A Normative Analysis of a System-6 Mill

A computer simulation of the cutting process of a System-6 mill was developed for exploring the yield potential under various system parameter specifications. For this study, 382 red oak 6-foot boards, in 4 grades, 2 board widths, and 4 quality classifications were processed by the simulation program using 2 different sets of system parameter specifications. A four way analysis of variance of cutting yields showed significant differences in mean yields for grades, widths, and quality classfications, but failed to show any differences for the two sets of system parameters. A contingency table analysis of cutting lengths produced showed that choice of system parameters can have an effect on the distribution of cutting lengths. A similar analysis of cutting widths produced showed no statistical differences due to changes in system parameters.
