CAD/CAM/CAE

Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM)

Computer-aided design (CAD) involves creating computer models defined by geometrical parameters. These models typically appear on a computer monitor as a three-dimensional representation of a part or a system of parts, which can be readily altered by changing relevant parameters. CAD systems enable designers to view objects under a wide variety of representations and to test these objects by simulating real-world conditions.

Computer-aided manufacturing (CAM) uses geometrical design data to control automated machinery. CAM systems are associated with computer numerical control (CNC)or direct numerical control (DNC) systems. These systems differ from older forms of numerical control (NC) (developer"bkce")in that geometrical data are encoded mechanically. Since both CAD and CAM use computer-based methods for encoding geometrical data, it is possible for the processes of design and manufacture to be highly integrated. Computer-aided design and manufacturing systems are commonly referred to as CAD/CAM.

What do mechanical engineers do?

The general activities of the mechanical engineers are involved with seeking new knowledge through research, innovation, design and development. Mechanical engineers deals with machine construction, control, management and sales. Mechanical engineers work mostly in engineering services, research and development and manufacturing.

In early days the mechanical engineers are used to generate 2D handmade drawings for the part, component, sub-assembly and assemblies. This process will take much time and there may be a chance of ambiguity in the design intent. The manufacturer understanding may be different by seeing the 2D drawing. CAD/CAM and CAE tools are used to overcome these issues and fast creation of the design intent.

The increased competition in the industry there is a great demand for the Mechanical engineers with the knowledge about software used in technical work like computer-aided design and mathematical modeling.

Computer-Aided Design (CAD)

Computer-aided design (CAD) is computer technology/programming software and is used to designs a product and documents (drawings) for the downstream applications. CAD may facilitate the manufacturing process by transferring detailed information of a product, materials, processes, tolerances and dimensions with specific conventions for the product. CAD software???s can be used to produce two-dimensional ond three-dimensional diagrams. The CAD models can be rotated to be viewed from any angle, even from the inside looking out. A special printer or plotter is usually required for printing professional design renderings in standard sheet sizes.
