Types of automation. Applications of automation and robotics in industry

Manufacturing is one of the most important application areas for automation technology. There are several types of automation in manufacturing. The examples of automated systems used in manufacturing are described below.

1.Fixed automation, sometimes called «hard automation», refers to automated machines in which the equipment configuration allows fixed sequence of processing operations. These machines are programmed by their design to make only certain processing operations. They are not easily changed over from one product style to another. This form of automation needs high initial investments and high production rates. That is why it is suitable for products that are made in large volumes. Examples of fixed automation are machining transfer lines found in the automobile industry, automatic assembly machines and certain chemical processes.

2. Programmable automation is a form of automation for producing products in large quantities, ranging from several dozen to several thousand units at a time. For each new product the production equipment must be reprogrammed and changed over. This reprogramming and changeover take a period of non-productive time. Production rates in programmable automation are generally lower than in fixed automation, because the equipment is designed to facilitate product changeover rather than for product specialization. A numerical-control machine-tool is a good example of programmable automation. The program is coded in computer memory for each different product style and the machine-tool is controlled by the computer programme.

3. Flexible automation is a kind of programmable automation. Programmable automation requires time to reprogram and change over the production equipment for each series of new product. This is lost production time, which is expensive. In flexible automation the number of products is limited so that the changeover of the equipment can be done very quickly and automatically. The reprogramming of the equipment in flexible automation is done at a computer terminal without using the production equipment itself. This type of automation allows a mixture of different products to be produced one right after another. The examples of flexible automation are: technological robotic complexes, automated production lines of print-wire assembly and others.

Task 3. Find in the text the English equivalents for the following.

  1. область (сфера) применения;

  2. фиксированная последовательность операций;

  3. высокие производственные темпы;

  4. автоматические сборочные машины; 5. большое количество;

6. производственное оборудование; 7. для каждого различного вида продукции; 8. потеря производственного времени;

9. переустановка оборудования; 10. производить продукцию одну за другой.

Task 4. Complete the sentences taking the necessary information from the text.

  1. There are three types of automation in manufacturing. They are ... .

  2. Fixed automation needs …. 3. … are the examples of fixed automation.

4. Programmable automation is applied for ... . 5. A good example of programmable automation is ... . 6. Flexible automation requires … . 7. … is done at a computer terminal without using the production equipment.

Task 5. Answer the questions.

  1. What is the most important application area of automation?

  2. What automation types used in manufacturing do you know?
