Another main issue of robot machining is the effect
of vibrations to the produced surface quality. Due to
the low natural frequency of articulated robot body,
resonance can occur due to machining process
vibrations. Oki et Al., focusing in the cutting of
workpieces from an extruded aluminum alloy,
assessed the effect of vibrations on the
characteristics of end milling operation. Their
experiments proved that during high-speed cutting,
the generated process frequency is high enough
without resonance issues, ensuring stable and
normal end milling with restrained chatter and
vibration of the articulated robot
