1. A method of cleaning powder residues from an at least partly additively manufactured component thereby avoiding resonance damage, the method comprising:
cleaning the powder via a cleaning device, wherein
a machine plate and the at least partly additively manufactured component being arranged thereon are excited to mechanical oscillation with a set resonant frequency of the machine plate during a cleaning process by a vibration actuator of the cleaning device to release the powder residues from the at least partly additively manufactured component, and
the machine plate of the cleaning device and the at least partly additively manufactured component arranged thereon are pivoted around at least one axis during the cleaning step by a pivoting apparatus of the cleaning device to cause the powder residues of the at least partly additively manufactured component to flow away,
wherein, before carrying out the cleaning process, a resonant frequency of the machine plate is set to the set resonant frequency by arranging a mass element on a securing element of the machine plate, wherein
the set resonant frequency is determined according to a predetermined selection method depending on at least one resonant frequency of the component, and the set resonant frequency of the machine plate has a greater margin separating it from the at least one resonance frequency of the at least partly additively manufactured component than does the resonant frequency of the machine plate without the arranged mass element, and
at least one parameter of the mass element is ascertained according to a predetermined ascertaining method depending on the set resonant frequency of the machine plate.
