I see this so often and I wonder the purpose of placing a reference datum at MMC when the tolerance is shown in RFS.
Let's say, as an example, we have a profile of a surface tolerance of 0.2 mm referencing primary datum A, secondary datum B (RMB) and tertiary datum C (in MMB). What is the...
I just ran across a profile of a surface that had the following tolerance inside the feature control frame:
0.0025|U0.0025
Since this is not outlined in ASME Y14.5M-94, it must be covered with the ISO. Could someone please explain its meaning?
Thanks
