Computer Aided Manufacturing (CAM) involves using computer systems to control manufacturing processes. It can help increase flexibility, reduce waste, and allow for smaller production lots. CAM evolved from numerical control in the 1950s and the development of computer-aided design. Computer Integrated Manufacturing (CIM) takes the integration further by combining computer technologies to manage all business and manufacturing functions as a single system, including design, planning, production, and business processes. CIM aims to make production more efficient, productive, and cost-effective through complete integration and automation.
