Josh, so just to review and give others a look at the math, if I take a look at my cert for the Global with SP25 we have it showing Uncertainty of 0.462 (microns) to a ball bar length of 754.4.
So dividing the ball bar 754.4 / 1000mm =.7544 unit of measurement
Multiplying the unit of measurement times my uncertainty (.7544 * 0.462) = 0.3485328 microns
So if my smallest tolerance on that machine is 15 microns (times 10% or 0.10) = 0.0015mm =1.5 microns
Since the uncertainty (0.3485328 microns) is less than the 10 times less than my smallest tolerance (1.5 microns) I am good to go.
Am I looking at this correctly per your post or am I missing something here??
TIA, 4/1/96
