It looks like, if that's a round feature and all things given were nominal, you would have +/- .0004 on the diameter at the end of the cone. Yea, kinda tight.
That is what I get (just about 0.0007" angularity). Using rule of thumb of 10 to 1 the cmm would need to be theoretically capable of discriminating to 70 millionths. Tight.
