Abstract

Shear thickening fluid (STF) is a kind of smart material showing increasing viscosity under loading. This unique behavior is benefitted in various applications however, STF usage in machining tools has not been investigated in literature. In this study, a novel tool was designed by integrating STF into conventional cutting tools for turning operations. Thanks to this design, the non-Newtonian rheology of STF contributes to the vibration damping properties of cutting tools and thereby suppressing the chatter vibrations during machining operations. For this reason, STF integrated cutting tools provide enhanced stability in the operations, which leads to an improvement in the surface quality of workpieces.
