Automated laser fabrication of high performance saw blades
Bibliographic record
Abstract
Automated Laser Fabrication (ALFa) is an emerging computer-aided manufacturing technology that uses a laser beam to melt and deposit the injected powder to fabricate near net shape 3-D components and add delicate features onto the existing components with short turn around time in a layer-by-layer fashion by metal deposition. Recently, we have extended our efforts to deposit WC on High speed steel substrate to fabricate high performance saw blades. This paper reports the fabrication and characteristics of High performance saw blades using ALFa by depositing WC-Co on High speed steel. The laser fabricated samples were subjected to various mechanical and metallurgical analyses. The results showed that fully dense and crack free deposition of WC-Co with an excellent metallurgical bonding and low dilution. No melting of WC particles in the Co matrix has been observed during the microscopy. The average microhardness at the tool surface was in the range of 1450 - 1850 HV, while that at blade was 700-850 HV.

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.
