Machine Tools TodayMost of the early machine tools featured at the American Precision Museum were designed to shape metal parts. Today, machine tools shape many other materials, but ultimately all mass-produced goods depend upon metal-cutting machine tools. Either they contain precisely made metal parts or they are made by machines that are constructed of precisely made metal parts. In either case, their uniformity and low cost depend upon machine tools.
Today, machines controlled by computers function automatically, performing operations and changing tools according to numerically coded instructions. Machining today requires new skills, such as computer programming. But it also still requires the machinist to understand relationships, procedures and tolerances. The machinist must also have the craftsman's ability to conceive a product and develop a method to create that product.
From the beginning, machine tools have transferred skill from the hands of the worker to the machine, but the source of that skill has always been the human mind. Machine tools save physical labor and increase productivity, but they do not eliminate the need for intellect. They shape our world by providing an ever-expanding array of products and opportunities. They also demand of us a higher and higher level of education and technical understanding if we wish to stay at the cutting edge.
