Influence of Additive Alumina Nanopowder on Surface Roughness During WEDM Process

Abstract

The present paper focuses on the wire electrical discharge machining (WEDM) of titanium alloys. It can be considered as an attempt to develop two dielectrics in the WEDM significantly affects the efficiency of machining. This paper explores surface ruggedness during the processing of titanium of various dielectric fluids, including demineralized water and dielectric alumina. The findings show that dielectric alumina as a dielectric produces decreased ruggedness on the surface. Also, surface rudeness is better for demineralized water as the dielectric powder is mixed with non-conductive alumina powder. Many dielectric liquids show that surface ruggedness decreases. Alumina powder and ethylene glycol to dielectric water. A comparative surface roughness analysis for different dielectric fluids was also performed. Using surface roughness to analyze surface roughness is further studied. Conducting a further investigation to use the response surface method (RSM) on surface integrity in each type of the dielectric with the help of better. Hence, WEDM is performed on Ti-6242 to use the designer expert 10 to analysis ANOVA RSM titanium and varying dielectric fluids. From the findings, it is noted that combining non-conductive alumina powder and demineralized water has a significant impact, which decreased of WEDM machined surface of Ti-6242.

Multi-Response Optimization of Al2O3 Nanopowder-Mixed Wire Electrical Discharge Machining Process Parameters of Nitinol Shape Memory Alloy

“…From Figure 4 , by increasing the Al 2 O 3 amount, a decrease in the SR was identified. The addition of nanopowder concentration expands the interelectrode gap and also increases the heat dissipation in the dielectric fluid by forming small craters and reducing the plasma heat flux [ 31 , 61 ]. The addition of Al 2 O 3 nanopowder enhances the flushing of debris from the machining zone.…”
