An Accurate and Efficient Approach to Undeformed Chip Geometry in Face-Hobbing and Its Application in Cutting Force Prediction
Bibliographic record
Abstract
Due to complexities of face-hobbing of bevel gears, such as the intricate geometry of the cutting system, multi-axis machine tool kinematic chains, and the variant cutting velocity along the cutting edge, deriving the instantaneous undeformed chip geometry, as one of the most important characteristic of material removal, is a challenging process. In the present research, all these complexities have been taken into consideration to obtain an in-process model and undeformed chip geometry, and predict cutting forces. The instantaneous undeformed chip geometry is obtained using the derived in-process model. As an application of the proposed methods, cutting forces are predicted during face-hobbing by oblique cutting theory using the derived undeformed chip geometry and converting face-hobbing into oblique cutting. The proposed methods are applied on two case studies of face-hobbing of bevel gears and the chip geometry is derived and the cutting forces are predicted.

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.
