What type of system uses information from CAD drawings to produce parts and assemblies?

The correct answer is CAM, which stands for Computer-Aided Manufacturing. This system takes information from CAD (Computer-Aided Design) drawings to help produce parts and assemblies. CAD drawings provide detailed designs and specifications, while CAM software processes this information to create the necessary tool paths and operational instructions for manufacturing processes.

CAM plays a crucial role in modern manufacturing, as it automates the production workflow and enhances precision, speed, and efficiency. By integrating CAD and CAM, manufacturers can streamline their processes, leading to reduced errors and improved product quality.

While CNC (Computer Numerical Control) refers to the machines that are controlled by computer programs for machining parts, and 3D printers are specific devices that build three-dimensional components layer by layer, they do not directly address the broader system that utilizes CAD drawings in a manufacturing context like CAM does. CAD itself is a design tool rather than a system for producing parts. Therefore, CAM is the most accurate choice for the process described in the question.
