Computer numerical control: using programmed numerical instructions to control machine movements.

Paper 1
Computer numerical control: the control of a machine's movements and operations through programmed numerical instructions.
Revise: IndustryCNC mills, routers and lathes use programmed instructions to guide operations such as cutting and shaping. Compared with manually controlling each movement, this supports accurate, repeatable manufacture.
Do not claim that CNC guarantees perfect results: accurate programming, suitable tooling and secure workholding still matter.
Explain repeatability rather than simply saying 'accurate': a template or CNC program guides production so components have the same shape and dimensions.
For repeated CNC milling, explain that the program repeats the same controlled tool paths on each workpiece.
