Controlling vibration phenomena in production
machines is one of the approaches for improving their
efficiency. This also applies to cutting tool vibrations
generated during machining, when the magnitude of
the vibrations directly influences workpiece surface
quality. Continuous efforts to enhance cutting
performance have revealed that machining quality may
be improved if a tool is assisted with high-frequency
vibrations. During the resulting vibration cutting
process [1], the tool periodically loses contact with
the chip leading to a reduction in machining forces,
friction, and temperature in the cutting zone and the
formation of thinner chips, as well as simultaneously
preventing generation of micro-cracks on the cutting
edge and workpiece surface. As a consequence, this
improves cutting stability, surface finish, and tool life
when compared to conventional machining
