A simple technique to characterize the role of work hardness in hard part machining
Bibliographic record
Abstract
An experimental technique that employs a Jominy end quench test specimen for rapid characterization of the machining response of a steel with reference to its bulk hardness is presented. Employed widely by metallurgists to appraise the hardenability of a steel, the Jominy test entails the quenching of a standard cylindrical specimen from one end, on having heated it to the austenitizing temperature. The cooling rate at any transverse section of the specimen is therefore dependent on the distance of the section from the quenched end, which brings about a continuous variation of material hardness along its length. The use of such a specimen as the workpiece to investigate the machining response of the steel with respect to its hardness significantly reduces the time, effort and cost involved in reliably optimizing a hard part machining application. Cutting force and surface finish data are presented to demonstrate this simple, innovative concept.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
