Having a question with a program. My part has a profile callout of .040. The report shows +.020 -.020... And my results say .022, and is RED... I'm not seeing how a profile of .040 is out of tolerance when the result is .022?? Something just doesn't seem right....?
ASME14.5 profile is as follows:
Condition 1: If all point are positive error the reported value is: Nominal "0" to your worst positive error. Example(profile of .04 AKA +.02-+.02) no negative error... worst positive error of 0.022 will result in a failing profile of .022
Condition 2: If all point are negative error the reported value is: Nominal "0" to your worst negative error. Example(profile of .04 AKA +.02-+.02) no positive error... worst negative error of 0.022 will result in a failing profile of .022
Condition 3: Error is both positive and negative: reports the difference between the largest negative and highest positive. Example(profile of .04 AKA +.02-+.02) 0.002 worst negative error... worst positive error of 0.019 will result in a passing profile of .021
Lastly... since I have the older software, which shows nominal .000/ tolerance +.01, -.01, (for the profile of .020). Instead of sending the CMM print-out, an inspection report was filled out. And, as the tolerance , wrote profile of .020 and behind the results was .012 and stated oversized. Since the tolerance on the inspection report was stating "profile of .020", I think, in the results should have been .024 (double .012)?? Am I off my rocker?
