Precision Cutting of Thin Plate of Copper by Single Mode Fiber Laser with Newly Designed Nozzle(Laser processing)
Bibliographic record
Abstract
The fundamental characteristics of laser cutting for thin copper plate by a Q-switched single-mode fiber laser were experimentally investigated, and the effects of the nozzle shape on cutting results were also discussed. High speed cutting of 29mm/s could be carried out with a newly designed nozzle, since high assist gas pressure could be supplied on the workpiece without MSD. Nozzle Laval 800 makes it possible to cut more efficient, since the melted material in the kerf decreases compared to a traditional convergent nozzle. Using a Q-switched single-mode fiber laser, the kerf is very fine, and color change around the kerf is hardly observed by oxidation due to little heat conduction from dross. Therefore, it proved to be available in cutting of thin metal plate.

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.
