Experimental study of the effect of tool orientation on surface quality in five-axis micro-milling of brass using ball-end mills
Bibliographic record
Abstract
The effect of tool orientation on the final surface geometry and quality in five-axis micro-milling of brass using ball-end mills is investigated. Straight grooves are cut with different tool inclination and tilt angles, and the resulting surfaces are characterized using an optical profilometer and microscope. Results of various cutting experiments and analysis of the final surface geometry show that varying the tool orientation reduces rubbing of the material at the bottom of the grooves, which often occurs in ball-end milling of brass. Results also indicate that a non-zero tool inclination angle can result in more accurate geometry profiles compared to the case where the tool axis is normal to the surface. The experimental analysis for surface roughness profiles also shows that applying a tool inclination angle of 15° can considerably improve the surface roughness at the bottom of the grooves.

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.
