Difference Between CAD and CAM


CAD

Computer - Aided Design (CAD) cam be defined as the creation, modification, analysis and optimization of a new component using a computer.

 CAD involves three major elements :-
1. Hardware
2. CAD software
3. The user

 The primary function of CAD involves design, analysis and application to manufacturing. An object drawn with CAD can be analysed interactively on the CAD screen and the physically information can be extracted from it.
In an engineering sense, CAD also incorporates finite element analysis, stress analysis, heat transfer analysis, and fluid flow analysis and so on i.e which enables a part to be constructed and tested virtually before and physically object is manufactured.

CAM

Computer- Aided manufacturing (CAM) can be defined as the application of computers to plan, process, manage and control various operations in a manufacturing organization either with direct or indirect computer interface with the available resources.

Wire Drawing

Introduction In drawing, the cross section of a long rod or wire is reduced or changed by pulling (hence the term drawing) it through a die called a draw die (Fig. 7.1). Thus, the difference between drawing and extrusion is that in extrusion the material is pushed through a die, whereas in drawing it is pulled through it. Although the presence of tensile stresses is obvious in drawing, compression also plays a significant role because the metal is squeezed down as it passes through the die opening. For this reason, the deformation that occurs in drawing is sometimes referred to as indirect compression. Drawing is a term also used in sheet metalworking. The term wire and bar drawing is used to distinguish the drawing process discussed here from the sheet metal process of the same name. Rod and wire products cover a very wide range of applications, including shafts for power transmission, machine and structural components, blanks for bolts and rivets, electrical wiring, cables,.....
