Abstract

Strip EDM is similar to wire EDM, except that the electrode is a roll of brass strip. In this study, investigated is the effect of machining area on material removal rate (MRR) in strip EDM, The MRR was measured according to different machining areas and different electrical discharge conditions. For a given discharge condition, optimal machining area for maximum MRR was identified. The optimal machining area was larger under higher discharge energy condition. It is shown that strip EDM is much more efficient than wire EDM because material removal rate is much higher and the electrode consumption is much less.
