The closer your inspection the more defects you will find, the more rework you do the possible cost you will add and the potential increase of damage you could do to your products if rework is not up to a machine copyable standard. "Is there any in

most, possibly all of our clients, don't specify this kind of thing even when they are in fields where you might expect they should and should be aware of them. However if you cherry pick a couple of class 2 requirements such as offset and joint widt
