Actually sound like a good idea to me. If you have a progressive die making a left and right part, your process is identical for both parts. They are made at the same time, in the same die, in the same press, with the same material, undergo the same production flow, have the same dimensional checks, have the same FEMA, same Control Plan. May as well have the same PPAP. What value is there in doing to seperate piles of the same documentation?
