I would appreciate the help of a metrologist or otherwise GD&T guru interpreting the exact meaning of this drawing excerpt.
I’m pretty confident with my understanding of the majority, but some confirmation would be great. What I have no clue on is the “DEP + 1°”. This one is a first for me.
EDIT (ADDED): On the same drawing, I just noticed an “AC” to the right of a surface roughness symbol under the top bar. I couldn’t find a good reference that mentioned this.
EDIT (ADDED): I mentioned GD&T above, but I believe this may be ISO GPS. The image shows a machined hole in a permanent mold aluminum casting.
Thank you!
