Title: A CT-based Simulator for Hardwood Log Veneering

Description: Profits for hardwood veneer manufacturers are dependent on proper initial log breakdown (flitching) decisions. While human skill is often adequate to ãreadä bark indicators of internal defects, it is much more difficult to envision potential veneer patterns that result from different flitching options. Different veneer patterns greatly affect potential markets and veneer value. To help veneer mill operators ãseeä different veneer patterns, we have created a simulator that displays the veneer that results from different flitching and different veneer slicing operations. The simulator uses CT images of a log to construct veneer images. Presently, the simulator incorporates six different types of veneer slicing operations: rotary cut, half-round slicing, quarter-round slicing, rift cut, flat slicing, and back cut. The user can select any of these veneering operations and can then graphically place flitching lines on the log and can view corresponding veneer slices. While CT imaging of logs is not currently part of industrial operations, we feel that this sector of hardwood processing has the highest payback for CT scanning expense and, hence, we view this simulator as a demonstration system that can illustrate potential benefits to manufacturers.
