Description: Lumber grade effect on hardwood-part processing time was investigated with a digitally described lumber database in conjunction with a crosscut-first rough mill yield optimization simulator. In this study, the digital lumber sample was subdivided into five hardwood lumber grades. Three cutting bills with varying degrees of difficulty were Cut." The three cutting bills and the five grade sorts were input into the rough mill simulator. Ten randomized replications were run for each of the lumber grade/cutting bill combinations. These 10 were used in the statistical analysis. The dependent variable for each replication was the number of cuts required at each saw (crosscut. straight-line rip, and salvage). By counting the number of cuts and not measuring actual operator times, as in other studies, operator variation was eliminated from the experiment The lumber database and the rough mill simulator 'isolated the effect of lumber grade on part processing rates. The analysis indicated that significant differences existed among the lumber grades tested and the number of cuts required to fill the three cutting bills. As expected, the general trend showed that as lumber grade improved, the number of required cuts decreased. This trend was true across the three cutting bills and at each of the saws.
