Explain CAD/CAM and how it is used.
What will be an ideal response?
Some industries tie their engineering and manufacturing departments together using a CAD/CAM linkup over a computer network. CAM stands for computer-aided manufacturing. In this process, the drafting department designs a product on a computer. After completion, the drawing is converted to coordinate data and then stored. Additional software called a post processor then converts the stored coordinate data into a usable format for the machines in the manufacturing department. Hardcopy is not produced unless someone needs to study the drawing away from a computer terminal.
