Limit curves of permissible floor vibrations at the installation site
Explanation for the diagrams
The following diagrams shown the frequency-dependent limit values for the coordinate measuring machine. However,
these are non-binding and apply only to the specified combination of size and probe. Furthermore, the following re-
quirements must be met (otherwise minor deviations must be expected and a certain distance to the limit values
should be maintained):
–
No loading workpieces >10% of CMM weight
–
Stylus tip distance <100 mm relative to the stylus mount on contact probes
If there are any harmonic floor vibrations (sinusoidal oscillations, e.g. caused by nearby, rotating machine tools), the
limit values must be compared with the square mean (RMS value) of the measured floor vibrations. If there are any
pulse-shaped floor vibrations (e.g. caused by a nearby press), the limit values must be compared with the maximum
value (peak hold) of the measured floor vibrations. If there are two peaks near each other in the frequency spectrum
(regardless of the excitation direction), the amplitudes of these peaks must be added and compared with the limit
curves.
If none of the given diagrams applies to your configuration, the diagrams for other sizes can be used for orientation.
