What Is CNC, Anyway?

A CNC (Computer Numeric Control) tool is used in prototyping and full production for cutting, carving, machining and milling in wood, MDF, plastics, foams, and aluminum.

With a ShopBot CNC tool, you use the included software to design your parts on your personal computer, then, like a robot, the computer controls the cutter to precisely cut your parts. In the past, CNC tools were strictly industrial tools only used in large factory settings. Now, all the types of computer-driven tools that create things by cutting material away (such as CNCs or laser cutters) or building up material in layers to create an object (3D printing) are called digital fabrication tools. ShopBot's innovations in CNC technology have made these powerful tools affordable for individuals and small shops.

How CNC Works

ShopBot Tools, like all CNC tools, move a cutter around a big table (X and Y axes) and move it up and down as well (Z axis) allowing it to make 3D movements and cut all sorts of shapes. The cutter looks like a drill bit and is spun by a motor called a router or spindle. Unlike a drill bit, a router bit is designed to cut from the sides as well as the tip. By precisely moving the cutter through material, a ShopBot CNC tool can create virtually any pattern or shape and will do it in materials such as wood, plastic, foam, aluminum and many composites.

  • A ShopBot CNC can cut material in the same way you would with a saw. It can cut in the X or Y direction ...

  • Or on any diagonal. It can also make the cut at any depth, or even at varying depths. 

  • A ShopBot can also cut circles and holes. These can be any size from as small as the size of the cutter itself to the size of the whole table. It can also cut arcs, ellipses and curves - at any depth or at varying depths within the cut.

  • arches… 

  • …or chair parts

  •  

    In short, a ShopBot can cut any type of shape you can draw - a shape with any level of complexity.

  • What is sometimes surprising to those experienced with traditional tools:  It is just as easy for a ShopBot CNC to cut a curved or complex shape as it is for it to cut a straight line.
