The terms CAD and CAM are both important in computer-aided engineering and manufacturing, but they refer to different parts of the design and production process. CAD is an abbreviation for Computer-Aided Design to use of computer technology for design, while CAM is an abbreviation for Computer-Aided Manufacturing software used for machining or prototypes and finished parts.
Main difference:
The main difference between CAD and CAM is that CAM software is used by engineers while CAM is used by trained machinist are highly skilled and are equivalent to a computer engineer. They both are heavily dependent upon each other.
Difference between CAD and CAM :
- CAD make 2D technical drawings and 3D models while CAM using 3D models to design the machining process.
CAD responsibility :
2D and 3D design, Drafting, Detailing, All type of sheet metal and surface design.
CAM responsibility :
Manufacturing process after a design by using G code and M code, drilling, tapping, cutting, boring, milling, turning, and multiple operation processes perform on CAM software.
- CAD is much easier more accurate and fast drafting for 2D drawing but for 3D models impossible without computers whereas CAM is automization of the machining process.
- Require expensive software and knowledge on how to use it in both CAD and CAM. Software used by CAD and CAM is the following.
Software used by CAD :
Autodesk AutoCAD, Autodesk Inventor, Autodesk Fusion, SolidWorks, SolidEdge, CATIA, Creo, NX CAD
Software used by CAM :
EdgeCAM, NX CAM, Master CAM, CAMWorks
