On a certain level, computer-aided design (CAD) and computer-aided manufacturing (CAM) have similar purposes in the engineering world. However, there are distinct differences for each under the MasterCam software.While there are differences, both CAD and CAM use computer-based methods to encode geometrical data. Therefore, it is possible to integrate design and manufacture processes. Systems that combine both are more commonly called CAD/CAM.CAD DescriptionCAD involves computer models created by geometrical parameters where the models appear on a computer monitor. As a 3D representation either of a part or system of parts, either one can be altered when relevant parameters are changed. Designers use CAD systems to view objects. They appear under a broad variety of representations that are tested by simulating real-world events.

CAM Description For CAM, geometrical design data is used to control the maneuvers of automated machinery. These systems are usually associated with direct numerical control (DNC) or computer numerical control (CNC) systems. CAM systems are different from older forms of numerical control. Geometrical data is encoded mechanically.Advantages and Disadvantages to Using These Systems Using CAD systems for modeling have many advantages over using traditional drafting methods that required compasses, squares and rulers. Now, designs are altered without having to erase and redraw. Additionally, CAD systems have zoom features similar to a camera lens. With this feature, a designer can enlarge specific elements to facilitate the inspection process.Using CAD systems for modeling have many advantages over using traditional drafting methods that required compasses, squares and rulers.

Additionally, CAD systems have zoom features similar to a camera lens. With this feature, a designer can enlarge specific elements to facilitate the inspection process.CAD systems can also be used for modeling cutaway drawings. With these, the internal shape of parts are revealed to illustrate spatial relationships among the different parts of the system.Typically, it helps to understand CAD from the viewpoint of what it cannot do. Using this system offers no means of comprehending real-world concepts. An example of this is the nature of an object that is being designed with the system.Recent developments are beginning to fundamentally impact the use of CAD/CAM systems. For starters, personal computers now have increased processing power, which makes them a perfect vehicle to house the CAD/CAM application. Evolution of integration and visual representation of modeling applications are also expanding the use of these systems.
