A comprehensive analysis of cutting forces during routing of multilayer carbon fiber-reinforced polymer laminates
Bibliographic record
Abstract
Analyzing cutting forces during detouring of carbon fiber-reinforced polymer laminates at high cutting speeds is problematic as the recorded signal can be distorted due to resonance of the measuring system. In addition, excessive tool wear can render signal interpretation difficult. In the present study, a fully controlled experimental protocol is used to investigate the instantaneous cutting forces when milling carbon fiber-reinforced polymer laminates in a bid to avoid signal distortion and limit the tool wear effect. A polycrystalline diamond tool was selected for the experiments in order to limit the effect of tool wear on the recorded signals. The fiber orientation influences principally the cutting force amplitude, which varies nonlinearly with the feed. Based on this experimental data, a high-order mechanistic force model in terms of feed per tooth was proposed to predict the cutting forces. The tooth-to-tooth run-out was measured and included in the model, and the model was validated for different feeds, speeds, and number of plies. A good consistency between simulated and measured forces was observed. For the proposed model, the estimation error was approximately ±12.5%.

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.
