Abstract
PURPOSE: To automatically determine the quality of a cutting tool by raising a warning signal when the integral value of signals obtained from the vibration of the cutting tool reaches a given level within a specific time.
CONSTITUTION: The output of a detector 1 for checking for the vibration of a cutting tool is amplified with an amplifier 2 and inputted to an integrator 3. The integral value of vibration signals integrated during a preset period of time is compared with the reference voltage set with a reference voltage source 5 by means of a comparator 4. When the resulting difference reaches a preset value, a warning signal is emitted. This enables automatic discriminating of quality of the cutting tool and raising of a warning signal.
