Abstract

Research on several hundred well-manufactured 1 and 2A Common red oak boards shows that better edging and/or trimming or division-based remanufacturing can produce boards of higher grade and value. Division-based remanufacturing divides a board into as many as four smaller boards. The UGRS computer program (3,4) grades digitized boards, examines their remanufacturing potential, remanufactures to the highest valued solutions greater than the original board values, and displays the size, defect location, and grade of new boards for UGRS analysis. An example analysis of the effects of such remanufacturing for a simple, gang-rip-first, rough-mill cutting bill is included. Whether boards can be remanufactured profitably depends on the relative prices among the lumber grades and the costs assigned to remanufacturing. All software used in this research is available free of charge.
