When all of the activities of the modern manufacturing plants are considered as a whole, it is impossible to think that a small portion might be automated, let alone trying to envisage automation of the whole.
In systems approach, a large and complex system with interacting components are analyzed and improved. The one who assigned with the responsibility of implementation of automation for complex system is advised to implement a technique similar to the traditional systems approach.
There are nine major elements of a CIM system are:
2. Product Design
5. Manufacturing Engineering
6. Factory Automation Hardware
9. Information Management
Manufacturing equipment such as CNC machines or computerized work centers, robotic work cells, DNC/FMS systems, work handling and tool handling devices, storage devices, sensors, shop floor data collection devices, inspection machines etc.
Massachusetts Institute of Technology (MIT, USA) is credited with pioneering the development in both CAD and CAM. The need to meet the design and manufacturing requirements of aerospace industries after the Second World War necessitated the development these technologies.
Computer Integrated Manufacturing (CIM) encompasses the entire range of product development and manufacturing activities with all the functions being carried out with the help of dedicated software packages. The data required for various functions are passed from one application software to another in a seamless manner.
Computer-aided design (CAD) is the use of computer systems to aid in the creation, modification, analysis, or optimization of a design.
