Our training fixture looked unchanged until we put a straightedge on its mounting plate. I'd start with the tray seating and gripper contacts under the maintenance procedure, and preserve the current offsets before anybody helpfully edits them again.
6分The offsets are saved, Leo; by unchanged I meant visually similar, not measured against the original fixture drawing.
20分Does the housing sit square before the fingers close, or does the tilt first appear while it is being gripped?
7分I'd keep a few troublesome housings aside too. We once blamed a nest for a molded lip that had changed, then spent a pleasing amount of time making a good nest worse.
22分Lin, did you have earlier parts to compare with? I have seen retained samples used for dimensions, but I do not know how well they represented normal production variation.
4分Only a handful, John. Enough to spot the changed lip, not enough to call the whole old supply consistent. Quality had to take that comparison further.
6分I would avoid combining all the pickup edits into a single correction history. If some followed tooling work and others followed tray changes, the dates may help you choose useful comparisons, though they won't prove the cause.
13分Mia, the tilt becomes visible at closure in our recorded cycle; Zara, two offset changes followed pad replacement, but the notes do not identify the pad version.
13分Are the fitted pads actually a matched pair? I'd check their references before changing points.
11分Stores may have the issue record even when the maintenance note is thin, although I would compare the fitted markings rather than assume everything issued was installed.
2分With tilt appearing at closure I'd give the contacts priority over an arm repeatability claim. Still check the seating, Naomi; the fingers can reveal a part that was resting awkwardly before they touched it.
25分Jo and Dinesh, the pads have matching references and stores confirms the same pair was issued; one contact face is visibly more worn, which maintenance is measuring now.
12分Matching references at least remove one ambiguity. Could uneven wear come from the housing arriving tilted, rather than being the first cause? I would not know which came first from the worn face alone.
14分Yes, John, that's why I'd keep the incoming parts in the investigation. A new pair could briefly disguise the same awkward seating and send Naomi back here after another batch.
18分Who is covering the work while maintenance checks that seating? The pressure to restart can otherwise decide how much comparison you get.
14分Mia, manual loading is covering it; Lin and John, we have retained incoming housings and both pads, so replacement will not remove the items needed for the comparison.
22分Did the replacement pair change the grip, or is that still pending?
20分A supervised check with the specified new pair held the retained housings squarely; we have not compared multiple trays yet, so I am not treating that as the entire cause established.
18分That's a useful observation to retain with the part and pad references. I would make the next tray comparison explicit in the handover so that the first good grip doesn't become an undocumented release decision.
23分And keep the old pads labelled. Ours nearly went in the bin during a tidy-up, which would have left us with a very clean bench and no useful wear comparison.
