Owing to its hardenable nature and corrosive resistant, Titanium is mainly utilized in fabricating turbine blade applications. Since it is very tough to creating the complex shape on this material by using traditional machining process. Generally micro holes are produced over the turbine blades to reduce the heat using EDM and LBM process. These processes can produce a heat affected zone over the machining surface and higher operating cost. The target of this present study was to make a micro hole on titanium by using electro chemical micro machining process and also attempt to identify the performance of nickel coated copper electrode for embellishing the ECM process. Since the process involves with no tool wear and less heat affect zone, it is possible to improve the machinability of the material. Titanium specimens have been machined using ECM process with uncoated copper electrode and nickel coated electrode under different process parameters combinations. From the experimental results, the better MRR and surface finish were observed from the nickel coated copper electrode.
