rather than every surface or every wire frame requiring individual shaping
(Unigraphics 1-1).

CAD/CAM software also creates N/C Programs for manufacturing. But, first
let’s define what CAM (Computer Aided Manufacturing) is, and how it is used
in the industry. CAM software is generally used for the creation of N/C
(Numerical Controlled) programs. N/C programs control machines that make
parts, such as rocket parts, car parts, and airplane parts. The CAM system
uses the CAD model to drive a tool, like a drill, through a hole in the
model. The N/C program is generated on the CAD/CAM system, then loaded
into a machine, that can drill and mill, thus producing a part per CAD/CAM
design (Unigraphics 1-2).
CAM systems have three basic types of operations for N/C
programming. First, are the drilling ...
