Computer Numerical Control
/ˌsiː-en-siː/
n. “The automated control of machine tools using computer-generated instructions.”
CNC, short for Computer Numerical Control, refers to the use of computers to control machine tools with high precision and repeatability. Instead of being operated manually, CNC machines follow a programmed set of instructions that dictate exact movements, speeds, and tool actions.
Computer-Aided Manufacturing
/kæm/
n. “The use of computers to turn digital designs into machine instructions.”
CAM, short for Computer-Aided Manufacturing, refers to software systems that convert digital design data, most commonly from CAD, into instructions that control manufacturing equipment. CAM bridges the gap between a virtual model and a physical object by translating geometry into toolpaths, feeds, speeds, and machine movements.
