CNC mills are used to cut shapes with a spinning blade from wooden, but also plastic and metal, panels. CNC mills translate a 2D or 3D computer drawing in a cut shape or engraving.

They were developed from the 70s for mass manufacture, but have become common also for small scale production, thanks to the availability of smaller and more affordable units and to the spreading of computer use in design.

The acronym CNC stands for Computer Numerical Control and refers to a family of manufacturing machines operated by computer programs, that includes CNC mills, laser cutters, 3D printers and waterjet cutters.
