Abstract
Across North America the amount of tensioning used in bandsaws varies drastically. Sawblades tensioned to fit circle gauges from 28 feet to 80 feet in diameter are in regular use and performing very well. This raises the questions as to what is the right amount of tension and what effect does it have on cutting accuracy. In this study, the cutting accuracy of five sawblades, with varying levels of tension, have been measured and compared. The results show that little change occurs in cutting accuracy once enough tension has been put into the blade for it to fit an 80-ft circle gauge.

Abstract
Optimization programs, full-profile scanning, and powerful computers used with auto-rotation systems make thorough log rotation, log positioning and sawing decisions possible. However, high log throughput, bumpy log surfaces, and heavy sawlogs make accurate mechanical execution difficult. How accurately can auto-rotation systems execute thorough log rotation and log positioning decisions? Two mill tests were carried out to estimate rotation errors and unintentional log movement. OPTITEK®, Forintek's log breakdown simulator, was used to analyse the effect positioning errors have on the economic benefits of auto-rotation systems.

Abstract
L'industrie du sciage est une composante majeure de l'économie canadienne. Avec les coûts croissants d'approvisionnement et la qualité décroissante de la matière première, cette industrie doit améliorer son procédé actuel ou chercher de nouvelles façons de récupérer davantage de chaque arbre. Étant donné que les opérations effectuées lors du procédé de sciage impliquent des décisions comportant plusieurs paramètres, l'utilisation de l'ordinateur s'avère de plus en plus avantageux. Dans le cadre de ce projet, des modèles ont été développés afin de simuler le sciage selon la courbure. Cette technique, de plus en plus répandue, permet de récupérer davantage de sciages de meilleure qualité. Avec la panoplie d'équipement de sciage courbe ayant chacun ses particularités, il devient difficile de savoir quelle technologie sera la mieux adaptée à nos besoins. L'utilisation de la simulation permettra de mieux comprendre cette technologie et de bénéficier de son plein potentiel.
