Machine tools mean any stationary electrical machine used to form or form parts of metal or other materials. Forming is accomplished in four general ways: Cutting excess material as chips from the part By sharing the material By pressing the metal parts into the desired shape Applying electricity, ultrasound, or caustic chemicals to the material The fourth category includes modern tools and processes for machining ultra-hard metals that are not machinable with older methods. Modern tools cut or form parts to tolerances of plus or minus ten-thousandth of an inch (0.0025 millimeters). In special applications, precision lapping machines can produce parts within plus or minus two-millionths of an inch (0.00005 millimeters). Due to the precise dimensional requirements of the parts and the heavy cutting forces exerted on the cutting tool, tools combine weight and stiffness with delicate precision.
