Overview and History of CAD/CAM - CAD and CAM are computer-intensive. - IBM had an advantage in the 1980s as its systems could accommodate more users compared to competitors. - CAD/CAM was pioneered by Computervision in the 1970s. - General Electric and Parametric Technology Corporation were major players in CAD/CAM in the 1980s. - CAD/CAM originated in the 1960s with the use of an IBM 360/44 to build airplane wings.

Computer-aided design (CAD) - CAD allows quicker iterations in the design process. - It enables a smooth transition to the CAM stage. - Manually created drawings historically did not result in a machine-readable result. - CAD ensures that all parts of a product fit together as intended. - CAD, when linked with simulation, can bypass the need for building a prototype.

Computer-aided manufacturing (CAM) - CAM uses computerised specifications to direct machines such as lathes and milling machines. - CAM originated in the 1960s with Numerical Control (NC or CNC). - Early 21st-century CAM introduced the use of 3D printers. - CAM reduces labor costs and enables a speedy transition from CAD to finished products. - CAM ensures a high machining success rate.
