Computer-integrated manufacturing (CIM) refers to the use of computer-controlled machineries and automation systems in manufacturing products. CIM combines various technologies like computer-aided design (CAD) and computer-aided manufacturing (CAM) to provide an error-free manufacturing process that reduces manual labor and automates repetitive tasks. The CIM approach increases the speed of the manufacturing process and uses real-time sensors and closed-loop control processes to automate the manufacturing process. It is widely used in the automotive, aviation, space and ship-building industries.
Computer Integrated Manufacturing applies principles of rapid prototyping (Techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data.), robotics, and automation. CIM builds upon CAD solid modeling skills developed in the first section. Students will use computer controlled rapid prototyping and CNC equipment to solve problems by constructing actual models of their three-dimensional designs. Students will also be introduced to the fundamentals of robotics and how this equipment is used in an automated manufacturing environment. Students evaluate their design solutions using various techniques of analysis and make appropriate modifications before producing their prototypes. The CNC stands for Computer Numerical Control. CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include Lathes, Mills, Routers, Electrical Discharge Machines (EDM) and Water, Plasma & Laser Cutters, as well as Grinders.

CIM is a manufacturing approach that provides a complete automation of a manufacturing facility. All the operations are controlled by computers and have a common storage and distribution. CIM is a combination of different applications and technologies like CAD, CAM, computer-aided engineering, robotics, manufacturing resource planning and enterprise management solutions.
Computer Aided Manufacturing (CAM) is the use of software and computer-controlled machinery to automate a manufacturing process. In a world full of physical stuff – whether that’s products, parts, or places – Computer Aided Manufacturing (CAM) makes it all possible. We’re the ones that give the power of flight to airplanes, or the rumble of horsepower to automobiles. When you need something made, not just designed, CAM is your answer. Computer-aided manufacturing (CAM) also known as Computer-aided Modeling or Computer-aided Machining is the use of software to control machine tools and related ones in the manufacturing of work pieces.
