1. Computer Aided Design (CAD): 
Computer Aided Design (CAD) is the use of computers for designing models of physical products which means computers are used to aid in creating the design, modifying the design, and analyzing the designing activities. Computer Aided Design is also known as Computer Aided Drafting. The purpose of CAD is to make 2D technical drawings and 3D models. So in Simple, we can say CAD represents your part geometry to the computer. Computer Aided Design (CAD) software is mostly used by an engineer. 

Examples of CAD software include AutoCAD, Autodesk Inventor, CATIA, Solid Works, etc.

Computer + Designed Software = CAD 

2. Computer Aided Manufacturing (CAM): 
Computer Aided Manufacturing (CAM) is the use of computer software to control machine tools in the manufacturing of modules. CAM transforms engineering designs into end products. CAM is different than conventional manufacturing as it implements automation in the manufacturing process. Computer Aided Manufacturing is also known as Computer-Aided Modeling or Machining. The purpose of CAM is to use 3D models to design machining processes. So in Simple, we can say CAM converts the geometry to the machine tool. So, without Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM) has no meaning. Computer Aided Manufacturing (CAM) software is mostly used by a trained machinists. 

Examples of CAM software include Work NC, Siemens NX, Power MILL, SolidCAM, etc.

Manufacturing Tools + Computer = CAM 

Difference between CAD and CAM :

S.No.CADCAM
01.CAD refers to Computer Aided Design.CAM refers to Computer Aided Manufacturing.
02.CAD is the use of computers for designing means computers are used to aid in creating the design, modifying and analyzing the designing activities.Computer Aided Manufacturing (CAM) is the use of computer software to control machine tools in the manufacturing of modules. CAM transforms engineering designs into end products.
03.Computer Aided Design is also known as Computer Aided Drafting.Computer Aided Manufacturing is also known as Computer Aided Modeling.
04.The purpose of CAD is making 2D technical drawings and 3D models.The purpose of CAM is using 3D models to design machining processes.
05.Due to CAD it is much easier, more accurate and faster drafting, making 3D models impossible without computers.Due to CAM atomization in machining process is achieved.
06.So in Simple we can say CAD represents your part geometry to the computer.So in Simple we can say CAM converts the geometry to machine tool.
07.For Computer Aided Design process only a computer and CAD software are required for a technician to create a design.For Computer Aided Manufacturing computer and often a CAM software package along with that for manufacturing process requires a CAM machine.
08.Computer Aided Design (CAD) software is mostly used by an engineer.Computer Aided Manufacturing (CAM) software is mostly used by a trained machinist.
09.Some examples of CAD software includes AutoCAD, Autodesk Inventor, CATIA, Solid Works.Some examples of CAM software includes Work NC, Siemens NX, Power MILL, SolidCAM.
