Abstract
This work investigates the effectiveness of using vibration data to jointly monitor tool wear during machining processes using the Fast Fourier Transform (FFT) and Empirical Mode Decomposition (EMD).A range of instruments and operational settings are examined in order to thoroughly evaluate these methods.Relevant intrinsic modes are found by statistical analysis involving Kurtosis, Skewness, and RMS; IMF 4 is found to be the best mode for tracking tool wear.The efficacy of EMD in tool wear monitoring is further supported by FFT analysis, which validates the veracity of EMD results.It is imperative to exercise caution when interpreting the results, as additional study and validation may be required.However, our work highlights the potential of FFT and EMD techniques for realworld use in precise and trustworthy tool wear evaluation during milling processes.

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
