Effect of Planing on Physical and Mechanical Properties of Sugar Maple Wood
Bibliographic record
Abstract
Matched specimens of sugar maple wood were prepared using two types of planing machines, a conventional planer, and a fixed-knife pressure-bar planer. The equilibrium moisture content (EMC), swelling in all principal directions, and the compliance coefficient in radial compression were measured after adsorption and desorption experiments. Two specimen sizes were used for these experiments. The results showed that conventional planing affected the superficial layer, and a significant negative effect on the EMC and swelling behavior of sugar maple after a cycle of moisture adsorption-desorption existed. No differences were found between planing methods for the radial compliance coefficient. These findings are in agreement with earlier results showing a negative effect of conventional planers on the superficial layer of wood. We confirmed that less affected properties could be obtained using the fixed-knife pressure-bar method. Finally, the EMC and the radial compliance coefficient, but not the swelling, were slightly affected by the specimen size.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
