ABSTRACT:
Method for operating a machine for the relaxation of workpieces, in which the workpiece is subjected to vibrations of selected speeds of a vibrator and in which the selection of the speeds of the vibrator is taken from a measurement which reproduces the vibratory behavior of the workpiece upon excitation by the vibrator within its operating range and in which, for the individual speeds of the vibrator within its operating range, there are determined within a defined harmonics region those harmonics corresponding to those vibrations in the operating range in which resonances or similar stable states of vibration occur and in which connection, for the relaxation of the workpiece, there are selected those speeds which are causal for an accumulating of harmonics in the defined harmonics region.
