solved assignments for Q.Explain briefly the Computer Integrated Manufacturing


Answer: Computer Integrated Manufacturing
Integration occurs when a broad range of manufacturing and supporting activities are linked.
Activities include engineering design, production planning, shop control, order processing, material control, distribution etc. Information flow across all functions takes place with the help of computers. Transmission, processing, distribution and feed back happen almost in real time so that intended activities are conducted rapidly. This process helps in rapid production and also reduce indirect costs. As response times decrease, customer satisfaction increases resulting in better business. CIM helps in avoiding accumulation of materials resulting in better throughput and better utilization of space. Bar coded labels that accompany materials contain instructions for processing them which are read by sensing devices and display the status on monitors. This information is available to all concerned personnel responsible in planning, marketing etc. so that they will be aware of the status of any order and if expediting is needed to meet deadlines, they will be able to seek intervention. Identifying shortages, ensuring faster deliveries becomes easy with CIM.

One of the keys to success in the manufacturing business is to lessen errors and to enhance productivity. The more one can produce with fewer flaws, the more one can make at the bottom line. Over a period of time factory owners have integrated computer systems in order to streamline the production process. CAD, or computer aided design, has been able to aid the operators in the formulation and blueprints of more sophisticated products and technology.

CAM, or computer aided manufacturing, has offered the means by which to produce the more sophisticated items. CAM also enhances the productivity of the factory's output. Together the CAD and CAM systems reduce cycle times, enhance productivity, and aid in the streamlining of the overall production process.

Since the 1980's CAD and CAM have worked together to move from the idea phase to the application phase. This process has not ceased because of the implication. The factory sector has slowly been phasing in computer integrated manufacturing, or CIM over the years. This integration will allow for the digital information and computer control of the production process to be intertwined throughout and within the factory.

In the CIM system some processes will be different. Data entry will now be stored in hard drives. This will allow for the manipulation and the retrieval of the data with a simple keystroke. The means by which the processing of data into the production of products will also be streamlined within hardware and software. This will allow operators to alter and enhance programs in order to improve products. The CIM system will also provide the necessary algorithms to bring all the data together. The data will then be able to intermingle with the sensor and modification components of the system.

While the CIM system is the optimal choice to aid in the manufacturing process, it does come with a unique set of challenges. The greatest challenge is to get all the different machines within the factory to work on the same system. In the typical factory, there are a variety of machines that perform different tasks, that are made by a variety of suppliers. The issue is to get every one of these machines to accept the programming, and tasks from one mainframe computer.

The second challenge of the CIM system is encapsulated within the data itself. While many operators may be lost on the actual production floor, there will be a need for operators to maintain the integrity of the data that is transmitted to the machines. The challenge is in acquiring competent individuals who can assure that all the data within the system is at its optimum operating integrity.

The third, and final challenge that has been encountered in the use of the CIM system is process control. This entails assuring that the whole process runs smoothly. This particular challenge ties the data entry people, the programmers, and the production operators together. The factory will need to assure that the individuals working with the system throughout the factory are competent and knowledgeable. These individuals will need to be well trained, and probably need to update their training periodically.

The goal of the CIM system is to eliminate the waste within the manufacturing process. This is done by taking the design, analysis, planning, purchasing, cost accounting, inventory control and distribution departments and interlink them with the factory floor, material handling, and management departments. The CIM system will have an impact on every system within the factory.

The CIM system, which is sometimes referred to as the integrated computer aided manufacturing system, operates on both hard and software. Simply put, the software is what runs the factory, or the brains. The hardware is what makes the machines run, or the muscles. The CIM system runs on an efficient output process. This means that the whole factory works together, not as separate parts. As a unified unit, it operates for the peak benefit of the whole factory.

Simply put, the CIM system does not backload or store up work. It does not warehouse products. The CIM system keeps work flowing through computer integration in order to keep all the parts of the system constantly functioning. It registers all the raw material received by the factory. It then walks the material through the factory and the production process.

The CIM system fractions every individual "center" of the factory into work cells. As work cells, they are then divided into individual stations. The stations are then broke down to the individual processes, and the processes are what metamorphosizes the raw materials into actual products. This may seem complicated, but it streamlines the whole manufacturing process. With each division of the factory broken down in such a manner, it allows operators to make any necessary changes to the system without shutting down the whole system.

Cim is a very interactive, hands on system. If it is applied correctly, it will enhance the productivity of the whole factory. It will link several departments and functions together. It is simple to install. It usually is installed through a LAN, or local area network, connection.
