I have asked for a visible seating check on our UR5e sensor-bracket nest. The harder question: which contacts should locate it before the clamp closes?
Have the designer relate each intended locating contact to the bracket drawing, then compare identified samples without using clamp force to hide a rock; the visible check needs a sound seating condition to recognise.
Does the proposed nest contact the formed bend as well as the intended flat faces? That may be useful for the designer to see in your bench photographs.
