Message No. 21800, Started by sdicarlo on 08/23/12

I have a 90 degree countersink located at the bottom of a 1.125 dia. x 2.35 deep. It is used as a seating surface for a valve. It requires a 32 finish and is measured with a 1.1875 dia. gage ball.

The 1.125 dia. is marked datum A.

Which geo tol would be correct for this application?

a) profile/.001/A

b)angularity/.001/A
