due to high hardness and toughness machining of such
alloy by conventional machining process is difficult. To
overcome this, nonconventional techniques are used,
from which electrochemical machining (ECM) is good
alternative. Electrochemical Machining (ECM) is a
nonconventional manufacturing process widely
employed in various industries due to its precision in
shaping complex, detailed components. This study
focuses on exploring and optimizing the key machining
parameters in ECM to enhance machining efficiency and
surface finish quality of Inconel 718. The research
methodology involves a systematic experimental
investigation, employing a series of controlled tests on an
ECM machine. The controllable process parameters
selected which are current, voltage and duty cycle. The
aim is to comprehend the nuanced influence of these
variables on material removal rate (MRR) and overcut
and to investigate optimum level of process parameter.
The analysis shows that the duty cycle and current are
most influencing factor for controlling depth of overcut
and for improving MRR, but excessive high duty cycle
can be counterproductive which results in increased heat
generation because continuous current flow generates
heat in the electrolyte and work piece.
