Application of Abrasive Water Jet Machining in Fabricating Micro Tools for Edm for Producing Array of Square Holes

In the field of Abrasive Water Jet (AWJ) machining, the current focus is on the fabrication of complex threedimensional features. The current work is aimed at using this strategy to manufacture micro-tools for machining arrays of square holes using Electric Discharge Machining (EDM). Based on selected parameters of AWJ process(step over, traverse speed, path strategy),micro tools were fabricated on brass sheet of 6 mm thickness.The performance of such fabricatedtool was investigated by performing experiments on EDM machine to make arrays of square blind holes( texture ) on stainless steel and Ti-6Al-4V alloy sheet. The depth of texture was measured through 3D profilometer of FOV (2x) and objective (5x) embedded with vision 64 software.The textured square holes were obtained and its depth was achieved in the range of 10 to 60 microns and thecorresponding depth obtained of the texture is less on titanium. Discrepancy between the tool dimension (square) and work piece (textured) was found because of the tool wear on the electrode.
