Переведите текст. the variety and combinations of machine tools today are unlimited. some of them are very small and can be mounted on a work bench*, but others are so large that we have to construct special buildings to house them. there are some basic operations at any workshop. they are transporting, turning, drilling, measuring, size controlling, etc. the main machine tool of such a workshop is the multipurpose lathe*. what is a lathe? it is a power-driven machine with special tools, which can cut or form metal parts. the metal that cuts another metal must be very hard, and so tools should be made of very hard steel alloys. the tool itself is very small in comparison with the mechanism which is to direct it. technological progress improves accuracy of machine tools. today’s equipment can produce parts with very high accuracy. one can find a number of machine tools that can measure and inspect the main production parameters themselves - machine tools that are to handle the parts mechanically and automatically. such machines can hold the parts, which are to be measured and are able to indicate precise measurements themselves. a great many of such "clever" machines can be found today in our industry. since machine tools become faster and easy to operate, and more complex too, automatic measurements and inspection ought to be of greater importance and precision. automation is one of the main factors, which effect engineering and, thus, man’s progress.
