Abstract
The presented work proposes a numerical 3D finite element model that is able to predict cutting forces, in hard milling of AISI 4340 steel. The numerical 3D finite element model was developed using ABAQUS/Explicit 2020 software and is based on the Lagrangian approach. Johnson-Cook strength and fracture models were adopted, to simulate the elastoplastic with isotropic hardening behavior of the workpiece material. Material's flow stress was defined in terms of strain, strain rate, and temperature. Machining tests were also carried out to verify the proposed numerical model. The close agreement between the simulated cutting forces and those that were obtained experimentally from machining tests verified the accuracy of the proposed numerical model. Chips were also collected during the machining tests and were compared to the numerically simulated ones to add another layer of validity check to the proposed numerical model.

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 it
