Orthogonal Experiment on the Surface Quality of Carbon Fiber Reinforced Plastic Cut by Abrasive Water Jet
Bibliographic record
Abstract
The abrasive water jet (AWJ) is an immensely popular tool to machine hard-to-cut materials. Taking the surface roughness as the metric of cutting quality, this paper designs and implements an orthogonal experiment for the AWJ cutting of carbon fiber reinforced plastic (CFRP), a lightweight composite widely adopted for high-precision applications. Four factors that affect cutting quality, namely, target distance, pump pressure, nozzle traversal speed, and abradant flow rate, were selected, and divided into five levels for the orthogonal design. Since different factors differ in the value on the same level, the orthogonal design was improved by the quasi-level method. The results of the orthogonal experiment show that the nozzle traversal speed exerted the greatest effect on cutting quality, followed in turn by pump pressure, abradant flow rate, and target distance; the optimal cutting quality could be achieved at the target distance of 7mm, the abradant flow rate of 5g/s, the pump pressure of 340MPa, and the nozzle traversal speed of 200mm/min. The research results provide experimental evidence for high-quality AWJ cutting of the CFRP.

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.
