Machine tool Tool materials Britannica

Machine tool Machine tool Tool materials: In order to remove chips from a workpiece, a cutting tool must be harder than the workpiece and must maintain a cutting edge at the temperature produced by the friction of the cutting action. Steel with a carbon content ranging from 1 to 1.2 percent was the earliest material used in machine tools.Metal Fabrication: A Guide to Manufacturing Metal Parts,Over the past 150 years, machine tools have grown from crude pulley and steam driven devices to the high-tech, ultra-precise computer numerical control (CNC) equipment of today.
