Which device is used to input data in a CNC system?

• A. Keyboard
• B. Mouse
• C. Control Panel
• D. Touchscreen

Answer: (C)

CNC data entry happens through the control panel, the built-in interface that communicates directly with the machine’s controller. Operators input programs, offsets, tool data, feed rates, spindle speeds, and other parameters using the keys, displays, and jog controls on the panel. A keyboard or mouse may exist on some setups, but those peripherals aren’t the standard control interface—the control panel is designed for direct machine data entry and control, including MDI, program start/stop, and axis jogging. In newer systems, a touchscreen can be part of the control panel, but the essential point is that data to the CNC is entered via that integrated panel. That’s why the control panel is the best answer.
