Abstract

PURPOSE:To facilitate accurate discrimination of any damage of a cutting tool, in such a way that when gross output of frequency components in AE signals exceeds the reference value, an alarm device is actuated. CONSTITUTION:While a pressure sensor 10 which operates only at the time of cutting is in operation, detected AE signals are entered into the next amplifier 3, and amplified. And since only constant frequency components are entered into an integrator 5, AE signals are integrated with the lapse of time, their values are compared with reference values in a comparator 7, and an alarm device 8 is actuated when gross output P of frequency components in the AE signals exceeds the reference value P1, any damage of cutting tool can be accurately discriminated.
