No one wants a hand-made car or gun or an airplane. We want things made by machines. Machine tools are power–driven machines–of all shapes and sizes-used to make metal parts. Machine tools built our modern world. Our life would not be possible without them. This show will take a look at these amazing machines in action . Beginning with the story of the steam engine and traveling to modern day “machining centers”–used to make incredibly complex space shuttle parts–we’ll look at the basic types of machine tools and their development. We’ll also look at some of the most modern machine tools of the future, including machines that are changing the way products of tomorrow are made.
