The correct answer is D. All of the above.
A numerical control (NC) system is a type of automation that controls machine tools by using a numerical control program. The program is a set of instructions that tells the machine tool how to move and what to do. The NC system consists of a controller, a tape input, and a machine tool.
The controller is the brains of the NC system. It interprets the program and sends the appropriate signals to the machine tool. The tape input is a device that reads the program from a punched tape. The machine tool is the device that actually performs the machining operations.
NC systems are used in a wide variety of industries, including manufacturing, aerospace, and automotive. They are used to produce a variety of products, including parts for cars, airplanes, and medical devices.
Here is a brief explanation of each option:
- Controller: The controller is the brains of the NC system. It interprets the program and sends the appropriate signals to the machine tool.
- Tape input: The tape input is a device that reads the program from a punched tape.
- Machine tool: The machine tool is the device that actually performs the machining operations.
