Our mill fixture-exchange sketch shows the FR5 reaching a short steel blank, but no gripper body and no open door. I can see why the point is reachable. I can't see how we get the actual kit in and out. Who should combine those missing bits?
The integrator should coordinate the actual machine survey and complete tool model with the machine owner and toolmaker. Ask for entry and exit with the blank held as intended, plus empty withdrawal where relevant. Catalogue outlines can start the discussion, but they won't account for your particular door fittings.
