Computer Numerical Control or the CNC machine tool refers pecifically to a computer "controller" that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material.
What are the types of CNC machine tools? Here are tools with CNC variants:
* Drills - a tool with a rotating drill bit used for drilling holes in various materials.
* EDMs - Electrical discharge machining. A machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques.
* Lathes - a machine tool which spins a block of material to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation.
* Milling machines - a machine tool used for the complex shaping of metal and other solid materials.
* Wood routers - typically holds wood with suction through the table or pods that raise the work above the table. This type of hold-down is used for components which require edge profiling (or undercutting).
* Sheet metal works(Turret Punch)- simply metal formed into thin and flat pieces.
* Wire bending machines
* Hot-wire foam cutters - a tool used to cut polystyrene foam and similar materials.
* Plasma cuttings - a process that is used to cut steel and other metals (or sometimes other materials) using a plasma torch.
* Water jet cutters - a tool capable of slicing into metal or other materials using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance.
* Laser cutting - a technology that uses a laser to cut materials, and is usually used in industrial manufacturing.
* Oxy-fuel - Oxy-fuel cutting are processes that use fuel gases and oxygen to either weld or cut metals.
