Abstract
PURPOSE: To readily integrate only the time making contribution to cutting and perform the highly accurate measurement of tool life by such things as operating a timer according to the detection of the acoustic emission (AE) signal generated by a tool at the cutting.
CONSTITUTION: The frequency components of the frequencies 100kHz or less, which do not contribute to cutting, out of the AE signal outputted by the detector 1 provided to the tool are removed by a discriminator 3. If a timer 4 is operated according to the output of this discriminator 3, the cumulative cutting time is compared with the set life time having been set in a comparator 5 and stopping of the working or other is done by controlling a switch 6, then the life time of the tool is measured highly accurately according to the integration of the time having actually contributed to the cutting and the stopping of the machine tool, etc. may be automatically controlled.
