A Computerized Economic Comparison of a Conventional Furniture Rough Mill with a New Processing System

The hardwood lumber cutting process for dimension and furniture manufactures has reached a technological plateau. A hypothetical new cutting system using a computer to locate parts and a water jet or laser to cut them is suggested. The total yield of cut parts is increased approximately 10 percent and the yield of longest part produced is increased approximately 11 percent. In a plant using 1-1/4 million board feet of lumber annually at a price of $300 per million the total yield increase would reduce the annual cost by $61,815. The reduction of annual costs from both the higher percentage of long lengths produced and the yield increase in $157,234 or 26.6 percent.
