Computer aided manufacturing is used by companies to

Companies use computer-aided manufacturing to create a 3D model of new or existing products, while using CAD software helps them finalize the design and shape the product prior to suitable production. You can use computer-aided manufacturing to simulate the production process and test designs with a CAD system.

Computer-aided manufacturing (CAM) is the use of software to control machine tools in the manufacturing of workpieces. Its primary purpose is to speed the production process and produce components and tooling with more precise dimensions and material consistency.

Its primary purpose is to create a faster production process and components and tooling with more precise dimensions and material consistency, which in some cases, uses only the required amount of raw material (thus minimizing waste), while simultaneously reducing energy consumption.
