In flat sawing, the log is passed through the blade cutting off plank after plank without changing the orientation of the blade or log. The resulting planks have different growth ring orientations when viewed from the end. The relative angle that form the rings and the surface go from almost zero degrees in the external planks to almost ninety ...
More optimized machines now cut the smaller diameters since they are far more efficient and can provide greater production. Dependent upon the log diameter, head saws can cut a log at speeds ranging from 1 to 300 feet per minute (0.30 to 91.44 m/min). Generally, log carriage speeds are adjustable for optimal performance.
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the ...
Lumber produced by flat sawing from a log. Plank A has been cut from the middle, and is as wide as the original log. Plank B has been cut closer to the side, and shows slash grain. Flat sawing, flitch sawing or plain sawing is a woodworking process that produces flat-cut or plain-cut boards of lumber. [1]
A plank is timber that is flat, elongated, and rectangular with parallel faces that are higher and longer than wide. [1] Used primarily in carpentry, planks are critical in the construction of ships, houses, bridges, and many other structures. [2] Planks also serve as supports to form shelves and tables. Cutting a log into planks in a sawmill
Rip cuts are commonly made with a table saw, but other types of power saws can also be used, including a radial arm saw, band saw, and hand held circular saw.In sawmills the head saw is the first rip-saw a log goes through, which is sometimes a gang-saw, and then the cants may be resawn using other saws and then edged in an edger and sometimes cut to length by a crosscut saw.

Log splitting is the act of splitting firewood from logs that have been pre-cut into sections (rounds, bolts, billets [3]). This can be done by hand, using an axe or maul, or by using a mechanical log splitter. [4] When splitting a log by hand, it is best to aim for the cracks (called checks), if there are any visible. [5]
