What type of machine did Leonardo da Vinci design to cut wood automatically?

Leonardo da Vinci designed a hydraulic saw to cut wood using water power.

The machine was intended to automate sawing by combining a water-driven mechanism with a saw blade and a system for moving timber. Water wheels were already used in mills, but Leonardo’s design applied hydraulic power to a more coordinated cutting process.

The hydraulic saw is best understood as a mechanical design study, not proof that Leonardo invented every later type of saw. A modern circular saw, band saw, or chain saw has a different cutting mechanism and should not be substituted for the historical machine.

The design illustrates Leonardo’s interest in replacing repetitive human labor with controlled mechanical motion. His notebooks contain many such studies involving cams, gears, cranks, and water power, often linking several moving parts into one proposed machine.
