Effects of preprocessing 1 Common and 2A Common red oak lumber on gang-rip-first rough-mill dimension part yields

Using the ROMI-RIP simulator we examined the implications of preprocessing for gang-rip-first rough mills. Rip-first rough mills can improve yield and throughput by preprocessing 1 Common and 2A Common hardwood lumber This ca n be achieved by using a chopsaw to separate poorer quality board segments from better ones and remove waste areas with little or no yield. This prepr ocessing is in addition to major production benefits from crosscutting out crook or sidebend.
