Definition
The use of computers to control machine tools and production equipment used in the fabrication of aircraft parts and components. Computer-Aided Manufacturing systems take design data, often produced by Computer-Aided Design software, and translate it into precise instructions that drive cutting, milling, drilling, and shaping machinery on the factory floor.
Plain English
Using computers to run the machines that actually build aircraft parts. The computer tells the machine exactly how to cut, drill, or shape the metal, instead of a person operating the controls by hand.
Context Anchor
Seen in aircraft manufacturing, parts production, maintenance documentation, and discussions of how approved replacement parts are made.
Derivation
Manufacturing comes from the Latin manu (hand) and facere (to make) — literally 'made by hand.' Computer-Aided Manufacturing flips that origin: the work is still made, but the computer guides the machinery rather than a human hand.
Why Pilots Care
Parts produced through Computer-Aided Manufacturing are highly consistent and tightly toleranced, which contributes to the reliability and interchangeability of components in modern aircraft.
Example Sentence 1
The engine cylinder heads were produced using Computer-Aided Manufacturing to ensure consistent dimensions across the entire production run.
Example Sentence 2
Inspectors verified that the engine mounts had been produced using computer-aided manufacturing before installation on the aircraft.
