CAD/CAM Revolutionizes Engineering and Manufacturing (Great Events from History II: Business and Commerce Series)
Article abstract: Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) enhanced flexibility in engineering design, leading to higher quality and reduced time for manufacturing.
Summary of Event
Computer-Aided Design (CAD) is a technique whereby geometrical descriptions of two-dimensional (2-D) or three-dimensional (3-D) objects can be created and stored, in the form of mathematical models, in a computer system. Points, lines, and curves are represented as graphical coordinates. When a drawing is requested from the computer, transformations are performed on the stored data, and the geometry of a part or a full view from either a two- or a three-dimensional perspective is shown. CAD systems replace the tedious process of manual drafting, and computer-aided drawing and redrawing that can be retrieved when needed have improved drafting efficiency. A CAD system is a combination of computer hardware and software that facilitates the construction of geometric models and, in many cases, their analysis. It allows a wide variety of visual representations of those models to be displayed.
Computer-Aided Manufacturing (CAM) refers to the use of computers to control, wholly or partly, manufacturing processes. In practice, the term is most often applied to computer-based developments of numerical control technology; robots and flexible manufacturing systems (FMS) are included in the broader use of CAM...
