Experimental Investigation to Determine Influence of Process Parameters on Surface Quality and MRR in Wire Cut EDM
The objective of the present work is to investigate the effects of the various Wirecut EDM process parameters on
the surface quality, maximum material removal rates and obtain the optimal sets of process parameters so that the quality and
MRR of machined parts can be optimized. Experiments will be conducted on the pieces by parameters. The material used for
machining is Aluminum alloy and the process parameters varied are Pulse Time on 110μsec, 109μsec, 108 μsec, Pulse Time
off 60μsec, 61μsec, 61μsec and Peak Current180Amps, 170Amps, 160Amps. Wire Feed, ServoVoltage and Wire Tension
are kept constant. The optimization is done by using Taguchi technique by considering L9 orthogonal array. Optimization is
done using Minitab software.
