摘要

This work investigates the combined effects of multi-walled carbon nanotubes (MWCNTs) weight% (wt%), aspect ratio (AR), and surfactant content on tool wear during MQL machining using nanofluids. While advancements have been made in the application of nanofluids in machining processes, the interplay between these parameters and their influence on both nanofluids stability and tool wear has not been systematically examined. The turning operation of AISI 304 austenitic stainless steel revealed that nanofluid combinations with lower wt% and AR of MWCNTs improved tool wear performance. However, excessive surfactant content triggered a bridging mechanism that reduced nanofluid effectiveness, ultimately compromising tool wear. These findings suggest that careful optimization of nanofluids composition can lead to substantial improvements in machining efficiency and tool life.
