Machine tools are specialized devices used to shape, cut, or form materials, primarily metals and plastics. They operate by removing material from a workpiece to create desired shapes and sizes. Common types of machine tools include lathes, milling machines, and drills, each designed for specific tasks in manufacturing and fabrication. These tools are essential in various industries, including automotive, aerospace, and construction, as they enable precise and efficient production of components. Machine tools can be operated manually or controlled by computer numerical control (CNC) systems, which automate the machining process for increased accuracy and repeatability.
