So the issue is we have a part that is a cylinder with a non flat surface for the main datum. When you set it on the surface plate it will rock. The engineers say that does not matter as the measurement allows for the rocking to fall within the measurement envelope. I say it falls out of tolerance due to it not being flat so the perp of the axis is no longer perfectly perp from the datum. I have done this on the height gauge and found the center axis is not perp due to the datum not being flat. i am calling the part out. I am told i am wrong. thought feelings etc.
Correction the face that is not flat is datum B datum A is a center line.
So A isn't straight ? The call out is the face ( B ) perp to A. The small angle , based on the leader line doesnt look like it should be included in B ? Remember the callout. B perp to A. A perp to B will give you a different ( and incorrect ) result for this print requirement.
Is A called out somewhere else? RIght now, it's on an axis line, and that doesn't exist. And B appears to be a flat surface. Are you talking about Dim 13?
