How do you operator the cnc machine?

Well there are a few different types one is an opperator controlled that means that the opperator has to phisicly (?) hold buttons down to make the router move another type you input cooradanets or a design in to a computer program wich does the "button pushing" for you those two move the router not the material for you but another while technecly not a cnc moves the material being cut or milled. hope this helps. cgul
