Study of electrode speed on material removal rate in electrochemical machining (ECM) process.

Electrochemical machining (ECM) is a nontraditional machining technology that is used to operate the most challenging materials that are tough to work with in traditional machining. The results of this research were utilized to investigate the effects of various parameters on Material Removal Rate (MRR). This research uses stainless steel LN1 as the workpiece material, copper as the tool material and NaCl as the solution. Electrode speed, voltage and solution concentration were employed as inputs, whereas Material Removal Rate (MRR) was used as an output in this study. Electrochemical machining trials with speeds of 50, 75 and 100 rpm. concentrations of 5, 10 and 15 g/l, voltages of 10, 20 and 30 volts. The full factorial design which was carried out with the MINITAB 19 program, yielded the best results. Experiments have shown that at 100 rpm, 15 g/l and 30 V, The best Material Removal Rate (0.242) g/min is attained. The material removal rate is predicted using a coefficient determination (R-sq) (96.87 percent). [ABSTRACT FROM AUTHOR]
