What is standard for ID radii on drawings?
(OP)
We are having a discussion with a customer that wanted a sharp corner or at least .008 rad or less in an ID counterbore. This was not noted on their drawing. It was drawn per ansi/asme Y14.5 1994. They do have a not to break all sharp edges to .015. Is there a standard for sharp corners when nothing is noted? thanks

Envelope principle.

Maybe section 2.7, with a bit of 1.4m thrown in.
In essence, if the bore dia is at MMC it must be sharp corner. As the diameter moves from MMC toward LMC this unused tolerance would allow small radii.
