Micro Electrical Discharge Machining is currently widely used in the manufacturing in a variety
of applications, like in the production of micro parts for watches, keyhole surgery, housings for
micro surgery, and also tooling inserts for fabrication of micro filters. This study is undertaken
with the objective of analyzing various methods of Micro EDM setup and factors and parameters
which affect the end product quality and process and to also propose design parameters for
production of micro channels with bio-applications. . A brass tube electrode is selected with
multiple passes with a resetting of Z-coordinate used as wear compensation method. A R-C
generator with 75Vand 0.5A with a pulse on time of 12us is selected to give the best balance
between MRR and accuracy. Lastly, de-ionized water is used as a dielectric fluid because its
chemically inert and will not pollute the micro channel which is to be used in bio-applications as
well as provide a stable MRR.
