Give examples of "CNC" Computer Numerical Control production?

One of my best exciting CNC  process is the metallic tube bending machine 

used for the automotive's exhausts production.

Numerical control (NC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually via hand wheels or levers, or mechanically automated via cams alone. Most NC today is computer (or computerized) numerical control (CNC), in which computers play an integral part of the control.

In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a post processor, and then loaded into the CNC machines for production. Since any particular component might require the use of a number of different tools – drills, saws, etc., modern machines often combine multiple tools into a single "cell". In other installations, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine. In either case, the series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD design.

The most accurate measurements can be made by CNC machines in The Auto Industry, such as power steering pumps. All kinds of civil and military industry as well.

Agree with Mr.Vinod's answer

Thank you for the invitation, but I don't know much about this, and will leave it to the expert

I can only agree with the answers, but can also say that it is very beautiful and interesting to see how a CNC machine cuts his way into hard material to make the shape you see on the screen
