Traditional Product Recovery
Studies: The Ecologically Sustainable
Objective: Evaluate the use of AUTOSAW to simulate sawing of softwood lumber in the Pacific Northwest.
What is AUTOSAW? An interactive sawing simulator developed by New Zealand Forest Research Institute. AUTOSAW simulates the sawing of logs into lumber. It edges and trims the lumber then assigns grades using WWPA rules for dimension and appearance lumber. AUTOSAWs lumber grading is based on its ability to locate branches within logs and to carry knot locations onto sawn lumber.
lumber grade results from AUTOSAW have not beenvalidated so it
is not possible to estimate the accuracy of its volume recovery
or grade yield projections. In this study, a sample of 48 Douglas-fir
trees were sawn into about 1100 pieces of dimension lumber (12
MBF) using a Wood Mizerä portable
sawmill. Sawing of the logs from these trees will be simulated
using AUTOSAW. If validation is successful, we will have the capability
to simulate production of many different wood products from the
