Abstract

This thesis explores the effectiveness of aluminum oxide (Al2O3) and copper oxide (CuO) nanoparticles as coolants in metal cutting on a lathe machine. It compares these nanofluids to conventional cutting fluids in terms of machinability. Experiments were conducted with stainless steel workpieces using conventional fluids and nanofluids with 0.2%, 0.5%, and 0.8% concentrations of Al2O3 and CuO nanoparticles. The study assessed temperature, tensile strength, hardness, tool wear, and chip morphology.

Findings indicate that nanofluids reduce temperatures and decrease tool wear more effectively than conventional fluids. For Al2O3, optimal improvements were observed at 5% concentration, while higher concentrations led to deteriorations. CuO nanoparticles showed continuous reductions in temperature up to 8%, with increased tensile load and hardness at this concentration. Chips produced with nanofluids were longer and less fragmented.

Overall, nanofluids demonstrate potential as sustainable coolants, offering benefits over traditional fluids. Further research is needed to optimize nanofluid formulations and expand their applications.
