Two tooling offers for our FR5 housing transfer both quote the workpiece mass as their load check. I've drawn long fingers to reach into the assembly nest, plus an adapter and hose fittings. None appears in their figures.
I know those bits aren't weightless, despite procurement's hopes. What should the revised load review include?
Complete held assembly. Tool, adapter, fittings and part. Mass, centre of gravity and relevant inertia data, checked against the manufacturer's applicable load guidance.
Thanks. One offer has a tool mass hidden in the drawing notes but still calls the part-only figure 'total payload'. I'll ask them to reconcile that before comparing the offers.
Ask who updates the assessment when those fingers change. Extended fingers tend to acquire another small extension when the first awkward variant arrives. The person replacing them needs to know that the approved configuration has a boundary.
I've sent the loaded and empty assemblies with revision numbers. The housing is offset sideways as well as forward, which neither summary showed. Asked both suppliers for their complete assessment and assumptions, not another capacity sentence.
Request an explained result you can hand to maintenance. I can't say whether your arrangement is suitable, but a signed-off tool revision with traceable assumptions is much more useful than 'part weighs less than payload'.
