Several works have been done to
investigate the effect of parameters such as voltage,current, discharge duration on MRR in EDM of nonconductive
ceramics, but the effect of input power on MRR in EDM of nonconductive ceramics is not known. Precise removal of
material (i.e. MRR) is essential to know to fabricate intricate and micro product. This paper aims to investigate the effect of
input power on the continuous machining of nonconductive ceramics and investigate the spalling effect in EDM of ZrO2
ceramic.
