Yield Deviations in Hardwood Dimension Stock Cutting Bills

Yield charts developed by the U.S. Forest Service provide furniture and dimension manufacturers with dimension stock yield estimates. In this study, actual cutting bill yields, sampled from three dimension manufacturers, were found to deviate from these chart estimates. Results showed that yield deviations from No. 1 Common were inversely proportional to the range of cutting lengths. Regression equations were developed which explained 47 percent of yield deviations. We believe that the cutting bill flow or arrangement of parts influenced operator efficiency and thereby indirectly affect the yields obtained.
