Experiments and simulations of ultrasonically assisted turning tool

This paper presents the experimental and simulationinvestigation of ultrasonically assisted turning tool. Bymodeling of immovable fixing of tool we see, that the amplitudesof simulated frequency response are shifted towardsfrequency increasing comparing with experimentalones, and resonant excitation frequencies do not match infew kilohertz. It was estimated, that the model is adequate(experimental and simulated resonant frequencies areclose), when fixing is modeled as elasto-plastic, and ineach node of fixing area springs are modeled, total stiffnessof them is chosen equal to Young’s modulus of grade45 steel.
