Yep, that is exactly what I am refering to Stij. We have a large number of CMM's on our shop floor, and several more in the lab. My concern right now is the differences between the shop floor machines (which control production adjustments) and the lab machines (which control final audits, PPAP layouts, etc). Obviously if there is poor correlation then there will be a problem at the end of the process - just looking for the best way to set up the trials and evaluate the results.
