Help with lining up hole with groove
Help with lining up hole with groove
(OP)
Hello,
On a thick walled pipe there is a radial groove on the inside of the pipe. The groove is dimensioned by a radius and the depth is defined by a dimension outward from the inner diameter of the pipe to the top of the groove. The radius is larger than the dimension from the inner wall so the radius is not a feature of size. The centerline of the groove is dimensioned axially with a toleranced dimension from the end of the pipe.
I would like to drill a hole at 45 deg into the pipe and have the hole line up within .010 positionally with the groove.
Can anyone advise on how to set up the GD&T, datums and dimensions to ensure the hole lines up perfectly (.010) with the groove?

Without fully understanding it, you may be able to use position on the hole and surface profile on the groove.
KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?
RE: Help with lining up hole with groove
To address the actual question; You can call the width of the slot a datum and then position the hole to it. You will need to set up other datum structure but until you post a simple sketch or something to better illustrate your dilemma, I can't really tell what you're trying to achieve.
