Abstract
The utilization of robots, for mechanical part assemblies, is a current practice. Existing methods and software permit to simulate tasks and program them off line using the perfect geometry of the parts. However, as the parts to be assembled are never perfect the adjustment time of these programs is often too long. It is indispensable to find models that can integrate these manufacturing uncertainties at the simulation level. The method proposed can replace the verification using manual functional gauges and can be integrated to a simulation software. In relation to the existing methods, it is especially suitable for the intended parts to be assembled and the datum reference frame (DRF) is defined at maximum material condition. This paper proposes a method for all situations of the DRF where the part is in conformance. It can be applied to inspection, as well as to tolerance analysis and synthesis. A kinematic model is used to represent the permissible motion of the DRF.

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
