Implementing Advanced Technologies in the Sand Casting Supply Chain
Bibliographic record
Abstract
How many castings should be poured before getting a useable part? The ideal answer may be one, but the reality is that the ideal is infrequently realized. What alloy is the part? What is its size? What is the complexity? How is the part complex: many interior cores, many thick to thin section transitions, very thin walls, or something else entirely? No two part geometries will be exactly the same, so the challenges and expectations for each part will be different. At Sikorsky, our sand cast components only seem to be getting more complex, with more demanding dimensional and metallurgical requirements. All of these factors makes the casting of these parts more challenging. This also coincides with a time where lead times and costs to develop a new casting are being scrutinized.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
