CAD/CAM

Both CAD and CAM are computer-intensive. Although, in 1981, Computervision was #1 and IBM was #2, IBM had a major advantage: its systems could accommodate "eight to 20" users at a time, whereas most competitors only had enough power to accommodate "four to six." CAD/CAM was described by The New York Times as a "computerized design and manufacturing process" that made its debut "when Computervision pioneered it in the 1970's."

Other 1980s major players in CAD/CAM included General Electric{{cite news |newspaper=The New York Times

CAD, when linked with simulation, can also enable bypassing building a less than satisfactory test version, resulting in having "dispensed with the costly, time-consuming task of building a prototype."{{cite news

In Computer-aided manufacturing (CAM), using computerized specifications, a computer directs machines such as lathes and milling machines to perform work that otherwise would be controlled by a lathe or milling machine operator. This process, which is called Numerical Control (NC OR CNC), is what came to be known as 20th century Computer-aided manufacturing (CAM), and it originated in the 1960s.{{citation needed|date=August 2022}} Early 21st century CAM introduced use of 3D printers.{{cite journal

CAM, although it requires initial expenditures for equipment, covers this outlay with reduced labor cost and speedy transition from

CAD to finished product, especially when the result is both timely and "ensuring one-time machining success rate."{{cite web
