Influence of Input Parameters on Characteristics of Electro Chemical Machining Process

Proper selection of manufacturing conditions is one of the most important aspects in the die sinking Electrochemical Machining process, as these conditions determine important characteristics such as Material Removal Rate and Surface Roughness. The material used in the study was LM25Al/10%SiCp composite. Experiments have been carried out to establish an empirical relationship between process parameters and responses in ECM process using Response Surface Methodology. The developed empirical relationships predict the machining conditions within the experimental domain. Analysis of variance (ANOVA) is employed to indicate the level of significance of machining parameters. The contour plots are generated to study the effect of process parameters as well as their interactions. MRR is influenced by applied voltage and tool feed rather than other parameters. Electrolyte concentration has most significant factor on Ra rather than other parameters.
