Unlocking Dual Utility: 1D-CNN for Milling Tool Health Assessment and Experimental Optimization
Bibliographic record
Abstract
In a novel application of 1D Convolutional Neural Networks (1D-CNN), this study pioneers a tri-class classification framework for accurately forecasting the Remaining Useful Life (RUL) of milling tools. By harnessing the 1D-CNN’s innate capability to analyze raw time-series data, we eliminate the traditional bottleneck of extensive feature engineering. Our model undergoes rigorous validation using a leave-one-out cross-validation method, catering to the constraints of a limited dataset. When optimized, the model delivers compelling performance metrics: average accuracy, precision, and recall scores stand at 0.90 ± 0.02, 0.85 ± 0.12, and 0.87 ± 0.08, respectively. What sets this work apart is its dual utility: not only does it excel in tool health assessment, but its output also serves as a diagnostic tool for experimental setups. For instance, anomalies detected in the model’s predictions can act as early warnings for potential sensor malfunctions. Additionally, the model’s performance metrics offer invaluable guidance in optimizing experimental parameters, such as choosing the most efficient sampling rate. In summary, this study not only establishes the robustness of 1D-CNNs in assessing milling tool health but also unveils their untapped potential as diagnostic aids for fine-tuning experimental setups.

How this classification was reachedexpand
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.
