COMPUTER AIDED MANUFACTURING
The puter Aided Manufacturing (CAM) covers many areas from information processing and decision making to manufacturing and machining, which makes giving a single definition for CAM extremely difficult. D. Kochan gave a very fitting definition for CAM, with its diversity and wide range of use, in his book, “CAM can be defined puter-aided preparation of manufacturing including decision-making, process and operational planning, software design techniques, and artificial intelligence, and manufacturing with different types of automation (NC machine, NC machine centers, NC machining cells, NC flexible manufacturing systems ), and different types of realization (CNC single unit technology, DNC group technology ).”
Since CAM has such a wide range of uses, a better way to look at CAM is through CAM technologies. The CAM technologies covered are group technology, manufacturing database, automated and tolerancing.
The essential role of puter in the production function is to capture and process the data relating to a large number of transactions which continuously take place in different departments of pany. The initial research activity for CAM was Numerical Control (NC) for machine tools at the Massachusetts Institute of Technology in 1953. The first programming language was Automatically Programming Tools (APT) created at MIT, and it was the patt
