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.

CAD/CAM refers to the integration of Computer-aided design (CAD) and Computer-aided manufacturing (CAM). Both of these require powerful computers. CAD software helps designers and draftsmen; CAM "reduces manpower costs" in the manufacturing process.
