Does Gang Ripping Hold the Potential for Higher Clear Cutting Yields.
Abstract
Cutting yields from gang ripping hardwood lumber graded by the National Hardwood Lumber Association standard grades are determined using the technique of mathematical modeling. The lumber used is the same as that in an earlier mathematically modeled determination of cutting yields from traditional rough mill procedures. Mechanical cutting factors such as kerf, cutting lengths, and minimum salvage size are also the same in both studies. A comparison of yields between the two systems is made. While gang ripping produces higher total yields in all grades, the gain tends to be in the medium and shorter cutting lengths. (Author)
