Abstract
Micro-EDM is a newly developed method to produce micro parts which in the range of 50-100μm.It is an efficient machining processes for the fabrication of a micro –metal hole with various advantages resulting from its characteristics of non-contact and thermal processes. In this paper the Taguchi design approach has been employed to investigate the micro –EDM parameters in order to achieve the highest Material Removal Rate (MRR), good surface quality and low Tool Wear Rate(TWR) while machining Ni-Ti based Shape Memory Alloy (SMA),it has been observed that MRR is highly influenced by capacitance , discharge voltage and depends up on the electrode material .Tungsten electrode is recommended for better surface roughness and brass electrode for better MRR
