Tool wear is the gradual breakdown of machine tools as a result of cutting operation, eventually leading to tool failure. Because tools and workpieces are in constant contact with severe friction and rubbing, tools become stressed over time. This stress is the result of metal-to-metal contact and high stress and pressure.
