Machine Tools as a Measure of Man’s Progress
The variety of combinations of machine tools 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 work shop. They are turning, drilling, threading, etc.
Technological progress improves accuracy of machine tools. Todays’s equipment can produce parts with very high accuracy. One can find a number of machine tools that can measure and inspect their production themselves, they can handle the parts mechanically and automatically.
Since machine tools become faster and more complex, automatic measurements and inspection ought to be of greater importance. Automation is one of the main factors of engineering progress.
