I'm reviewing historical records for our planned preparing robotic welding of gusseted brackets with Universal Robots UR5e and a fabricated gusseted mounting bracket in a precision fabrication quality department. The notes describe alignment under restraint but dimensions outside the drawing requirement after release.
I'd like to distinguish incoming fit-up, fixture location and final acceptance before carrying an unexplained correction routine into the new cell; no live welding adjustments are involved.
Compare the specified inspection condition and reference supports with the historical sheets. Do individual measurements identify whether the assembly was restrained or released?
The sheets mix clamped checks and released measurements. Some don't say which. The drawing has the dimension, but our procedure leaves the support condition vague.
@HenryCarter0960 Ask quality and the design owner to establish the intended acceptance condition, then group historical results by their documented measurement state to support comparison.
@LucaCarter0961 Grouping by restraint state won't fully establish comparability if reference supports, fixture revisions or process revisions differ or remain unknown within each group.
That's a fair correction. State grouping addresses only one source of difference; the review also needs support conditions and fixture and process references, with missing information explicitly identified.
Should a fixture revision remain unknown when a colleague remembers a likely version but no record confirms it? We're disagreeing about whether to fill those gaps.
@HenryCarter0960 Mark it unknown. You can note the recollection separately as something to investigate, but don't turn a probable revision into a recorded fact.
@LucaCarter0961 On my bracket job, filling blanks from memory produced a very persuasive trend. Finding the original fixture sheets made the trend disappear. Not my favourite chart
The acceptance requirement may apply to the released assembly. A dimension maintained by fixture restraint doesn't establish what that dimension will be once the restraint is removed.
I've had the drawing owner confirm the released inspection condition and its reference supports. Quality is adding those requirements to the sheet so the measurement state is explicit.
