One of the difficulties in solid log modelling is working with huge data sets, such as those that come from computed axial tomographic imaging. Algorithmic procedures are described in this paper that have successfully reduced data without sacrificing modelling integrity.
Knowledge organisation plays an important role in building a knowledge-based product design blackboard system. Well-organised knowledge sources will facilitate the effectiveness and efficiency of communication and data exchange in a blackboard system. In a previous investigation, an approach for constructing blackboard systems for product design using a… (More)
This paper describes work in progress concerning the development of an integrated approach to hardwood processing. The motivation for this work, research direction, and research developments are presented.
The planning of how hardwood logs can be sawn to improve recovery of high-value lumber has always been hampered by the limited information provided by external defects, and whatever internal defects are eventually revealed on the cut log faces by the sawing pattern. With expanded markets, lower-quality logs, increased competition from non-wood products,… (More)
In present-day hardwood sawmills, log breakdown is hampered by incomplete information about log geometry and internal features. When internal log scanning becomes operational, it will remove this roadblock and provide a complete view of each log's interior. It is not currently obvious, however, how dramatically this increased level of information will… (More)
A versatile microcomputer-based interactive graphics sawing program has been developed as a tool for modeling various hardwood processes, from bucking and topping to log sawing, lumber edging, secondary processing, and even veneering. The microcomputer platform makes the tool affordable and accessible. A solid modeling basis provides the tool with a sound… (More)
