Claim 9:
10. An additive manufacturing machine comprising:
a spreader to dispense a build material to a target surface;
a sensor to output measurement data based on a measurement of a vibrational characteristic of the spreader during an operation of the spreader; and
a controller to:
identify, based on the measurement data from the sensor, a resonant frequency associated with the spreader at which the spreader is not to be vibrated;
identify, based on the measurement data from the sensor, a further frequency at which an amplitude of a vibration of the spreader is below a threshold; and
control, based on identifying the resonant frequency associated with the spreader and based on identifying the further frequency at which the amplitude of the vibration of the spreader is below the threshold, a sweep of a frequency of vibration of the spreader across a range of frequencies.
