A Coordinate Measuring Machine with Auto-Learning Capability
Bibliographic record
Abstract
Coordinate Measuring Machines (CMMs) are widely used by auto-industry to measure the geometrical features of auto parts. For a CMM to accurately measure the geometrical features of a part, a model has to be developed and added to the CMM library. This process is time-consuming and may take several weeks to be completed. Moreover, vibration as an environmental factor can potentially distort sampled data and reduce measurement accuracy. This paper presents an auto-learning algorithm to reduce the time required to add a new part to a CMM library. Moreover, a cost-effective solution to reduce the effects of vibration on measurement results is presented. An improved Modified Multi-Class Support Vector Machines (iMMC-SVM) algorithm is developed to determine the geometrical features of parts through comparison with a reference part using a laser-based CMM. Experimental measurements are conducted using a prototype CMM design by the research team to validate the proposed solution. The results indicate that the proposed method reduces vibration noise by 6.18%. Such a noise reduction significantly improves the overall measurement precision.

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.
