Computer-aided design and computer-aided manufacturing software (CAD/CAM) is used in mechanical, electrical, and electronic design; simulation, drafting, and engineering; and design analysis and manufacturing.
Lathes and turning centers cut a rotating part with a stationary cutting tool. The tool moves parallel and perpendicular to the workpiece axis to provide the desired finished shape.
Milling machines move a clamped workpiece into a fixed, rotating cutter; or move the cutter itself into a stationary workpiece. There are two basic configurations: vertical and horizontal.
