Inspection of drawing when part is circular
Inspection of drawing when part is circular
(OP)
I have part in circular shape with holes. I would like to know how the holes in the part inspected since the part is dont have GD & T to constrain part.
How the inspector will hold the part to inspect X, Y Dimension.
I have attached drawing

RE: Inspection of drawing when part is circular
1. Have both of the center of the circles defined in the drawing (you currently only show the smaller circle).
2. Provide the radii for both of the circular pieces of the part
3. Align the part so that the centers of the 2 circular pieces are aligned vertically (it's offset in the drawing)
4. Show the distances from the centerline to the point where the 2 circular pieces meet
5. Show the diameter/radius of the holes.
6. Revise the distances to the centers of the holes based upon realignment of the part. I'd also align them based upon the center of the larger circular piece instead of the smaller piece as well.

So, the question really must be, "what exactly are you supposed to be inspecting?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

2) your dimensions locate things with respect to each other (ie what's the problem) ?
3) you could dim'n the center of the grow-out circle with respect to the centers of the two small holes.
agree that this is probably not the most relevant forum ...

How the inspector will hold the part to inspect X, Y Dimension.of holes and profile.
RE: Inspection of drawing when part is circular
there are many ways to inspect the part ... if you can draw a dimension between two physical locations, they have check it. for installations on the outside of the fuselage, we'll dimension from a seat track datum inside the fuselage ... lord knows how they check that !
an easy way would be to make a -ve part (make a hole in a plate to match the outline of your part), "go/no go" gauge.
it'll depend on how many of these you're making, and how critical the dim'ns are.
btw, you should tolerance your dim'ns. maybe there's a standard drawing tolerance ?
