Research on the cutting performance and contact behavior of a new bionic saw blade segment

Abstract

Abstract Diamond circular saw blades, integral in industries such as aerospace, nuclear energy, and construction engineering, face challenges including high cutting forces and significant tool wear, which often fall short of modern engineering requirements. To address these issues, this study explores the application of the non-smooth morphology, inspired by the surface of Scapharca subcrenata, known for their friction-reducing and wear-resistant properties. This morphology is applied to the tool-chip contact area of the saw teeth. Comparative experiments, conducted through sawing simulations, reveal that the optimized tool demonstrates improvements in sawing force, equivalent stress, and material removal rate compared to conventional tools. These findings offer valuable insights for further research into the wear resistance and drag reduction optimization of diamond circular saw blades.
