Optimization of EN24 Steel on EDM Machine using Taguchi &ANOVA Technique

Abstract The accuracy and efficiency of traditional machining process is limited in case of the processed modern materials. So these new developed materials are partial accepted for different application in industry because of its difficulty and costly machining process. Similarly material like EN24 Steels having very good technical properties so it did not economically machine with normally tool by traditional process but such type of constraint do not subject in Electric Discharge Machining. All type of hard material can be machined but the lack of correlation of input parameters for efficient response factors effect on operating cost and quality of products. So to improve accuracy, reduces its operating cost and lower the machining wastage. This paper proposed a research work on EN 24steel with copper electrode. The main focus of this research work to optimize the process parameters like Pulse on time, pulse current, Pulse off time, Duty cycle and Gap voltage for response factors like Tool wear rate (TWR) and Material removal rate (MRR). In the resultant Pulse on time and have large effect in MRR and TWR responses respectively. In this research Taguchi is used to set up the experimental data and ANOVA is used to verify the result for proposed work
