“…The latter, which is of particular interest to the present research, is due to the poor quality of those micro-holes in the tool plate. Kishore et al [7] explored LBµM as an auxiliary process used for fabricating tool plates with the desired shape micro-holes in different arrangements. Both the processes were facilitated on a single CNC machine tool with an axial resolution of 0.1 µm.…”

This paper focuses on the fabrication of high-quality novel products using a µEDM process variant called Reverse-µEDM. The tool plate required for the Reverse-µEDM is fabricated using Nd: YAG-based laser beam micromachining (LBµM) at the optimized process parameters. The Grey relation analysis technique is used for optimizing LBµM parameters for producing tool plates with arrayed micro-holes in elliptical and droplet profiles. Titanium sheets of 0.5 mm thickness were used for such micro-holes, which can be used as a Reverse-µEDM tool. The duty cycle (a combination of pulse width and frequency) and current percentage are considered as significant input process parameters for the LBµM affecting the quality of the micro-holes. A duty cycle of 1.25% and a current of 20% were found to be an optimal setting for the fabrication of burr-free shallow striation micro-holes with a minimal dimensional error. Thereafter, analogous protrusions of high dimensional accuracy and minimum deterioration were produced by Reverse-µEDM using the LBµM fabricated tool plates.

Reverse micro electrical discharge machining (reverse µEDM) is becoming more popular as a novel method for creating array microelectrodes with a high aspect ratio without pro le restrictions. Surface roughness is an essential quality characteristic or parameter determining the product's nal shape and is more determinant when the size of the product is small. The objective of this work is to create a mathematical model based on dimensional analysis that uses Buckingham's µ-theorem to quantify the surface roughness of microrods. Surface roughness has been explored through experiments based on the Taguchi design, considering the process parameters such as voltage, feed, capacitance, ushing pressure, and material properties (thermal conductivity, electrical conductivity, melting temperature, and speci c heat). The surface roughness of tungsten carbide (WC) micro rods increases by approx. 58% when the capacitance increases from 10nF to 100nF. FESEM is used to analyze the crater size variation of WC micro rods. The surface roughness predicted by dimensional analysis supports the experimental results with an error of 3.45%.
