Which of the following is a potential benefit of computer-aided manufacturing?

• A. Increased energy use
• B. Larger parts inventories
• C. No waste reduction
• D. Increased production flexibility

Answer: (D)

Flexible production is a central advantage of computer-aided manufacturing. When machines, tools, and workflows are driven by computer control, the system can be reprogrammed and reconfigured quickly to handle different parts or designs without lengthy downtime. This means factories can switch between products, run small batches, or offer customization with shorter lead times and less disruption. That increased adaptability—being able to change what you make and how you make it without expensive retooling—is what this benefit captures.

Other potential outcomes listed aren’t typically viewed as benefits of CAM. While energy use, inventory levels, and waste are important factors in manufacturing, CAM’s value often lies in precision and flexibility: it can reduce waste through accurate, repeatable processes and lower the need for large inventories by enabling just-in-time production.
