Impact of Magnetic Field on Machining Rate and Surface Roughness in Electrochemical Machining

Abstract:

Electrochemical Machining (ECM) is a modern metal working process that make it possible to machine products that are challenging or even impossible to create using traditional machining methods. This study aims to explore how surface roughness and machining rate in ECM are influenced by magnetic field on the metal matrix composite with different machining process input. Neodymium magnets were employed to generate the magnetic field during experiments. The workpiece material used in this experiment is aluminum 6061 alloy, Al-B4C, Al-SiC and the tool material is copper. The input parameter used in this experiment was varying such as electrolyte concentration, voltage, gap, and type of material. Minitab software was used to analyze the results and orthogonal arrays are used in the Taguchi design of the experiment. The results showed that in all experiments, the magneto hydrodynamic effect both reduces surface roughness and increases the machining rate. Furthermore, the Al6061 alloy exhibited the smoothest surface finish and the highest machining rate.
