“…As machining progresses, the supplied current decreases due to the increased IEG. 26 As the tool is rotated, the debris particles are effectively flushed from the machining zone, which avoids the formation of stray current. For applied voltages 3V and 5V, the slopes (rate of decrease in current over time) obtained are less than 7 V and 10 V. Hence, the experiments are conducted at 5V for the fabricated micro tool, as shown in Figure 7.…”

Electrochemical micromachining (EMM) uses anodic dissolution in the range of microns to remove material. Complex shapes that are difficult to machine on hard materials can be fabricated easily with the help of EMM without any stresses on the workpiece surface and no tool wear. Fabrication of microfeatures on microdevices is a critical issue in modern technologies. For the fabrication of microfeatures, precise micro-tools have to be fabricated. In this present study, EMM milling is used for the fabrication of micro-tools. For this, an EMM setup has been designed. Tungsten carbide tools with an initial diameter of 520 µm have been selected and are electrochemically machined to reduce their diameter. The tool and workpiece are connected as anode and cathode, respectively. The electrolyte solution used for this investigation is sodium nitrate. A comparative analysis of the effect of tool rotation over both machining accuracy and surface finish has been performed.
