This paper describes a new diagnosis technique of tool life in diamond turning of coppers. A diamond cutting tool closes generally the useful life by gradually increasing face wear and sudden chipping of the cutting edge. Therefore, the cutting force and acoustic emission (AE) have been analyzed to detect each type of tool wear in turning processes. As a result, it was found that the development of face wear generates the 1/f^β noise to the cutting force, and the occurrence of chipping releases the AE which has the amplitude distribution spectrum, the scaling exponent of which is less than 2. Tool life tests also showed that these extracted features could be used as the criterion for the judgment of tool life under a variety of cutting conditions.
