11. Переведите текст письменно со словарем.

It is often at process control level that are used the assembly rules which drive the robot, conveyors and system as a whole. Hence it is important to insert at this level the means to check on whether the tasks are being carried out satisfactorily.

Usually this is done by checking on whether certain digital inputs and outputs have been set. The important thing is to decide what you really need to know and when. A vision system can be a very flexible tool: it can give the robot precise positional information, it will respond to the process control demands only if the specific part required is found, it can carry out inspection tasks etc. but it is expensive and must be applied by experienced people – however it is a powerful tool.

5. Переведите предложения, учитывая значение предлогов for, from.

1. The assembly process suffers disturbances not only from internal sources, but also from external ones.

2. For the better classification of the diagnosis strategies, it is reasonable to divide the faults into internal and external.

3. These conditions are significantly different from normal.

4. A set of symptoms characteristic for the particular failure is called a syndrome.

5. For the testing, there is a great number of procedures available.

6. Переведите предложения. Выпишите подчёркнутые наречия с переводом.

1. Hence, we can eliminate the need for several smart sensors.

2. However, this is not enough in itself.

3. The requirements of the assembly system must be worked out beforehand.

4. Consequently, a high degree of reliability is very important in the assembly symptom.

5. The diagnosis function is separately cooled and is therefore portable on to additional hardware.

7. Переведите предложения, учитывая особенности перевода слова "it" (Приложение 2, табл. 16).

1. It is no exaggeration to say that the need for geometric adapting control systems is much more obvious than the number of available systems.

2. There are many ways of considering the cell of factory automation. It can be viewed in almost biological way as the smallest autonomous unit capable of sustained (усредненный) production.

3. The cell can also be viewed in terms of item that it usually contains. In this way we can see it as a small collection of machines which are closely cooperating with each other.

4. It seems unlively in the foreseeable future that the completely unmanned factory is practical, desirable or financially justifiable.

5. In factory automation it is usual to take account of the capability of manufacturing process.

6. It is not clear whether the cellular approach reduces the complexity of the overall system control problem.
