Differences Between CAD and CAM with Examples

CADDEX India helps learners clearly understand the distinction between CAD and CAM—two essential components in modern engineering and manufacturing. CAD is about designing products, while CAM focuses on how those products are manufactured through automation and machine control.

What is CAD?

CAD (Computer-Aided Design) is the use of computer software to create 2D drawings or 3D models of physical components. It helps engineers visualize and simulate their designs before manufacturing.

Example: Using AutoCAD to create a floor plan or SolidWorks to model a gear assembly.

What is CAM?

CAM (Computer-Aided Manufacturing) is the use of software to convert CAD models into toolpaths and machine instructions (G-code) for CNC machines, enabling automated production.

Example: Using Mastercam or Fusion 360 CAM to generate CNC code for milling a metal bracket.

CAD vs CAM – Comparison Table

Aspect	CAD (Computer-Aided Design)	CAM (Computer-Aided Manufacturing)
Purpose	Design and modeling of products	Manufacturing and machining of products
Focus	Geometry, dimensions, aesthetics	Toolpaths, speeds, feeds
Software Examples	AutoCAD, SolidWorks, CATIA	Mastercam, Fusion 360 CAM, NX CAM
User	Design engineers, architects	CNC programmers, machinists
Output	2D drawings, 3D models	G-code, NC files, toolpath simulations

How CAD and CAM Work Together

The integration of CAD and CAM allows for a seamless transition from design to production. A 3D model created in CAD is directly imported into CAM software to generate toolpaths and machine instructions—saving time and reducing errors.

Example Workflow: Design a component in SolidWorks → Import into Mastercam → Generate G-code → Run on CNC machine.
