I'm putting together the fixture section of our UR5e bracket training, but the archive labels a clamped face-alignment check before and a released hole-spacing failure after, which seems to invite a movement calculation from measurements of different things.
Ask quality to name the measured feature and reference for each check. Are they even intended to be compared as dimensions, or did the before and after labels get added later for the lesson?
The labels were added for the lesson; quality confirmed that face alignment and hole spacing are separate checks, and the identified bracket really did fail the released spacing requirement before correction.
Then the lesson can show those separate stages without calculating a change between them. Keep the released failure and correction attached to that bracket. The misleading comparison does not make the actual failed dimension disappear.
