ABSTRACT:
The tool monitor according to this invention comprises an acoustic emissions (AE) sensor to be mounted in the neighborhood of and without contact with a machine tool and a tool damage detection means adapted to detect any damage to a tool of the machine tool according to a level of an output AE signal within a predetermined frequency band generated from the AE sensor at the time of occurrence of damage. Since this AE sensor is not in contact with the machine tool spindle, work table or work piece, it is easy to set the sensitivity of the AE sensor and variations in the AE sensor output signal level are minimized. The AE sensor is also effectively protected against flying chips, and noise due to contact with the chips is reduced, thereby minimizing the possibility of erroneous operation.
