Study of the Milling Process for Thin Components Using a Flexible Setup Configuration
Bibliographic record
Abstract
In the aerospace industry, numerous large parts with complex curvatures and several thin wall/web pockets are required to ensure stiffness and low weight for aircraft structures. Costly processes and dedicated setups are usually required to machine such thin plate components. Therefore, investigating new machining methods involving flexible setups for such parts is an interesting avenue for cost savings, but a big challenge as well, due to a lack of support and part flexibility. In fact, a flexible setup is a tooling system with several adjustable positioning supports, which can easily adapt to different workpiece geometries. In this paper, an experimental investigation of the machining of pockets for thin components using flexible setup is presented. A design of experiments is proposed to verify the ability of pocket machining for thin plates of aluminum 2024-T3 in terms of quality. During the machining tests, the cutting forces were measured using a Kistler dynamometer table, while the displacement of the plates, for the flexible setup configuration, was measured using a Keyence displacement sensor. The force and displacement signals were analyzed and a fine correlation proposed between them and the resulting quality of the part, expressed in terms of profile and size errors.

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.
