1. Read and translate the text Computer Integrated Manufacturing. Computer Integrated Manufacturing (сім)

The term "computer-integrated manufacturing" is both a method of manufacturing and the name of a computer-automated system in which individual engineering, production, marketing, and support functions of a manufacturing enterprise are organized. In а СІМ system functional areas such as design, analysis, planning, purchasing, cost accounting, inventory control, and distribution are linked through the computer with factory floor functions such as materials handling and management, providing direct control and monitoring of all process operations.

Computers may be used to design a product to control machines, and to link design and processing operations together. Computers are also used in other areas of a company. Records for payroll, sales, personnel, distribution, and accounting are also kept on computers. Many companies keep these different operations separate. In computer-integrated manufacturing (СІМ), however, they are all linked together.

CIM requires a “mainframe” computer. A mainframe is a large computer to which many workstations can be attached. Information from all areas of the company is stored in the computer. When one department wants to know what another is doing, it simply calls up the information needed.

In computer-aided manufacturing, every machine in production is run independently of the others. When СІМ is used, however, the computer links all the machines. If one operation runs into a problem, the other operations are automatically adjusted. The work is more efficient. Fewer mistakes are made.

Just-in-time (JIT) delivery methods are used with computer-integrated manufacturing. Because the computer controls all inventories, last-minutes orders are more accurate. An up-to-date record of all materials and suppliers is also available.

Because computer-integrated manufacturing has many advantages, its use will continue to grow. It reduces the chance of two different departments doing the same work. Information about the entire company and its operations is always available. Efficiency and profits are improved. The heart of computer integrated manufacturing is CAD/CAM. In the past, product design was drawn using paper and pencils and other drafting equipment. As changes in the design were made, the drawings had to be redone. The process could take days.

Today, products can be designed using computers. This is called computer aided design (CAD). Special software (computer instructions) allows drafters to draw anything that used to be drawn on paper. Changes can be made quickly and easily. What used to take days may now take only hours.

When computers are used thought production, it is called computer-aided manufacturing (CAM). CAM reduces production costs by reducing the numbers of workers needed. Parts are machined more quickly and accurately. CAM/CAD is the combination of computer-aided design and computer-aided manufacturing. Parts are designed on a computer. The design is then sent to the computers that control the machines. These computers "read" the design and tell the machine how to make the part. With CAD/CAM, computers talk to computers. This speeds up and improves the accuracy of the manufacturing process. Computerized manufacturing has several advantages. Because computers are fast and efficient, they help reduce production costs. They also make it easier to change a product.

For example, new car models are a little different from last year's models. Computers can help decide the best and cheapest ways to make the necessary changes. Also, with such computerized devices as robots, dangerous jobs can be done safely. There are some disadvantages, however. Computerized manufacturing is very expensive to set up. Small firms may not be able to afford it. Computers require highly skilled workers to install and mainframe them. The wages of these workers may be very high. Also, many employees lose their jobs when computers replace them.
