What the drawing demands
Vacuum and UHV parts such as chambers, flanges and showerheads demand extremely low outgassing and flatness within a few microns, often only reachable with grinding or lapping on top of milling. Critical hole patterns, such as showerhead holes and bolt circles on vacuum flanges, sit on tight GD&T position tolerance and are checked by CMM, because a leak-free seal depends on it.
What the model learns here
In this sector the model is learning to connect which face carries a seal, which hole pattern inherits a position tolerance, and which surface carries an outgassing requirement to the part's geometry. Blake proposes these links for review, traceable to the inputs they came from. The cycle time that follows remains a direction until a connected pilot shop confirms it.
What the model learns here keeps a seal from failing.
Who this matters to
Reads the outgassing, flatness and position-tolerance notes that drive the quote, and confirms or corrects what Blake proposes.
Plans the grinding or lapping pass a tight flatness callout forces on top of milling, and the CMM check a sealing surface needs.
Carries the pricing risk when a tolerance chain is misread: a leak-free seal is the difference between a good quote and a warranty claim.
Where this model can help
Linking GD&T positions
A position tolerance in a chain is proposed as linked to the face or hole it controls, so a sealing surface keeps its reference, for the estimator to confirm.
Tracing outgassing requirements
Surface finish and outgassing notes are shown with the same traceability as any other requirement: measured, derived, assumed or unconfirmed.
CMM report as a future outcome, direction
A CMM report is exactly the kind of measured outcome the model is designed to learn from, once a shop connects its inspection data. Not yet confirmed running.
Vacuum parts as a feature family, direction
Chambers, flanges and showerheads share a family of features the model is designed to recognise across drawings. A design principle, not a confirmed, ratified function.
