Experimental study on electrochemical micromachining

Influence of tool vibration on machining performance in electrochemical micro-machining of copper

“…The MRR and accuracy was observed for various sets of experiments with different combinations of process parameters. It was found from the previous research that with 3 V, 55 Hz frequency power supply and around 20 g/l electrolyte concentration desired machining accuracy can be achieved with highest possible amount of material removal [11]. So applied machining voltage of 3 V and power supply frequency of 55 Hz were selected for experiments.…”

A comparative study of surface integrity of Ti–6Al–4V alloy machined by EDM and AECG

“…The conductive aqueous solution should not only be capable of generating current flow between two electrodes, but also of flushing away the dissolution of the metal from the grinding zone. Related research by Bhattacharyya et al [11] showed that the roughness of electrochemical machined surfaces increased accompanying the decrease of electrolyte flow rate since the higher concentration of reaction products could not be removed properly due to narrow small inter-electrode gap and caused to deposit in machining zone, so that the workpiece material no longer dissolves properly. In our case, as can be seen from Fig.…”

Genetic algorithm parameters optimization for electrochemical machining using response surface methodology

“…Genetic algorithm normally starts with a preliminary population of chromosomes, which are randomly produced and based on several algorithms, other policies and Socratics. Bhattacharyya et al (2005) highlighted various electrochemical micro-machining parameters like machining voltage, frequency, pulse period and electrolyte concentration and their influences on the Material Removal Rate (MRR), surface finish and accuracy in infinitesimal field. His study shows that 3V machining voltage, 20 g/l electrolyte concentration and 55 Hz frequency are optimal values of Electro chemical machining that can augment the accurateness with the uppermost possible amount of material removed (MRR).…”
