Project: New Forest Industry Production Systems Based on High-speed CT Scanning overview

X-ray computed tomography (CT) is a well-known research tool in the field of wood science, but has always been too slow and not robust enough for use in an industrial environment. Within this project, a high-speed CT scanner has been developed; capable of reaching around 10 times higher speeds than any other industrial CT scanner. Image analysis algorithms have also been developed, capable of automatically extracting a large number of relevant parameters from the CT images of the logs. This is the first scanner of its kind, meaning that the project has opened up completely new possibilities of optimizing the log breakdown. Different production strategies have been evaluated, and it has been found that by optimizing the sawing position with respect to internal features of the log, there is a potential to increase the value of sawn goods by 10%–20%. With current positioning equipment, it is probably possible to utilize around half of this potential. This means that an important side-effect of the project is that manufacturers of sawmill equipment will be urged to produce machinery capable of positioning the logs much more accurately than today.
