I have worked on massive beam saws that cut up to 8 sheets stacked of wood per pass (CNC
X/Y), (Holz Her, Homag, Holzma), wild stuff. Massive motors, induction. They use current
sensors (PLC) to measure how dull the blade is.

I watched one of these saws being commissioned once. The do-or-die
moment is when the saw generates its _own_ blade-guide by cutting
through the load-beam, a 4" square box channel about ten feet long.
Made a huge noise and attracted everybody in the factory, fingers in
ears and cigarettes on lips. The ceremony is especially important to
those who checked blade's axial runout.
