This is an old thread but its the closest I could find to what I am looking for.
My question is, what/when is a nonconformity? Therefore what requires an NCR?
I have found lots of information about the subjective nature for determining the need for a CAR. But I have not found anything about what is a nonconformity and when is an NCR required.
Now, before you say that a non conformity is a failure to meet a requirement, realize that when a raw part enters a workcell it does not meet the customer's finished requirement. But we are not going to NCR a raw part that is in process. So I assume we would look to our internal processes for conformity.
To avoid writing NCR's all the time, why can't I write a procedure that allows "rework" within the work cell until the part meets "the requirements" of that procedure?
Here are some examples below:
From ASQ experts:

Example: A welder accidentally causes weld spatter to fly into a tapped hole. The welder cleans out the B-B’s, re-taps the hole and moves on. Generating a non-conformance form should not be necessary in this case as no product was scrapped or made nonconforming.
From Jim Wynne in this thread: "It's not unusual for there to be a "touchup" operation after wave soldering--it's often a normal part of the process, and thus isn't considered rework. Rework happens as a result of nonconformity--a failure to meet requirements. It can involve missing or misplaced components, cold or missing solder joints, etc. Anything that causes an assembly to go backwards in the process should be considered rework."
I saw a different example that said a hole drilled to 9mm that is supposed to be 10mm is a nonconformity. I can see if that product is passed on and found elsewhere then it is a nonconformity. But if the machinist looks at his work and then fixes it by drilling to 10mm, why would that require an NCR?
If a process includes touchup after wave soldering is it a nonconformity that requires an NCR?
What are the extents of touchup? Is a tombstoned component a nonconformity if it is fixed in the workcell and does not leave that operation?
This seems like a very gray area!!
