The first part of this paper introduces a new control algorithm using dynamic machine models to adapt feedforward signals to mechanical resonances. Especially for machine tool applications where the excitation of resonances is mainly caused by the acceleration and deceleration forces this new approach results in a significant increase of machine dynamics. Within the second part of this contribution a feedback control method is outlined allowing an active damping of mechanical resonances using servo motors of the feed axes. Applications with high process forces exciting mechanical eigenfrequencies may be restricted by insufficiant damping of critical eigenmodes. Consequently, an active damping of these modes results in a productivity increase.
