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.
Overview
Both CAD and CAM are computer-intensive. Although, in 1981, Computervision was #1 and IBM was #2, IBM had a major advantage: it's systems could accomodate "eight to 20" users at a time, whereas most competitors only had enough power to accomodate "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 and Parametric Technology Corporation; the latter subsequently acquired Computervision, which had been acquired by Prime Computer.
CAD/CAM originated in the 1960s; an IBM 360/44 was used to build via CNC the wings of an airplane.
Computer-aided design (CAD)
Main article: Computer-aided designOne goal of CAD is to allow quicker iterations in the design process; another is to enable smoothly transitioning to the CAM stage. Although manually created drawings historically facilitated "a designer's goal of displaying an idea," it did not result in a machine-readable result that could be modified and subsequently be used to directly build a prototype. It can also be used to "ensure that all the separate parts of a product will fit together as intended."
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."
Computer-aided manufacturing (CAM)
Main article: Computer-aided manufacturing
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. Early 21st century CAM introduced use of 3D printers.
