Spark machining is one of the non traditional machining processes which is based on thermo electric energy between the specimen and then an electrode. In this work it scrutinizes the machining characteristics of Inconel 600 using Spark machining method with Brass & Copper electrode. Taguchi’s method has been adopted as a strategy of experiments technique for tentative investigation. Certain experiments have been carried out to study the effect of each parameter on the machining characteristics, and then to foretell the optimal choice for each SM parameters such as peak current, pulse on time, pulse off time and then Surface Roughness. Experiments have been designed as per Taguchi’s L16 orthogonal array. Analysis of variance is used to find the level of impact of machining parameters. Machining responses such as the metal removal rate, Tool wear rate, surface roughness the tool was studied while machining the Inconel 600 with copper & Brass electrode. The selection of suitable kind of electrode can reduce the cost of machining. So, in this paper Die-Sinker SM using brass & Copper electrode has been done for optimizing performance parameters and then reducing cost of manufacturing, finally it is found that a Copper electrode give better performance in certain characteristics.
