Not if they are designing and manufacturing things properly. They should know that the final finish will add “A” thickness per surface and design the machining of the part to be “Ax2” undersized before coating it. With a small tolerance for variations in machining and final thickness of the coating.
Joshua on here is more or less needing to work the out part by part for bespoke bits, but when they turn them out in batches hundreds strong!
