hi all;
actually i have done an experiment using die sinking EDM using one copper electrode and three different work piece material copper aluminum and stainless steel to perform a comparative study in term of MRR, TWR and surface roughness. i used ( pulse current 8, 12, 16, 20 and 24 Am... the pulse off is 7 micro second), so that i expected to have the same result in published papers i have read but i came up with confusing result for example i got unstable tool wear rate and my question is there any justification for this issue. i have attached these figures to have a look and please not that ,2,3 and 4 representing the 13,25,50 and 100 micro second .
Thanks
Hamdi
