Experimental Investigation Of Machining Parameters In Wirecut EDM

This work includes 1.Examining the effect of machining current on the out put parameters, i.e. cutting speed, spark gap, MRR and surface finish. 2.Determining the best suitable or optimum machining current value to be used for machining different thickness work pieces for the four materials under present study. 3.Study the effect of work piece thickness on process parameters, i.e. machining current, cutting speed, spark gap, surface finish and MRR and to arrive at optimum values for all four non-ferrous materials under present experimentation. 4.Develop mathematical correlations for determining the machining current to be set on WEDM for machining any thickness of the work piece among the materials tested and also for calculating the cutting speed, spark gap and MRR. 5.Analyze the effects of various thermo-physical properties of work piece material on the machining criteria, i.e. machining current, cutting speed, spark gap, surface finish and MRR.
