Нужен перевод текста ,срочно !! what does an automated assembly line look like ? At the beginning of the line is a skeleton chassis. It has been lowered onto a moving truck by a robot crane. As it moves along , a robot drill press bends over , whirls a few minutes , and lifts . A few feet further along the line a metal hand drops a motor brace on the chassis . The rivets on the brace fit the holes drilled by the press . The metal hand holds the brace firmly in place and goes back . The car moves along the line . At each position apert is added and fastened . When the inside of the car are put in place , the assembly line reaches a second line. This is the line where the outer shells of the car are put together . In the same way thet motor , steering wheel, wheel , brakes , and other things have been added to the inner part of the car, fenders , hood , doors , accessories have been added to the body along another line . After that the car goes through apaint booth furnished with hightemperature drying lights . Finally it is at the end of the line - a finished car , as, yet untouched by human hands . On the assembly line , the complete engine is dropped onto the car. Where did that engine come from ? From the automated engine shop . In the engine shop , rows and rows of machines can be seen. They grind, drill, ream, polish , and periorm dozens of other operations . But not a machine operator can be seen . They can't be seen becaus there aren't any. these machine tools are all robot-run . A roughcast engine , fhresh from the foudry , enters the machine shop on a belt . The belt moves it under one machine. Reamers drop down and clean out the cylinders' holes, cutting and grinding the metal to the exact size . The engine moves on. Drill presses drop down, bore holes where they are needed, and withdraw. As the engine moves down the line , rappets , cilinders, crankshafts and spark-plugs are added. Then generator, fan,carburetor, and other parts. At the end of the line a robot crane picks up the engine and puts it on a belt for transfer to the main assembly line. In another part of the factory greatsheets of metal are put into giant rollers . The rollers twist , bend doors and bodies. These , too, are automatically assembled , then moved to the main assembly line . Each machine must be set so thet it will co-operate with all other machines in the factory.
