Influence of Cutting Conditions on the Wear Resistance of Tools with a TiB2 Coating during Titanium Alloy Machining
Bibliographic record
Abstract
The effect of cutting conditions on the tribotechnical characteristics and wear resistance of cutting tools with and without TiB2 coating during processing of a TiAl6V4 alloyed titanium alloy has been investigated. It was found that when processing TiAl6V4 alloy, the efficiency of a TiB2 coating on carbide cutting tools significantly depends on the cutting conditions. Wear estimates in combination with XPS and SEM studies of worn surfaces show that TiB2 coated tools are most efficiently used for rough turning at low cutting speeds (45 m/min) and a large depth of cut (2 mm) under conditions of intense build-up. It is assumed that this is due to the formation of thermal barrier films of TiC, as well as a large amount of tribooxide B2O3, which serves as a liquid lubricant. During finishing (the finishing operation) at higher cutting speeds (80 and 150 m/min), when crater wear on the front surface of the cutter prevails, the wear resistance of the coated and uncoated tools is practically the same. This indicates that there is no one-size-fits-all solution for different machining conditions of alloyed titanium alloy when different wear mechanisms dominate.

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.
