Electro Chemical Machining (ECM) allowed success in the production of newer materials, especially for the aerospace and biomedical applications. Using ECM technology, complicated cuts can be made through difficult – to – machine hard materials. This paper highlights the development of mathematical models for correlating the interactive and higher order influences of various machining parameters on the dominant the machining criteria, i.e., the material removal rate and the surface roughness through response surface methodology (RSM), utilizing relevant experimental data as obtained through experimentation. Validity and correctiveness of the developed mathematical models have also been tested through Analysis of Variance (ANOVA). The present work also highlights the development of mathematical models for analyzing the effect of various process parameters such as, current, voltage, flow rate and gap width on the material removal rate and surface roughness.
