Titanium and its alloys are utilised in a wide range of industries due to their excellent properties such as high tensile strength, fatigue resistance, high strength-to-weight ratio, corrosion resistance, toughness at higher temperatures, and the ability to sustain high temperatures. WEDM has emerged as one of the most extensively utilised processes for creating precise geometries in refractory materials such as titanium alloy in recent years. The Titanium Grade 12 alloy is machined utilising the WEDM process in this experiment. In WEDM, both Mo wire and Zinc coated brass wire are used as electrodes. The effect of Titanium Grade 12 alloy WEDM with Mo Wire and Zn coated brass wire on surface roughness (SR) was investigated. The surface of a Titanium Grade 12 alloy that had been worked on with a wire electrical discharge machine (WEDM) was examined with a scanning electron microscope. The images that were produced by scanning electron microscopy show that the substance had uniform solidification and a columnar grain structure along the build direction. This was discovered by observing the structure of the grains. It has been observed that the SR rises along with an increase in TON. Titanium Grade 12 alloy with Mo wire and Zn coated brass wire both have minimum SR values of 2.131μm and 1.763μm at a TON of 20μs. It has come to our attention that a higher TOFF results in a lower SR value. Titanium Grade 12 alloy with Mo wire and Zn coated brass wire both have a minimum SR of 2.689μm and 1.618μm at a TOFF of 20μs. It has come to our attention that an increase in the peak current causes a rise in the SR value. The minimal SR is reached at a peak current of 2A and is equivalent to 2.071μm and 1.689μm for Titanium Grade 12 alloy with Mo wire and Zn coated brass wire respectively This is the case when the SR is measured at its lowest point.
