Abstract

fetched live from OpenAlex

This research pertains to the initial steps in designing an end-effector for automated polishing, and focuses on: (1) controlling the contact stress on the work-piece surface, and (2) controlling the torque or the spindle speed to overcome the friction torque (hence, preventing the tool from stalling) and maintain a desired polishing rate. By forming a contact stress model, parameter planning is achieved and then augmented to already existing tool path data. A dynamic model for the particular end-of-arm tooling used is derived. The dynamic model clearly shows a coupling effect between the pressure and spindle speed of the system. A closed-loop control scheme, designed to eliminate the coupling is then introduced. The effectiveness of parameter planning is assessed through open loop testing. The parameter planning method allows polishing without significantly changing the part profile, whereas, without the parameter planning, the part profile is changed considerably.

Full frame distilled prediction

Teacher imitation

Not 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.
