The Influence of Log Offset on Sawn Timber Volume Yield

Abstract

Accuracy of aligning and positioning of log and cant during sawing in relation to blades in the sawing machine depends on equipment was used, shape and dimensions of the log or cant and human factor (if it is manual). Theoretically optimal positioning presupposes maximization of the volume yield but considerable impact was observed on value yield as well. For straight logs main positioning faults are caused due to log parallel and angle dislocation known also as offset and skew. Positioning faults affects location, type and values of wood features and sawn timber qualities forcing thus sawmill-men in Lithuania pay more and more attention and investments. The influence of offset on different production aspects was tested in the real typical sawmill as well as using elaborated by us special sawmill model.
