Dimensional tolerance MIN question
Dimensional tolerance MIN question
(OP)
If a drawing has specified the following:
UNLESS OTHERWISE SPECIFIED
DIMENSIONS ARE IN INCHES
DECIMAL TOLERANCES
.X +/- .1
.XX +/- .010
.XXX +/- .005
.XXXX +/- .0005
FRACTIONAL TOLERANCES
+/- 1/16
ANGULAR TOLERANCES
+/- 1 deg
FILLET RADII
.005 MAX
And there's a hole dimension called out of ø0.675 MIN. Does that mean the tolerance on that hole is 0.675 +0.005/-0.000?
Thanks in advance!

The MIN specification falls exactly under "UNLESS OTHERWISE SPECIFIED", so it overrides any tolerance specified in the general note.

detrimental to the design". In the "real world", I don't think it is problem because that inspection report mentioned by 3DDave does carry some weight.
