VIBRATION LIMITS

[[Al...]]

Construction started at our facility and the machinery is sending vibrations through the ground floor where the CMM's are located.

What are the limits of the CMM suspension systems and how would I know the limits are being reached or not?

Probably should contact Zeiss but, you might not get a quick answer.
I believe each CMM type and it's application will differ.

We had to have a special concrete pad poured for our Accura-2 CMM and it is separated from all the concrete around it with 1" rubber filling placed between it and the cut-out section.

Not a true way to test it but, get you a dial indicator and set it up with the needle placed on the granite and if it moves with the vibration, I'd be highly worried.

Simple test (although not accurate) is the Jurassic Park test. Set a glass of water on the granite surface of the CMM. If you see ripples, there's too much vibration.

we put all CMM on vibrating tables, they absorb a lot!
With us the industrial floor had to be made again, the workers came with heavy equipment, I could not determine any effects at the CMM!

Thank you for the feedback, I will pass this on to management.
