I've got physical good and bad parts now, and the lip isn't hidden in the picture, so this ought to be less of a headache. It isn't. One faceplate has a faint line that quality accepts, but our draft UR5e camera exercise flags it harder than the rejected one.
I don't want to bin the accepted example just because it's awkward. Do I put it beside the reject as a comparison, or does that confuse people before we've even commissioned the cell?
Keep it beside the reject. That awkward accepted part is probably your most useful example. I'd put the actual quality decision and its reason beside each image, then ask somebody to explain the difference back to you. If they can only say one line looks brighter, you've found a gap in the exercise before spending anything on the camera.
We used both. Turns out I'd written 'line visible' in the draft reject note, which was basically an invitation to reject both of them. Quality helped replace that with the actual finish criterion and the tutor could explain the distinction without my commentary. Keeping the annoying plate.
