Résumé: | Veneer checking is a common enough occurrence in woodworking. It appears as cracks in the veneer
and generally following the grain. Their appearance and the variation of their depth and frequencies
have tremendous impact on their utilization. Finding a means of identifying and characterizing the
veneer checks is an important ongoing challenge. An automated device, named SMOF, was
developed in LABOMAP (Arts et Metiers – France) and achieves this task. By using the SMOF
device, the lathe checks occurred in veneers of two species: zeen oak (Quercus canariensis Willd.)
and afares oak (Quercus afares Pomel) were detected, automatically imaged and then, the depth
and intervals of checks measured. The results were described by statistical distributions that
exhibited abnormalities, such as skewness and kurtosis, which were assessed by mode analysis. It
has been established that hot soaking temperature (from 60°C to 90°C) reduce slightly the cutting
forces for both species, no produce significant heart checks within the loose side of veneers.
However, low soaking temperature (from 50°C to 65°C) allow avoiding deeper lathe checking,
producing shallower ones acceptable for veneer production. |
