Quick question About ISO.....

KIRBSTER269
If a Blueprint calls for ASME Y14.5 wouldn't this be the standard rules apply. How would I know if and when to apply ISO? I have yet to see anything on a blueprint stating this. The reason I bring this up is for the good old Profile callout. Before I make an argument, I want to cover all my resources. Customer already claims in an email that PC-DMIS is not capable of doing this. I and everyone on here already that's horse_S_H_I_T. But its Friday and I'm ready to P_I_S_S someone off

  • Actual Value. For Both unilateral and bilateral profile tolerances two actuals are necessarily calculated: one for surface variations in the positive direction and one for the negative direction. For each direction, the actual value of profile is the smallest intermediate tolerance to which the surface conforms. Note that no single actual value may be calculated for comparison to the tolerance value in the feature control frame, except in the case of unilateral profile tolerances.

    , I'm not defending PC-DMIS by any right. I have been to 3 different GD&T classes. Didn't go to PC-DMIS classes to learn GD&T, went there to learn PC-DMIS. Not bragging or gloating here. 82 version, 94, and 09. Different instructors. Same results on the ASME Standard. Now after actually reading this from ASME standard. It tells me to do the same. If you see it differently, that's cool. You think your right, I know your wrong. Rolling eyes but I do still agree with you on T value is the true way to go. Oh and yes that is out of the book. I will copy it, and post it later so others can interpret it the way they want. I will say this again the word SUM, usually means ADDITION
