In present research Micro channels have been fabricated using Wire Cut Electric Discharge Machining (WCEDM). In non-traditional machining processing, Wire Cut Electrical Discharge Machining (EDM) has tremendous potential on account of the versatility of its applications and it is expected that it will be successfully and commercially utilized in modern industries. Copper Micro channels are fabricated on Wire Cut EDM. These are heat transfer devices used for dissipation of heat from integrated circuits and other electronic devices. The performance of the micro-channels depends upon the machining parameters. In the proposed work, three input parameters of WCEDM are varied to get optimum responses. The parameters of WCEDM varied are peak current (Ip), Pulse on time (Ton) and pulse off time (Toff).The parameters of WEDM are varied in the ranges of (Ip from 100 to 200 ampere, Ton from 105 to 115 µsec and Toff from 25 to 45 µsec). Two responses material removal rate (MRR) and surface roughness (SR) are evaluated for Micro channels. Response Surface Methodology (RSM) is used to correlate input and output parameters and mathematical equations have been generated for both responses. The variation of responses due to variations in input parameters has also been studied and shown in the form of surface plots and contour plots. The surface roughness (Ra) of each machined work piece was measured using the Mitutoyo Talysurf (SJ – 201). Each experiment was repeated three times for better results and the average was calculated. It has been found that Ton and Toff parameters are very significant in case of MRR and Ton (Maximum) is most significant in case of surface roughness.
