Do I need to compensate for kerf in my design?

Kerf is the additional material removed by the cutting tool in the machining process. Think of a saw cutting through a piece of wood. The saw cuts through the wood where you need it cut, but it also “pushes” aside some of the wood due to the width of the blade. That is “kerf.” Laser cutter kerf is the width of the laser beam plus the small amount of additional material burned away by the heat. But be it a laser, waterjet, or CNC router, all machining processes have a small amount of kerf.
