History
But it was not until the later Middle Ages and the Age of Enlightenment that the modern concept of a machine tool—a class of machines used as tools in the making of metal parts, and incorporating machine-guided toolpath—began to evolve. Clockmakers of the Middle Ages and renaissance men such as Leonardo da Vinci helped expand humans' technological milieu toward the preconditions for industrial machine tools. 
when was the first man made diamond made 1954 what are the materials required to make this? Pure carbon, the belt press, the cubic press and the split-sphere (BARS) press. what temperature-pressure conditions are required fopr this? High pressure, high temperature. can you mention any of its uses? Machine tools and cutting tools; as a Thermal conductor; as an Optical material; semiconductors ; gemstones what is the first one? A machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformation can you provide me the historical background for such tools? Forerunners of machine tools included bow drills and potter's wheels, which had existed in ancient Egypt prior to 2500 BC, and lathes, known to have existed in multiple regions of Europe since at least 1000 to 500 BC.

Clockmakers of the Middle Ages and renaissance men such as Leonardo da Vinci helped expand humans' technological milieu toward the preconditions for industrial machine tools. During the 18th and 19th centuries, and even in many cases in the 20th, the builders of machine tools tended to be the same people who would then use them to produce the end products (manufactured goods). However, from these roots also evolved an industry of machine tool builders as we define them today, meaning people who specialize in building machine tools for sale to others. .

Machine tool [SEP] History
Cast iron could be cast in molds for larger parts, such as engine cylinders and gears, but was difficult to work with a file and could not be hammered. Red hot wrought iron could be hammered into shapes. Room temperature wrought iron was worked with a file and chisel and could be made into gears and other complex parts; however, hand working lacked precision and was a slow and expensive process.
