Which outline overlaps? The open fingers, the closed gripper, or some rectangle somebody drew round both? You need that distinction before moving the whole arm. A sketchy tool envelope can kill a decent layout or approve a bad one.
18 pointsIt's the rectangle around both finger positions. The gripper body is drawn separately, and that seems clear in this view
11 pointsThen you haven't shown a collision yet. You have shown a space that needs checking. Does the tool need to open there, or is that after it has moved further into the machine?
17 pointsI don't know where it opens yet. The sequence sheet just says load, release, retract. No intermediate positions
7 pointsThat's the missing bit. Ask for the release pose and the first withdrawal move with the actual finger geometry. Nobody can answer from 'retract'.
4 pointsCannot choose the mounting position from one view. Add a section through the doorway, with the tool at release height.
13 pointsAnd include the wrist in that section. We've spent all this time discussing fingers while the part behind them is apparently invisible.
13 pointsOur loading position cleared beautifully. The trouble was reaching a dropped part afterwards, because the new base blocked the access door. Get whoever clears stoppages to look at this drawing too.
10 pointsI asked our setter. He needs the front opening for fixture changes, so a base straight in front would create another problem
19 pointsGive the designer that fixture-change requirement now, with the trolley space marked, or you'll get a lovely robot drawing that quietly borrows the setter's entire working area.
19 pointsHas anyone put the actual door travel on the plan? A rectangle labelled 'door' isn't its swept space. Sorry to labour it, but that detail matters here.
5 pointsYes, the machine supplier's section shows its full travel. Thanks for the wrist point earlier; our designer hadn't included the rear of the tool adapter
15 pointsUseful catch. Now check the same assembly on the way out with a part held. The incoming empty tool and outgoing loaded tool don't occupy identical space.
18 pointsWho gets the final drawings after installation? Ours stayed in somebody's email and night shift kept using the first print. Put a revision on the copy by the machine.
21 pointsMaintenance will own the layout copy. We already have a drawing folder for this mill, so I'll ask for the approved version there
15 pointsGood home for it. Include tool revision as well; fingers change without anyone thinking the layout changed.
10 pointsThe updated section shows clearance for release, but the loaded withdrawal still needs work. I'm leaving the base choice open until that's drawn
18 pointsFair result. When that path arrives, check its intermediate poses too. Two clear endpoints can still have something expensive between them.
