Industry-Education Integration Case for AI+ Practical Teaching: Machine Tool Vibration Signal Recognition
Bibliographic record
Abstract
With the continuous and rapid development of artificial intelligence (AI) technologies, educators are increasingly faced with the pressing challenge of how to effectively incorporate AI into professional instruction. Using the course "Mechanical Testing Technology" as an example, this study investigates how AI techniques can be applied to analyze vibration signals from machine tools, adopting an approach that integrates academic instruction with industry practices. Vibration signals often display nonlinear and time-dependent behaviors due to multiple variables such as tool degradation, workpiece material differences, and variations in cutting conditions. In such intricate environments, artificial intelligence shows considerable promise. This study emphasizes key processes including the real-time collection, filtering, and noise reduction of vibration data, along with the evaluation of machine tool vibration conditions using both time-domain and frequency-domain analytical methods. It not only confirms the effectiveness of AI-based approaches in recognizing vibration patterns in machine tools but also provides valuable insights and practical references for future research and applications in this area.

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.
