Our aluminium blank clears the fixture opening on the FR5 layout. Toolmaker added the jaw backs and suddenly it doesn't. Before anyone redraws the entire cell, I want to check whether the problem is the opening itself or the angle they chose to bring the tool through. Door is missing from this view too.
blank fits, jaws don't?

Does the jaw drawing include the blank being held?

Why is the door missing from a clearance argument?

Aaron, yes, blank is in it. Gabriel, old machine drawing. Door got treated as a later detail. I've asked our setter to mark its working opening on the same view.

Do the cheap drawing check, certainly. But do not spend days saving a base position nobody has actually committed to. I walked away from a layout that consumed the changeover route whichever way we turned it.

If there is another approach available, Anil, what makes this one attractive? Shorter travel, or does the setter need the other side? That would change how much effort I would put into it.

Setter works from the other side. I'm trying to keep that access. Isabel, agreed about not falling in love with a dot on the floor. This dot is currently only pencil.

Can the jaw backs be shorter?
8pointsReplying to AaronBrooks0784
That is one for the toolmaker, Aaron. Shortening a drawn outline is very cheap until someone has to make it grip properly.

Meant ask them, not cut them ourselves.

Fair enough. A revised jaw could help, but I would want them to check release as well. A part can be easy to carry in and awkward to leave behind.

Door outline is on the drawing now. Straight entry is blocked by the jaw backs; angled entry gets those past but puts the rear fitting at the door edge. So there are two snags, not one.

Does either approach leave room for the opened jaws?

Imran's release point matters here. Anil, have you been given just the closed-tool picture?
11pointsReplying to IsabelArcher0387
Only closed. Toolmaker sent the open outline after I asked. That also interferes at the angled position. Thanks, Imran, that would have been an expensive omission.

So that angle is out?
16pointsReplying to AaronBrooks0784
With this tool, yes.

Would the setter accept a different fixture orientation, Anil, or would that just move the obstruction into their way? I do not know your machine access well enough to guess.
6pointsReplying to ImranArcher0392
Moving the fixture can also change their loading job. Do not offer it as a painless fix before they have seen it.
16pointsReplying to ImranArcher0392
The setter has looked at the alternative orientation and doesn't want it. Harder to clean the pocket and inspect the seat. We have binned the angled approach and asked the toolmaker whether a different tool concept is worth pursuing.

At least the door finally got a vote.
