Which of the following statements about CAM systems is true?

The statement regarding CAM (Computer-Aided Manufacturing) systems that is true is that they enhance the precision of manufacturing processes. CAM systems utilize computer software and machinery to automate manufacturing tasks, enabling a high level of accuracy and consistency that is difficult to achieve with manual methods. This precision is crucial in industries where exact specifications are necessary, such as aerospace, automotive, and medical device manufacturing.

By controlling machinery through computer programs, CAM systems can produce complex parts with tight tolerances, reduce human error, and improve overall production efficiency. This technological approach allows manufacturers to better meet quality standards and customer demands, which is a significant advantage in competitive markets.

The other statements do not accurately reflect the capabilities or characteristics of CAM systems. For instance, while CAM systems automate processes, they do not eliminate the need for manual labor entirely, as operators are often required for oversight and quality control. Additionally, CAM systems are indeed used for production rather than just design; they are part of the production process after the design phase has been completed. Moreover, like most software systems, CAM systems do require updates to improve functionality and security over time.
