Ron,
Thanks for the input. That is actually what I started looking at. But the difference in precision and accuracy compared to a traditional bridge type CMM is a factor of 10. Basically the Faro arm is good if you are happy with .001" and does have the advantages of allowing in machine inspection. But a a decent CMM can do .0001" easily.

The other thing that is an issue with the arm is they are far more maintanence intensive to keep accuracy which really means a $3K or so annual contract. Plus there is lots more chance for a whoops that then cost big dollars just because of the portability and the overall design.

So while I thought an arm would be just what I needed, I think research has pointed me to them being more of a specialty item and not the best choice for our first step into a real metrology product.

Thanks,
