In the fields of engineering and manufacturing, CAD/CAM software is a type of computer program used to design and produce items. Computer-Aided Manufacturing is often known as CAM, while CAD stands for computer-aided design.

2D or 3D models of goods or parts are produced using CAD software. Before a product is ever created, it allows engineers and designers to visualize and alter its design. Sketches, wireframes, and intricate models of individual components or assemblies can be produced as part of this process.

On the other side, CAM software is utilized to regulate and automate the production process. The physical product is produced using toolpaths and instructions produced by CNC (Computer Numerical Control) machines, lathes, and milling machines using the digital design developed in CAD software.

Collectively, CAD/CAM software offers a potent toolkit for product development and production, empowering engineers and designers to efficiently and accurately build complex items. It is utilized in a variety of sectors, including consumer goods, electronics, and the automobile and aerospace industries.
