2. History of numerical control - Wikipedia

   en.wikipedia.org/wiki/History_of_numerical_control

   The history of numerical control (NC) began when the automation of machine tools first incorporated concepts of abstractly programmable logic, and it continues today with the ongoing evolution of computer numerical control (CNC) technology.

3. CNC wood router - Wikipedia

   en.wikipedia.org/wiki/CNC_wood_router

   A CNC wood router uses CNC (computer numerical control) and is similar to a metal CNC mill with the following differences: The wood router typically spins faster — with a range of 13,000 to 24,000 RPM; Professional quality machines frequently use surface facing tools up to 3" in diameter or more, and spindle power from 5 to 15 horsepower.

4. Numerical control - Wikipedia

   en.wikipedia.org/wiki/Numerical_control

   A CNC machine that operates on wood CNC machines typically use some kind of coolant, typically a water-miscible oil, to keep the tool and parts from getting hot. A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control (CNC), [1] is the automated control of tools by means of a computer. [2]

5. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   The operating system of such machines is a closed loop system and functions on feedback. These machines have developed from the basic NC (NUMERIC CONTROL) machines. A computerized form of NC machines is known as CNC machines. A set of instructions (called a program) is used to guide the machine for desired operations.

6. CNC router - Wikipedia

   en.wikipedia.org/wiki/CNC_router

   The CNC Router is ideal for hobbies, engineering prototyping, product development, art, and production works. The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control; however, typical CNC operated systems can only make carvings on flat planes. The machine sits on a track and is not capable of making round or spherical cuts.

7. Automatic lathe - Wikipedia

   en.wikipedia.org/wiki/Automatic_lathe

   By the 1980s, true CNC screw machines (as opposed to simpler CNC lathes), Swiss-style and non-Swiss, had begun to make serious inroads into the realm of cam-op screw machines. Similarly, CNC chuckers were developed, eventually evolving even into CNC rotary transfer machines. These machine tools are little known outside the automotive ...
