references The Automated Lumber Processing System (ALPS) is a multi-disciplinary continuing effort directed toward increasing the yield obtained from hardwood lumber boards during their process of remanufacture into secondary products (furniture, etc.). ALPS proposes a nondestructive vision system to scan a board for its dimension and the location and expanse of surface defects on it. This information is then used to determine an efficient placement of the desired wood parts. Finally, a laser path planning algorithm is used to obtain an efficient path for the Computer Numeric Controlled (CNC) laser to follow to effectively punch out desired parts. While some individual subsystems of ALPS have been reported separately in previous communications, our recent success with the vision system required by ALPS has made the integration of the individual modules of ALPS possible. The vision subsystem and some other subsystems have been prototyped at West Virginia University. Recent efforts have been directed toward integrating these subsystems with the material-handling and laser cut-up system at Michigan State University in an attempt to create a fully functional prototype of ALPS
