The moulding and millwork industries process nearly 1.3 billion board feet of Ponderosa Pien annually. Unfortunately, thousands of trees are harvested unnecessarily to compensate for inefficient processing. To help improve this situation, researchers at the Forest Products Laboratory developed maximum cutting yields for 64 Shop lumber in grades No. 1 Shop, No. 2 Shop, and No. 3 Shop. Yields lumber data base and simulating sawing of the lumber by the computer program OPTYLD. Results may be used to compare cutting yields between 64 Shop grades, to guide grade selection, and to estimate possible improvements in processing decisions. Results also encourage more automation in lumber processing. This paper is part of a series on maximizing cutting yields of 54 and 64 Shop, and 64 Vertical Grain lumber. The Timber Quality Research Project of the USDA Forest Service Pacific Northwest Forest and Range Experiment Station, Portland, Oreg., made a significant contribution to the completion of this study through their assistance and expertise.
