Electrical Discharge Machining is used to machine complex shapes with a high accuracy and materials such as carbides, heat resistant and super alloys which are difficult to machine. Dies are tools used to cut or shape materials into a solid product. EDM method is used to create these dies, despite the size or commonness of the shape needed. In this study, influence of electrodes and technological parameters including (curent (I), pluse on time (Ton) and pulse off time (Toff)) on machining productivity in EDM with coated and uncoated electrodes is investigated. SKD61 material is used to studied, electrode Cu, TiN and TiAlN-coated electrodes are also investigated. Taguchi method is used to design the experiment. The experimental results showed influence degree of technological parameters on MRR.
