Which of the following is NOT an advantage of CAD/CAM?

• A. Expensive setup cost
• B. Easy to display ideas to client
• C. High accuracy
• D. Speeds up the development process

Answer: (A)

CAD/CAM offers benefits that improve communication, precision, and speed in production. One major advantage is that CAD models and rendered images let you show and tweak ideas easily with a client, helping everyone agree on the design before manufacturing. Another key benefit is high accuracy: digital designs translate into precise, repeatable parts with less human error. A third plus is that development moves faster—automatic tool paths, rapid prototyping, and streamlined workflows shorten the time from concept to finished product.

Expensive setup cost, however, is a barrier rather than a benefit. The initial investment in software, hardware, licenses, and training can be substantial, which is why it’s not considered an advantage of CAD/CAM.
