    This paper reports ongoing work on a series of computer programs developed to automate hardwood lumber processing in a furniture roughmill. The program computes the placement of cuttings on lumber, based on a description of each board in terms of shape and defect location, and a cutting bill. These results are suitable for use with a high-power laser to cut the parts from the lumber. The placement algorithm employed is based on a heuristic approach that provides simplicity and short computation time. In its present form, the program is intended to be used as a research tool for further investigation of an Automated Lumber Processing System (10) that, in addition, incorporates computer vision to grade and locate defects in lumber.
