Abstract
Prediction of cutting forces is one of the fundamental stages in the modeling of machining processes. The costly machining tests can be replaced by virtual simulations where cutting parameters and material properties can be altered repeatedly with no cost. Broaching is one of the machining operations which is extensively used in the industry. The geometry of broaching tool varies according to the desired profile of the workpiece which can be a simple line or complicated curves. This broad range of geometries imposes complexity on the distribution of the chip load along the cutting edge. Therefore, introducing a practical force model for broaching operation can be challenging. An attempt is made in this paper to present a force model for broaching. The newly proposed force model expresses the cutting edge as a B-spline parametric curve and uses its flexibility to calculate the chip load as well as cutting forces for orthogonal and oblique broaching. Verified by previously published experimental results, the presented model has a great capability to simulate broaching cutter geometry along with cutting forces.

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
