Our UR5e collar trial has two pad candidates and two very confident opinions about the marks. The photographs use different lamps, and nobody recorded the collars before handling. I need a comparison quality will actually use, including whether the softer candidate holds and releases properly.
Quality has now chosen the normal inspection station and kept accepted and rejected collar examples. We're checking identified collars before handling there; the old photographs are out of the comparison.
Yes, Zara, quality selected the same accepted range for both. The softer candidate left less visible contact marking, but two collars hung on during release. Tooling has stopped that candidate's trial to investigate the contact arrangement.
