A suitable selection of machining parameters for the electrical discharge machining process relies heavily on the operators’ technologies and experience because of their numerous and diverse range. Environmental sustainability in machining requires that the energy and carbon footprint of machined products be optimize Hence machining becomes inevitable. In this work, machinability behavior of different combination of machining parameter is using on TiC during Electric Chemical Machining. The input parameters of the GRA model are Feed Rate (mm/min) Flow rate (l/min), Electrolyte Concentration (g/l). The output parameters of the model are MRR, and Overcut. it depicts percentage contribution of each factor with respect to over cut and it depicts that electrolyte flow rate and electrolyte concentration are contributing factor more and tool feed rate plays nominal role with respect to overcut and MRR.
