A tree enters a sawmill as a massive round log.

Minutes later, it can emerge as precisely cut boards, stacked, sorted, and ready for construction.

But turning a raw log into usable lumber requires an enormous coordinated system of machines.

In Engineering Insights S2 E88, we explore the engineering behind modern sawmills and how automated lumber processing systems transform logs into finished wood products.

We follow the process from the log yard to the finished stack, examining debarkers, conveyors, saws, scanners, edgers, trimmers, sorters, and stacking systems.

The first challenge is understanding the log itself.

Modern sawmills use scanners and computer systems to measure diameter, length, shape, and defects.

Software can then determine how the log sh ...
