Optimization of Processing Parameters in ECM of Die Tool Steel Using Nanofluid by Multiobjective Genetic Algorithm

Abstract: Formation of spikes prevents achievement of the better material removal rate (MRR) and surface finish while using plain NaNO3 aqueous electrolyte in electrochemical machining (ECM) of die tool steel. Hence this research work attempts to minimize the formation of spikes in the selected workpiece of high carbon high chromium die tool steel using copper nanoparticles suspended in NaNO3 aqueous electrolyte, that is, nanofluid. The selected influencing parameters are applied voltage and electrolyte discharge rate w… Show more

“…Dimensional electrochemical machining (DECM) [3,17,18,19] It is used mainly in the formation of details in difficult-toprocess materials with expressed high requirements for the accuracy of the shape and the mutual position of the surfaces, such as:  Molding of deep holes with special configuration (snow sockets, weapons barrels) [3,17,18,19] .  Creation of working spaces in tools for injectable molding of polymers and metals [20,21,22] .…”

“…Many researches have also been conducted in the past using above methodologies in relation to metals, metal matrix composites, and nanocomposites. 10 -24 Elango et al 25 attempted to find the optimum control parameters for turning Delrin through TLBO algorithm. But the drilling characteristics of Delrin have not yet been addressed, which look to be a high requirement for industrial applications.…”

“…The optimum results given by the experiment are as follows 8V voltage and 0.3mm/min feed rate and 217A current are most appropriate and momentous to achieve utmost surface finish with NaNO3 electrolyte solution. V. Sathiyamoorthy et al (2015) attempted to diminish the formation of spikes in the work piece of high carbon and high chromium die tool steel using nano particles of copper floating in plain NaNO3 electrolyte. They used Design expert 7.0 software to developed the mathematical models for getting the response like MRR and SR and after that multi-objective genetic algorithm in MATLAB was used for the best probable combination for accomplishing the maximum MRR and minimum SR. After comparing the result from design expert 7.0 to the optimum results obtained by using multi-objective genetic algorithm (MOGA) the conclusion come that the distinction from the predicted performance is less than 4% which verify the composite popularity of the developed models.…”
