What does "computer-aided manufacturing" (CAM) refer to?

Computer-aided manufacturing (CAM) refers specifically to the use of software to control machine tools and related machinery in the manufacturing process. This technology enhances production efficiency by automating processes that would otherwise require manual input or be done inefficiently. CAM systems allow for precise control over manufacturing equipment, enabling the operation of machinery to be highly accurate and repeatable. This can lead to improved product quality, reduced lead times, and greater production flexibility.

In contrast, the other options do not accurately describe CAM. Designing marketing materials typically involves graphic design tools rather than manufacturing processes. Manual control of machinery implies an absence of software assistance, which contradicts the core concept of CAM, while a method for quality assurance focuses on monitoring and maintaining product standards rather than the production aspect itself.
