Computer-aided manufacturing energy consumption. CAM is now a system used in schools and lower educational purposes. CAM is a subsequent computer-aided process after computer-aided design (CAD) and sometimes computer-aided engineering (CAE), as the model generated in CAD and verified in CAE can be input into CAM software, which then controls the machine tool. CAM is used in many schools alongside Computer-Aided Design (CAD) to create objects. Traditionally, CAM has been considered as a numerical control (NC) programming tool, where in two-dimensional (2-D) or three-dimensional (3-D) models of components generated in CAD. As with other “Computer-Aided” technologies, CAM does not eliminate the need
Computer-assisted reporting edition of which was written in 1969, Philip Meyer argues that a journalist must make use of databases and surveys, both computer-assisted. In the 2002 edition, he goes even further and states that "a journalist has to be a database manager". In 2001, computers had reached a critical mass in American newsrooms in terms of general computer use, online research, non-specialist content searching, and daily frequency of online use, showing that CAR has become ubiquitous in the United States. The techniques expanded from polling and surveying to a new opportunity for journalists: using the computer to analyze huge volumes of
