Optimization of a Collaborative Robotic Brushing Process for Stainless-Steel Door Frames in an Industry 4.0 Context
Bibliographic record
Abstract
The rise of Industry 4.0 has transformed manufacturing by focusing on automation, precision, and efficiency to meet current industrial needs. This paper discusses automating the stainless-steel door frame brushing, a vital but labor-intensive finishing step through a collaborative effort between Université du Québec à Rimouski and Alstom. A sixaxis Yaskawa collaborative robot was employed to automate this process, using modular programming to ensure consistent quality and full in-factory treatment. Key innovations included (1) geometry-specific subroutines for flat surfaces, corners, and fillets programmed via the Smart Pendant, (2) optimized tool trajectories with approach angles under 30°, and multi-pass brushing to minimize abrasive wear, and (3) a custom positioning jig to improve repeatability. Results showed efficient processing times (5.5 minutes per corner; 25-30 minutes per frame), confirming the viability of robotic brushing for industrial use. The study also highlights the potential of RoboDK software for further process improvements.

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.
