So if the CMM room temp. changes from 70-80 degrees, would that mean that 15.000" dia would actually grow up to .001" ??? Yet the result would still be 15.000 ????
Dan, I am not sure I fully understand how the temp. Effects the measurments. So using my example of 15.000” diameter where the temp of a cmm room is 80 degrees using the coefficient of 6.5. Means that the part can grow up to .001.. so when the part is measured on the CMM and result is 15.001 what does it mean?
The way I was tought is that if the part and the gage expand at the same rate, then the readings would not be effected.
When cmm is being used, does this still applies? Can you explain this?
