1) We have checked the WIP parts and found no parts in WIP (work in progress)
2) We have checked the stock parts and found one part in FG and checked the thickness that shows the thickness variation and measures out of limit.
3) During machining warpage existing that effects to thickness of the part.
4) During CMM inspection, we hold the part in both the sides that effects to original shape and might be part shrink.
5) Drawing doesn't calls thickness directly that to be extracted from model during that process we missed to check against model.
