Electrical discharge machining (EDM) is the thermal erosion process in which metal is removed by a series of recurring electrical discharges between an electrode and a conductive work piece, submerged in a dielectric fluid. EDM is one of the option for manufacturing, geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining processes. Its unique feature of using thermal energy to machine electrically conductive parts regardless of hardness has been its distinctive advantage in the manufacture of mould, die, automotive, aerospace and surgical components. In this work, experimental investigation has been carried out with coated electrodes for machining HCHCr die steel. Standard copper electrode is coated with different coating material. Experiments were conducted with three types of electrodes: standard copper electrode, TiN coated copper electrode and TiAlN coated copper electrode. The influence of EDM parameters is studied on two of the most important technological characteristics: material removal rate (MRR) and electrode wear (EW). It was observed that TiN coated electrode shows better results as compared to other electrode.
