| description | A device for determining cutting tool wear and breakage has an accelerometer for sensing tool vibrations. Functions of the AC and DC power of the vibration signal, such as the powers themselves or the square root of the powers, are computed and compared. If the relationship between the AC and DC power changes beyond selected limits, an alarm is sounded or flashed. A method for determining cutting tool wear and breakage provides a tool vibration signal, computes functions of the AC and DC power of the vibration signal, and compares the AC and DC power signals. |
