Abstract
An experimental study is reported on the grinding of a titanium metal matrix composite (TiMMC) using electroplated diamond wheels. Flat surface grinding experiments were performed at a fixed wheel speed vs = 20 m/s, various depths of cut a = 0.03-0.08 mm, and workspeeds vw = 10-100 mm/s. Additional tests were also conducted on titanium alloy (Ti alloy) for comparisons. The wheel wear and its effects on grinding forces, power, surface roughness, and workpiece microstructures are presented. The process limits were also investigated. It was revealed that steady state wheel wear on TiMMC was slightly slower than on Ti alloy. Low specific energy ranging from 16-34 J/mm3 was obtained for both materials. It was found that surface roughness decreases for TiMMC, but increases for Ti alloy, with increasing workspeeds. Plastic deformation leads to microstructural changes in the form of twinning below ground surfaces.

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 it
