Lumber production has grown from the old axe and two-person saw process to a sophisticated operation involving specialized machinery, such as multiple band saws or laser-beam cutters with digital control, and even optimization techniques to increase the yield of useful material from the log. To the engineer or wood scientist who wishes to specialize in it, wood production presents many interesting technical challenges. The structural designer, however, needs to know little about lumber production, except as it might affect either selection of material or the performance of that material in the completed structure.
