What is the Difference between CAD vs CAM vs CAE

CAD CAM and CAE are the tools used to assist engineers in design, manufacturing and engineering calculations. Each of these tools has their own applications. In this article we will discuss what is the difference between CAD vs CAM vs CAE.

Computer Aided Design (CAD) tools utilizes highly powered computers to design, visualize and simulate new product designs.

Using CAD software engineers can build entire product designs in the virtual world (computer screen) where they can visualize and review it to deliver first time right products. Solidworks, AutoCAD, Catia, and Creo etc. are the examples of CAD tools that are used to create CAD designs. We suggest you also read this article on cloud based cad software.

What is CAM?

CAM or Computer-Aided-Manufacturing softwares are used to automate the manufacturing process. CAM software takes a part cad design as input and converts it into instructions such as G-codes that a machine can understand. 

Computer aided manufacturing software are used to:

  • Generate codes that a machine can understand.
  • Increase machine efficiency by optimizing the tool path.
  • Effective utilization of raw material.

What is CAE?

CAE or computer-aided-engineering tools are used to simulate a product design before building real prototypes. This is done to ensure product design is first time right and deliver it faster in the market. Examples of CAE software are FEA, CFD, MDO etc. 

CAE Software are used to:

  • Analyze a System behavior before building the actual prototype.
  • Reduces manufacturing cost.
  • Faster products to the market.
  • Solving complex engineering problems quickly
  • Value engineering etc.

What is the difference between CAD vs CAM vs CAE?

These days all of these tools CAD CAM and CAE are integrated into one software. For example, solidworks and fusion360 have features of CAD, CAM and CAE. Integrating all of these features in one software streamline the complete product design and development process. To become a good mechanical design engineer one should have basic knowledge of all of these tools.
