Fabrication of Ultrathin Sheet Using Wire-EDM
Generally, sheet products (coins, gears, washers etc.) are fabricated using blanking and punching operations. These are very time-consuming processes, and wastage is more. In this paper, coins of ultrathin sheets have been manufactured using wire electrical discharge machining (Wire-EDM). While machining, the effect of control parameters on the performance measures have also been studied. After experimentation, with the different combinations of the control variables, the sheet thickness has been found in the range of 47 μm to 154 μm. While machining, lower spark energy causes higher machining time, but the relatively better surface finish has been observed.
