Hi need some help from you guys 
I have a customer complaint about a hole that the customer says is out of tolerance but i cant agree with him about that.
Here is the situation: The hole is a stamped hole in a plain steel material 4mm thick. On the drawing it says diameter 10 +/- 0,2 mm and nothing more, no cylindricity or perpendicularity just the diameter. We all know that a stamped hole has its cutting zone and it's shearing zone (I think it's called that) when the material more or less is ripping apart
So what he has done is that he has measured the hole (With the tips of a slide caliper) from the cutting side approx 0,5-0,8mm in to the hole and that side is 9,9mm in diameter, then he has done the same way on the shearing side and measured it to 10,56, and that's why he says it is out of tolerance, the hole is more or less conical (As always on a stamped part if not using fine stamping). but out from my perspective i would say that to determined the dimensional of the hole, out from what the drawing says i need to pass the biggest cylinder through the entire hole, and that results in that the hole is 9,9mm, my point is that you can't measure a part of the hole to say it is out of spec you need to measure the entire hole
Am i correct in my judgement or am i wrong?
Please if you can help me in this and perhaps point out the standard on how to determined the diameter of the hole i would Appreciate it very much
Best regards Tommy
