Difference between CAD and CAM

February 11, 2023

The main difference between CAD and CAM is, CAD (Computer-Aided Design) is used for design and product visualization, while CAM (Computer-Aided Manufacturing)is used for the actual manufacturing of the product.

CAD is a software-based design tool that is used by engineers, designers, and architects to create 2D and 3D models of products and structures.

In this article, we will highlight all the points that differentiate CAD from CAM software. Let’s start with some basics of CAD and CAM.

CAM is a software-based manufacturing tool that is used to control and automate the production process. It helps to convert the design of a product created on a computer into machine-readable code. This code is used by machines to create the actual product.

What is CAD?

Computer-Aided Design is the full form of CAD. Computer-aided design is a way to use computers to modify or improve a design. CAD software allows designers to visualize, simulate, and analyze their designs before they are manufactured.

With CAD, designers can create detailed and accurate drawings, technical specifications, and simulations to test their designs for function, performance, and reliability.

What is CAM?

CAM stands for Computer-Aided Manufacturing. it is a software-based tool that is used to control and automate the production process in manufacturing industries.

CAM is used to convert the design created in CAD (Computer-Aided Design) into machine-readable code, called G-code, which is then used by computer numerical control (CNC) machines to fabricate the product.


The main differences between CAD and CAM are given below:
