We have always tried to keep the CMM rooms as close to 68 F as possible and just let the parts soak to get to room temp, then measure them. We have a customer, a major aerospace company, who is now asking us how we compensate for temperature. It's possible that our current method will be acceptable as long as we have a documented procedure for doing it.
Just in case it's not satisfactory, I want to query the gurus out there about how they use temp comp, in case the customer wants us to use it.
Do you let the controller check the temperature and do all the compensation, or do you type in the temperature manually?
If you do it manually, do you type in values for the X,Y,Z axes? Do the scales grow with temperature? If they do and you only comp the part, wouldn't that cause a faulty reading?
If you have answers to any or all of these, let me know. If you have any other considerations that we should be aware of, feel free to let me know(as if anyone here would actually hold back anything
)
Thank you in advance.
