Rough mill policies and practices examined by a multiple-criteria goal program called ROMGOP
A rough mill linear programming formulation called OPTIGRAMI (OPTImum GRade MIx) generates an optimal least cost solution. However, it cannot easily reconcile multiple-conflicting, incommensurate goals. In general, a major weakness […]

Saving Lumber Through Blanking with the Two-Way Thicknessing Planer
Blanking or the pre-planing of lumber before it is finish-planed, is done by a special planer which thicknesses boards twice–first from the back, then the face. The machine is described […]

Saw Blade Tooth Wear Reduction By Electrically Insulating the Saw Blade
It has been demonstrated in past works that when machining green (wet) wood, electrochemical reactions occur between the cutting tool and the liquid component of the wood. This reaction is […]

Saw Kerf Width Versus Sawtooth Width
Eighteen center cants from oak, cherry, and Maple logs were sawn into 4/4 lumber. The cants and resulting lumber were measured at three points. The difference-between the sum of the […]
