III. Make up a dialogue using the questions to Text 9. Text 12 m odern machine tools

M odern machine tools are capable of processing ultrahard metals not machinable by other methods. Machine tools that form parts by removing metal chips from a work-piece include lathes, shapers and planers, drilling machines, milling machines, grinders, and power saws. The cold forming of metal parts, such as cooking utensils, automobile bodies, and similar items, is done on punch presses, while the hot forming of white-hot blanks is done on forging presses. Modern machine tools cut or form parts to tolerances of plus or minus one ten-thousandth of an inch (0.0025 millimeter). In special applications, precision lap­ping machines can produce parts that are within plus or minus two millionths of an inch (0.0³5 millimeter). Because of the precise dimensional requirements of the parts and the heavy cutting forces exerted on the cutting tool, machine tools combine weight and rigidity with delicate accuracy.
