Abstract:

An experimental study has conducted, in this work to determine statistical models for optimization of process parameters in wire EDM. Wire electrical discharge machining (WEDM) technology has extensively used in the field of medical, mould making, Die making , aerospace and automobile industries. WPS Die Steel(contains 1.5-1.8% carbon) is the hard material so that cutting by other machining is very difficult. But this cutting process make easy with wire EDM.WPS is widely used in making the press dies for cutting and forming operation therefore surface finishing of it is very important. The paper is focusing on to find out the combination of process parameters for optimum surface roughness and material removal rate (MRR) in wire electro discharge machining (EDM) of WPS Die Steel. The best combination of machining parameter viz. machine feed, pulse on time and pulse off time. The paper highlights the importance of process parameters and different machining conditions on MRR, surface roughness (Ra) and surface topography. In this work, machine feed, pulse on time and pulse off are input parameters and surface roughness and MRR as output parameters. The optimal values of these parameters have defined with the aim of achieving the better surface roughness and higher MRR.
