Wire surface profile call out confusion.

RobOntario
Hello all

I have a surface profile call out for 3 mm, the program uses 1.5 -1.5 and deviation 3.0 to check all those hits. My question is whether unilateral profile should be only about max min deviation about 3 mm?
Can I use 3 mm and -3 mm to check the hits M value and relays on deviation only?

Thank you

  • Since you are using Legacy dimensioning on the profile, you will need to report our the MAX and MIN deviations, which are in the textual analysis. I do not see the arrow that the profile callout is pointing at to see if it is a bilateral or unilateral tolerance. Either way, you will not have a +/- 3 tolerance.

    What is the standard on the print? ASME? 1994? 2009? 2018? ISO? This will affect how you report the profile.
