13. Engineers make use of machine tools in all their activities. List as many

applications of machine tools as possible. Compare your list with that of

your group mates.

14.Paul, a student of Mechanical Engineering, has visited an exhibition

"Advances in Machinery Engineering" and now he is telling his friend

Alex about it. Listen to their dialogue and learn how to name different

machine tools.

Alex: Hello, Paul! Glad to see you. Where have you been? I was look¬ing for you all day yesterday. But unfortunately, I didn't find you.

Paul: You know, our lessons had been finished by five o'clock yes¬terday and I went to our Exhibition Hall and saw different types of machine tools there, such as lathes, milling machines and grinding machines.

Alex: That sounds interesting. It's impossible to imagine a work shop today that is not equipped with multi-purpose machine tools.

Paul: I can't but agree with you. People have already fully auto¬mated all transportation operations.

Alex: And were there any interesting types of machine tools at the Exhibition, I wonder?

Paul: Oh, definitely, the latest developments in the design of machine tools were well represented there. And as far as I know, some of these types will have been put into operation by the end of the next year.

Alex: And what impressed you most of all at the Exhibition?

Paul: Well, you know, there was one fantastic machine known as the "machining centre". This machine performs about a hun¬dred different operations simultaneously.
